What are some common reasons for PHP scripts to work locally but not on a web server?

One common reason for PHP scripts to work locally but not on a web server is due to differences in server configurations. This could include missing extensions, different PHP versions, or different settings such as error reporting levels. To solve this issue, it's important to ensure that the server environment matches the local environment as closely as possible. 

// Check for required PHP extensions
if (!extension_loaded('mysqli')) {
    die('The mysqli extension is required for this script to run.');
}

// Check for PHP version compatibility
if (version_compare(PHP_VERSION, '7.0.0') < 0) {
    die('This script requires PHP 7.0.0 or higher to run.');
}

// Check for other server configurations
// Add any additional checks as needed
