What are the common pitfalls when migrating PHP scripts from one server environment to another?

Common pitfalls when migrating PHP scripts from one server environment to another include differences in PHP versions, server configurations, and directory structures. To avoid these issues, it is important to ensure that the new server environment is compatible with the PHP version used in the scripts, configure the server settings properly, and update any file paths or dependencies that may have changed.

// Example of updating file paths when migrating PHP scripts
$old_path = '/var/www/html/old_folder/file.php';
$new_path = '/var/www/html/new_folder/file.php';

if (file_exists($old_path)) {
    rename($old_path, $new_path);
    echo 'File path updated successfully!';
} else {
    echo 'File not found at the old path.';
}
