ASP.NET vs PHP: Which One To Choose and Why For App Development?

Businesses have no choice but to move to the online world. Even an entrepreneur today thinks of launching online first then setting up things in the offline space.

However, the road ahead has not remained as smooth as it was earlier. Application development processes are something that is evolving continuously due to the influencing factors like version updates in programming languages, frameworks, and libraries, and then is the emerging programming languages, frameworks, and libraries.

Even after receiving a bundle of updates, innovative libraries, and framework support, the debate for using ASP.NET vs PHP has not seen an end.

Both technologies have always emerged stronger and give a neck to neck competition to each other for the title ‘The Best’. So let’s not waste too much time here, and jump into the two dominating technologies and find which one is best to choose for app development.

But, first, understand both ASP.NET & PHP.

PHP & Its Business Use-Cases

PHP or Hypertext Preprocessor is a high-level, dynamic, and scripting language. It is widely used in web page development and web services on the server-side. A well-known server-side scripting language, PHP is often used instead of Python.

PHP has witnessed backlog since the beginning as it does not utilize a ‘managed code system’, thus considered less secure, however, it allows developers to be more creative while writing programs.

Using PHP, developers can design web elements in a unique way that is not dictated by the managed code system of the .NET family. Additionally, PHP is flexible due to being open source. It can run on any platform.

Advantages of PHP

Advantages of PHP
  1. Gather user information with the use of forms
  2. Collect information automatically from various web pages and from all over the Internet
  3. Create a membership option for your website
  4. Generate dynamic files and webpages
  5. Track users with the help of cookies
  6. Add any kind of dynamic function you can come up with
  7. Create desktop applications
  8. PHP has some incredibly useful text processing features
  9. It’s incredibly easy to find hosting for PHP
  10. PHP has a wide range of powerful built-in functions

ASP.NET & Its Business Use-Cases

ASP.NET is a web development framework by Microsoft and typically uses C#. The framework requires developers to work by certain rules such as the managed code framework which governs the run-time of code execution. 

When using ASP.NET, developers don’t enjoy a lot of freedom as they have to write an app with the “rule-based” nature of .NET. But allows them to use modules, which is sometimes forced by the managed code system, to work together. This, in turn, makes development, testing & deploying apps much more seamless and quicker.

Since developing robust sites utilizing the ASP.NET system, it does not require extensive code from scratch – and ASP.NET can be integrated with powerful Microsoft systems, such as Microsoft SharePoint for App Development, management, and deployment across the board – web development with the framework is often less resource-heavy.

As has been noted, ASP.NET Core, formerly known as ASP.NET allows cross-platform development as well, which mitigates the costly Windows licenses required for the .NET Framework and Microsoft Servers. 

Advantages of ASP.NET

Advantages of ASP.NET
  1. It supports flexible programming due to carrying object-oriented features
  2. It supports ‘separation of concern’ as follows MVC patterns in app development. It also simplifies maintaining the app
  3. It promotes test-driven development, thus unit testing enables developers to be more productive
  4. Has a mature framework due to having task-based libraries. Whether it requires to edit an image or XML, developers share ample of time doing things.
  5. Its event-driven programming nature promotes the simple app development process
  6. It supports many different languages such as C#, C, C++, Jscript.Net, VB. Net and a lot more. Developers can choose to write code in their preferred programming skills

Both languages have their pros, they also have their fair share of cons

  1. High upkeep costs
  2. Hard to Understand the Application Flow
  1. Various security flaws
  2. Not so good for developing desktop applications
  3. PHP has a weak type


It’s easy to compare one language to another, but the debate never ends until businesses find the answer to “which one should I choose for the application development?”

Besides, ASP.Net and PHP have not seen a major drop in popularity and adoption.

PHP, with 26.4% growth, has acquired 8th position as one of the most popular programming languages in Stackoverflow Developers Survey 2019While ASP.NET made the 4th position as one of the most popular web frameworks where it didn’t even make an appearance in the survey of 2018.

However, if we compare the market share of ASP.NET and PHP, the latter leads the way with huge numbers to report. One such report shared by similar tech.


PHP even has better usage coverage in multiple website categories. Just look at the stats below image. 

php better option for websites

In a general way, PHP is leading the way whereas ASP.NET has miles to cover.

Here, it is important to understand how ASP.NET has made it to Stackoverflow’s survey list if PHP has this sort of popularity and adoption.

This is where we have to adopt a different method to differentiate between ASP.NET vs PHP. 

As we mentioned earlier, PHP is a programming language whereas ASP.NET is a framework. Therefore, if we compare a framework to a framework i.e. ASP.NET to Laravel(it is the most advanced PHP powered framework today) we get completely different results. 

ASP.NET has approximately 2,417,820 websites whereas Laravel shrinks to only 123,513. Moreover, ASP.NET leads the way in terms of market share as well as website categories.

To shed some more light on ASP.NET vs PHP, it is also important to compare a programming language to a programming language i.e PHP vs C# (C# is a primarily used programming language in ASP.NET).

Let’s take a look at Google Trends’ report below

interest trend for php vs c

Over the past five years, PHP has been a more popular search term than C#.

C# is more widely used in NON-WEB applications than PHP, which is used as a general-purpose programming language. It is used for Windows phone apps, tools, and even cross-platform mobile frameworks (MONO).

C# is an object-oriented programming language whereas PHP is NOT.

Even with 31% growth, C# has attained 7th place in Stackoverflow 2019 survey and maintains a lead over PHP. Still, PHP is more popular and widely used over C#. 

To decide which technology, however, is suitable for application development, businesses have to decide the purpose of the project. 

Deciding on ASP.NET vs PHP for App Development?

There are several components that need to be considered to decide the tech stack for the website/application development. Almost every application/website requires to be scalable, quick in performance, provide security, ensure smooth functionality, look aesthetic, support seamless integrations and cost-effective.

Therefore, a company’s strategic plan should revolve around the following differentiation to align with the goals of the company. 

Major Difference b/w ASP & PHP

  1. Web Application Framework and a Microsoft product
  2. Ideal to build medium to large size enterprise apps
  3. Major focus on security and functionalities
  4. Dedicated community with growing developers
  5. Highly Secure
  6. Decent speed, fast enough for a desktop application
  7. Less prone to customization
  1. Server-side scripting language. Used by Google, Facebook, Yahoo and more
  2. Widely used to create small to medium-sized web solutions
  3. More focused on client-facing, user interfaces
  4. Large size community
  5. Less built-in security feature
  6. Not suitable and slower for a desktop application
  7. Allows customization which can cause bugs, thus poor coding than .NET

However, a business must differentiate the two on the following parameters:

  1. ASP.NET is made for windows platforms primarily, thus it has a heavy dependence on the platform. When it comes to using ASP.NET, it is important for developers to use Microsoft Visual Studio during the development process.
  2. Microsoft and Stackoverflow are built using ASP.NET and are highly scalable.
  3. ASP.Net gives complete control over the project including the writing of code and architecture implementation that defined the good performance of the website.
  4. Using ASP.NET involves a time-consuming process as ASP has to be complied with every time to ensure modifications in the code.
  1. PHP is compatible with different platforms such as Linux, UNIX, Windows and almost everything you would use it for. Therefore, PHP is supported by numerous IDE’s available for free and paid as well.
  2. Facebook and Wikipedia are PHP based websites, thus there is no doubt PHP can be your choice if you want it to choose. However, PHP is a more reliable choice if you want to develop a website through a content management system such as Drupal, Joomla, or WordPress.
  3. PHP, yet also is faster. It is behind Facebook, Google, and Yahoo.
  4. PHP is interpreted on the server, therefore it involves comparatively less time in deployment.

As we have seen, it is tough to differentiate between ASP.NET and PHP. Over time, PHP has received comprehensive community support. Thus, different frameworks and integrations are available to support it.

On the other hand, ASP.NET is a Microsoft product and is a standard framework that makes it popular among developers interested in building standard websites.

Then how would you decide which technology is best for their business?

To find the answer to that question, it is important to understand Who will be in contact with your content?”

Both the technologies considered best to use the following:
  • Commercial Web Sites
  • General Web Development
  • REST Based Web Services
  • Desktop Applications
  • Server Scripting

Consideration between ASP.NET and PHP wouldn’t end until businesses shed light on the website whether it is client-facing or internally/business-facing. As mentioned on PHP’s official website, ‘PHP powers everything from your blog to the most popular websites in the world’.

PHP may benefit external websites more, whereas ASP.NET may better be left for business-facing websites/apps.

Let’s try to understand the importance of PHP and ASP.NET in security, optimization, performance, aesthetics, and functions. Also, understand how important these are for external and internal websites/apps.

Client Facing Websites

PHP was originally innovated to enable more optimized and better-looking web page development. It comes with a set of tools that supports the developer’s creativity, thus a business gets better looking and better-performing websites.

Being so if we look closely, PHP is considered best to develop for more personal and business websites, including social media websites like Facebook uses PHP and refactored using HPHPi & HHVM.

PHP ensures the needs of externally-facing websites such as optimization, aesthetics, and performance.

Internal Websites

When a website/app needs to be developed for a business within a corporation’s intranet, then security and functionality become crucial along with integration with enterprise IT systems.

Due to being a managed code system, ASP.NET shines in providing enterprise solutions. ASP.NET secures code at run-time, as the framework lets the developer build the website keeping functionality in mind. ASP.NET is widely used for web services development and mostly websites deployed on windows systems and/or IIS.

As ASP.NET is a Microsoft product itself, integration of other Microsoft services with it greatly increase the workflow efficiency, productivity, and management of company operations/projects.

Though ASP.NET is not a good choice to build end product appearance as appealing as PHP, it definitely should be your choice while developing an internally-facing website/app to make it secure and highly functional. It can help personnel with the required resources to complete daily workflows/projects.

Cost Advantage?

We already know PHP is open-source and thus it is easy to declare it a winner when it comes to cost-effectiveness. ASP.NET is available for free to use, though for integration, hosting and other app requirements, Microsoft charges a fee for it.

Though, the fee charged by Microsoft is not high but when compared to free usage that PHP and its supportive technologies provide makes developers skeptical towards ASP.NET. 

ASP.NET has cost included, it doesn’t, however, stop developers from building a website with Microsoft’s framework. 

Wrapping Up

There are scenarios where PHP is the right choice while in other cases ASP.NET fits better. Before settling on the choice of which platform is progressively appropriate, you ought to ask the following things:

  • How much budget do you have for the project? (When low budget go for PHP, while on a healthy budget you have the option to go for ASP.NET)
  • Which of these technologies does your development team know better?
  • What are the prerequisites and end-user needs?

In the wake of responding to these basic questions, you ought to get a look at understanding which might be better for your business application.

It is very little either platform can’t achieve, henceforth you have to go a little deep to analyze the suitability of each language as opposed to their popularity.

How to secure uploaded file over server using PHP

How to secure uploaded file over server using PHP
Uploading a file (such as an image, zip, or PDF) is quite common in website development, and PHP makes the process very simple with the move_uploaded_file method. But hackers are always on the lookout for easy prey, such as .exe, PHP, and scripting files.

Although this does not guarantee that after this your code and server will be fully protected from hackers. but something is better than nothing.

Below are some tricks that you can use while writing code for file uploading –

PHP Server

Step 1:- Set File permission:

Before placing the file on the server, you may add non-executable permission to it. The server will be safe from executable and scripting files using this approach. You can use PHP’s chmod() function to change file permissions.


if(move_uploaded_file($_FILES[“uploadedfile”][“tmp_name”], $target_path)) {

         chmod($target_path, 0755);


         echo “There was an error uploading the file, please try again!”;



Step 2:- Use getimagesize method:

A very common trick used by hackers is changing the content type of a file to a valid one. To ensure that the uploaded file is a valid one or an image file, you can use the getimagesize() method.

$imageinfo = getimagesize($_FILES[“uploadfile”][“tmp_name”]);

     if($imageinfo[“mime”] != “image/gif” && $imageinfo[“mime”] != “image/jpeg” && isset($imageinfo))


         // invalid file



Step 3:- Create an upload folder outside of root:

The best way to avoid users from requesting uploaded files straight away is to keep the file in a folder outside the root. However, the major disadvantage with this method is that after this server will be unable to access the file.


Step 4:- Use .htaccess file:

You can set permission and prevent hackers to access files by making changes in the .htaccess file, If somehow hackers upload a file this will prevent executing a file.

Step 5:- The Include Function:

Sometimes you need to obtain input from the user in order to determine which file should be included in the PHP script. For example, suppose your site is called Site_languageuage.


     $Site_language = $_COOKIE[‘Site_language’];

} elseif (isset($_GET[‘Site_language’])) {

     $Site_language = $_GET[‘Site_language’];

} elseif (isset($_GET[‘Site_language’])) {

     $Site_language = $_GET[‘Site_language’];

} else {

     $Site_language = ‘english’;


$siteLanguagePath = “Language/”.$Site_language;


Now there is no security for the input of site_language, An hacker can take benefit of this and enter the path of the file that he wants to execute.

As a result, to guarantee that hackers do not upload any harmful files to the system, you must secure your input/upload feature.

Step 6:- Rename file with an auto-generated name:

While uploading to the server, it is a good idea to change the file’s name. Hackers would find it difficult to figure out the name of the file and then hack or download it from the server.

It’s possible to encrypt and decrypt files using a variety of methods, including md5, for example. Alternatively, you might use self-encryption to encrypt and decrypt file names.

Step 7:- Restrict upload file size by html or PHP code:

You may secure your system by restricting or limiting the file size that can be uploaded. It will prevent users from uploading a huge file that would exceed the limit and cause problems to your system.

You can make these changes by using html as well as PHP script


<input type=’hidden’ name=’MAX_FILE_SIZE’ value=’100000′ />


$max_file_size = 100000000;  

if(!$file_size || $file_size > $max_file_size) {

     echo “File size is more than maximum size limit”;



Step 8:- Verify session authentication:

After successful authentication, you may also check session authentication and enable file upload functionality.


You can also add a captcha to provide security against automated scripts. There are still several techniques available to us to safeguard your server from hackers and prevent them from uploading harmful material –


– Check the mime type

– Use an anti-virus

– Use a combined protection

– Use a different subdomain for uploading purpose

Each day new techniques are discovered to stop hackers from such work so keeping you update is best practice to keep your data secure.


In website development, uploading a file (such as an image, zip, or PDF) is quite common, and PHP makes the procedure straightforward with the move_uploaded_file method. However, hackers are always looking for easy prey such as .exe, PHP, and script files. We hope that this blog helped you in some manner. Keeping up with the latest methods to defend yourself from such jobs is essential in order to keep your data secure.
