What is the best way to determine if the required GDLib functions are available in PHP?

To determine if the required GDLib functions are available in PHP, you can use the `function_exists()` function to check for specific GDLib functions. This function takes the name of the function as a parameter and returns true if the function exists, and false otherwise. By checking for the required GDLib functions before using them in your code, you can ensure that your script will run smoothly without encountering any errors. 

if (function_exists('gd_info')) {
    // GDLib functions are available
    // Your code using GDLib functions here
} else {
    // GDLib functions are not available
    // Handle the situation accordingly
}
