How can browser-specific behavior impact the functionality of PHP scripts, as seen in the case of Firefox vs. Internet Explorer?

Browser-specific behavior can impact the functionality of PHP scripts when certain functions or features are supported in one browser but not in another. To address this issue, developers can use conditional statements to detect the user's browser and adjust the script accordingly. For example, if a script relies on a specific JavaScript function that is only supported in Firefox but not Internet Explorer, the developer can provide an alternative solution for IE users. 

<?php

// Check if the user is using Firefox
if(strpos($_SERVER['HTTP_USER_AGENT'], 'Firefox') !== false){
    // Firefox specific code here
} else {
    // Code for other browsers
}

?>
