How can multiple <?php...?> sections in a script access the same script definition and functions?

To allow multiple <?php...?> sections in a script to access the same script definition and functions, you can use include or require statements to include a separate PHP file that contains the shared definitions and functions. This way, all sections of the script can access the same code without duplicating it.

// shared_functions.php
function myFunction() {
    // Function definition here
}

// script.php
include &#039;shared_functions.php&#039;;

// PHP code using myFunction
myFunction();
