What are the potential reasons why a PHP script works locally with XAMPP but not when uploaded to a web server?

The potential reasons why a PHP script works locally with XAMPP but not when uploaded to a web server could be due to differences in server configurations, file paths, PHP versions, or missing extensions. To solve this issue, ensure that the server environment matches the local environment, check for any errors in the code, and verify that all necessary files and extensions are present on the web server. 

<?php
// Example code to check PHP version
if (version_compare(PHP_VERSION, '7.0.0') < 0) {
    echo 'PHP version 7.0.0 or higher is required';
    exit;
}

// Other code here
?>
