location / {
    try_files $uri $uri/ $uri.php?$args;
}

location ~ \.php$ {
    include snippets/fastcgi-php.conf;
    fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
}


Explanation:

  1. The location / block checks for the existence of requested files or directories. It first tries to serve the requested URL as is ($uri), then it checks if a directory with the same name exists ($uri/), and finally, it appends .php to the URL and passes the arguments ($uri.php?$args) if the previous checks fail.
  2. The location ~ \.php$ block is responsible for handling PHP files. It includes the fastcgi-php.conf configuration snippet to ensure proper PHP-FPM handling. The fastcgi_pass directive specifies the PHP-FPM socket file, which may vary depending on your PHP version/configuration.
  3. The fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; line sets the path to the PHP script file based on the document root and the requested script name. This ensures that PHP-FPM knows which file to execute.
  4. The include fastcgi_params; line includes additional FastCGI parameters that are typically required by PHP-FPM.


By utilizing this Nginx configuration, the .php extension will be automatically removed from the URLs while allowing the server to correctly handle the PHP files.

How can we redirect URLs without the .php extension to the corresponding URL with the extension?

To redirect URLs without the .php extension to the corresponding URL with the extension, you can use an Apache .htaccess file or server-side scripting.

  1. Using .htaccess file (Apache server): Create or modify the .htaccess file in the root directory of your website if it doesn't already exist. Make sure the mod_rewrite module is enabled on your server. Add the following lines to your .htaccess file: RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}.php -f RewriteRule ^(.*)$ $1.php [NC,L] Save the .htaccess file and upload it to your server.
  2. Using server-side scripting (e.g., PHP): Add the following code to the top of your PHP file to check if the requested file with .php extension exists, and if not, redirect to the URL with the extension: Save the PHP file and upload it to your server.


Both approaches will redirect requests for URLs without the .php extension to the corresponding URL with the extension, ensuring a seamless user experience while maintaining proper URLs.


What does the .php extension in a URL indicate?

The .php extension in a URL indicates that the webpage is written in PHP (Hypertext Preprocessor) scripting language. PHP is a widely-used server-side scripting language that is primarily used for web development. When a web server receives a request with a .php extension, it recognizes that it needs to process the PHP code before sending the HTML response to the client's browser.


How can we open the nginx configuration file?

To open the nginx configuration file, you can follow these steps:

  1. Open a terminal or command prompt.
  2. Navigate to the directory where the nginx configuration files are located. The default location is usually /etc/nginx/. You may need root/administrator privileges to access this directory.
  3. Use a text editor to open the configuration file. Here are a few common options: Nano: sudo nano nginx.conf Navigate through the file using the arrow keys. Press Ctrl + O to save changes, and Ctrl + X to exit the editor. Vim: sudo vim nginx.conf Press i to enter insert mode, make changes, press Esc to exit insert mode, then type :wq and press Enter to save changes and exit Vim. GNU Emacs: sudo emacs nginx.conf Use the Emacs commands for editing, saving, and exiting the file. Sublime Text: sudo subl nginx.conf If Sublime Text is installed, it will open the file in a new window where you can make changes. Save the file and close the window to exit. VSCode: sudo code nginx.conf If Visual Studio Code is installed, it will open the file in a new window where you can make changes. Save the file and close the window to exit. Note: You can use any text editor you prefer.


Remember to use sudo (Super User) or have appropriate permissions to access and modify the nginx configuration file.

Are there any limitations to removing the .php extension using nginx?

Yes, there can be some limitations to removing the .php extension using Nginx. Some of the limitations include:

  1. File conflicts: If you have files that share the same name without the .php extension, there can be conflicts in serving the correct file. For example, if you have both "about.php" and "about" files, Nginx may have trouble distinguishing the correct one.
  2. URL conflicts: If you have URLs that conflict with existing directory names or other server configurations, removing the .php extension can cause conflicts. For example, if you have a directory named "about" and also want to serve "about.php" as "about", Nginx may have difficulty serving the correct resource.
  3. Directory indexing: By default, Nginx may not allow directory indexing when removing the .php extension. This means that if you access a directory without specifying a file, Nginx will not show the directory contents, resulting in a 403 Forbidden error.
  4. Cached resources: If you have previously accessed a PHP file with the .php extension, it might be cached by proxies or the client's browser. Removing the .php extension will not automatically update the cached resources, leading to potential issues with outdated content.


To mitigate these limitations, you can configure Nginx to handle such cases explicitly using location directives or by employing other techniques such as rewriting URLs, managing your file and directory structure appropriately, and ensuring proper cache management.


What happens if the requested URL without the .php extension does not exist?

If the requested URL without the .php extension does not exist, the web server will return a "404 Not Found" error. This means that the server could not find the requested resource or page.
