ASP.NET Vs. PHP: Which is Better?


ASP.NET vs. PHP is one of the hottest comparisons developers come across while selecting from these leading technologies for their business or project, as they both have broad bases and comprehensive tool support.

Since both are popular in the web development world, selecting the right one is tricky. We aim to highlight-guide you in choosing the best one for your organization.

What is ASP.NET?


ASP.NET is a popular web development platform and provides a comprehensive software infrastructure, a programming model, and various other mandatory services to create robust web applications for mobiles and desktops.

ASP.NET was released in early 2002 as a successor to Microsoft’s ASP (Active Server Pages). Creating .NET applications is relatively easy with ASP.NET as it is a language-independent software allowing developers to select any .NET supported language.

Apart from its different libraries, ASP.NET also provides several development toolkits that make the app, dynamic web pages, microservices, and REST APIs creation more accessible and seamless.

Some popular websites built through ASP.NET are Visual Studio, DELL, Microsoft, StackOverflow, and GoDaddy.

Advantages of ASP.NET

  • ASP.NET is highly scalable and gives tough competition to PHP in scalability.
  • Support almost all major programming languages, including C#.
  • Capable of highlighting mistakes made by the developers during the coding part before compiling.
  • Support programmers with popular tools and advanced features.
  • ASP.NET works smoothly with Windows OS.
  • Provides the best platform for Enterprise applications.
  • Pre-coded features for fast development.
  • Smart UI to navigate and use different features seamlessly.

Disadvantages of ASP.NET

  • Tough to understand and learn for new developers.
  • A small support community to help developers.
  • The Microsoft license makes it more expensive.
  • Not as suitable as PHP for website or application development.

What is PHP?


PHP started as an open-source web development project and later evolved over the years with new features and tools. It’s the same reason PHP comes to everyone’s mind when discussing web projects. PHP allows integration with several popular databases efficiently. To interpret PHP code, there’s a PHP interpreter implemented in the web server as a module.

The web server first combines the results of both executed and interpreted PHP code. These codes could be of any type, including images too. In its execution, you may find PHP smugly zippy; however, the execution works even smoother on the Unix side when compiled as an Apache module. PHP also supports major protocols like- LDAP, POP3, and IMAP.

PHP is a recursive acronym for HTTP processors, and as a web development framework, PHP is embedded in HTML. PHP developers are provided with various open-source libraries and applications to make web designing more efficient and easy. Therefore, PHP is compatible with different web applications, and unsurprisingly, many of our favorite social media sites are written in PHP code.

Some popular websites powered by PHP are MailChimp, Facebook, Flickr, Wikipedia, and WordPress.

Advantages of PHP

  • PHP is a free, open-source server-side scripting language
  • A larger support community to help developers, programmers, and hiring teams.
  • It is perfect for large projects and socializing sites.
  • Perfect for building scripts, primarily web-based ones like- WCMS (Web Content Management Systems), because it is highly effective at communicating and accessing various database types.
  • PHP is highly scalable, which makes customization easier.
  • Experts to support in case of any issue or bug.
  • Low-cost software tool.
  • Powerful frameworks such as Laravel and Symfony make it even more popular.

Disadvantages of PHP

  • Not suited for building desktop applications/software.
  • PHP applications lag a bit more than other frameworks and languages.
  • It enables customization, which results in poor coding and sometimes hard bugs.
  • Approaching, managing, and fixing errors in PHP is poor.

What are Some Standard Criteria for Comparing PHP and ASP.NET?

Here are some parameters that help to understand ASP.NET and PHP-

Cost plays a crucial role when working on a large project. Regarding cost-effectiveness, PHP has a distinct advantage over ASP.NET as PHP is free, while ASP.NET comes with a web hosting fee.

A scalable technology is more flexible and covers a wide area. Compared to ASP.NET and PHP, ASP.NET can handle various web applications, which is impossible with PHP. ASP.NET is a more flexible language, and thus many developers choose it over PHP.

In PHP, scripts are executed faster than ASP.NET because PHP uses its memory, and performance depends on the level of interaction between the script, the database, and the server.

Moreover, PHP web application implementation takes the LAMP format, offering increased performance.

PHP programs run on their own memory space and do not require any other system resources, resulting in less execution time than ASP.NET. Whereas ASP.NET is a bit slow because it is built on a COM-based system that requires different storage areas.


PHP is hugely popular and used by almost 76.0% of all the websites whose server-side programming language we know, whereas ASP.NET is used by 7.6% of total websites whose server-side programming language we know, as per the recent stats.

Learning Curve:
If your organization has new developers, PHP is a better choice as it is easy to learn and understand for beginners, whereas ASP.NET is quite challenging to learn and needs time to master. Also, PHP has large community support to make your learning curve more smooth.

ASP.NET is the best pick for your organization if your applications primarily focus on security and functionality, whereas PHP is better for user interfaces, speed, and performance.

Market Share:

Top websites

PHP has a higher market share than ASP.NET since PHP is a free, open-source scripting language, whereas ASP.NET is a paid web application framework.

According to SimilarTech, there are 4,956,798 websites supported by PHP and 1,681,045 by ASP.NET. Overall, as shown by W3Techs, ASP.NET powers 2.73% of websites, and PHP powers 8.33% of websites.

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.
