How does PHP handle server-side execution and prevent the display of PHP code in the browser?

PHP handles server-side execution by processing PHP code on the server before sending the resulting HTML to the client's browser. To prevent the display of PHP code in the browser, PHP files should be stored in a directory that is not accessible to the public. This way, when a user requests a PHP file, the server processes the code and only sends the output to the browser.

// For example, store PHP files in a folder named 'includes' and use include or require to access them

include 'includes/myfile.php';
