How can differences in server environments affect the functionality of a PHP script that works locally but not on a web server?

Differences in server environments such as PHP version, configuration settings, and extensions can affect the functionality of a PHP script that works locally but not on a web server. To solve this issue, ensure that the server environment matches the local environment by checking PHP version compatibility, adjusting configuration settings if needed, and installing required extensions. 

<?php
// Check PHP version compatibility
if (version_compare(PHP_VERSION, '7.0.0') < 0) {
    die('PHP version 7.0.0 or higher is required');
}

// Adjust configuration settings if needed
ini_set('display_errors', 1);
error_reporting(E_ALL);

// Install required extensions
if (!extension_loaded('mysqli')) {
    die('The mysqli extension is required');
}

// Your PHP script goes here
?>
