extension in PHP scripts?

When working with PHP scripts, you may encounter the need to include or utilize external libraries or functionalities that are not built-in to PHP. In such cases, you can use PHP extensions to add these functionalities to your scripts. To include an extension in your PHP script, you can use the `extension` directive in your php.ini file or use the `dl()` function within your script to dynamically load the extension. 

// Example of including an extension in PHP script
// Method 1: Using the extension directive in php.ini
// Add the following line to your php.ini file
// extension=example_extension.so

// Method 2: Using the dl() function within your script
if (!extension_loaded('example_extension')) {
    if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') {
        dl('php_example_extension.dll');
    } else {
        dl('example_extension.so');
    }
}

// Now you can use functions and features provided by the 'example_extension' in your PHP script
