How can global variables impact the stability of PHP scripts in Apache?

Global variables can impact the stability of PHP scripts in Apache by introducing potential conflicts and unintended side effects. To mitigate this risk, it's recommended to limit the use of global variables and instead use local variables within functions or classes. By encapsulating variables within a smaller scope, you can reduce the likelihood of variable clashes and improve the overall stability of your PHP scripts. 

<?php

function myFunction() {
    $localVariable = "This is a local variable";
    
    // Use $localVariable instead of global $globalVariable
}

myFunction();

?>
