How can one ensure that their server supports the commands required for specific PHP requests?

To ensure that a server supports the commands required for specific PHP requests, you can use the `function_exists()` function in PHP to check if a certain function is available on the server. By checking for the existence of the required functions before using them, you can prevent errors and ensure that your code will run smoothly on the server. 

if (function_exists('required_function')) {
    // Code that uses the required function
} else {
    echo 'This server does not support the required function.';
}
