How can a PHP file be properly transferred from one server to another without causing functionality issues?

When transferring a PHP file from one server to another, it's important to ensure that all dependencies and configurations are also transferred to avoid functionality issues. One way to do this is to package the PHP file along with its dependencies into a zip file and then transfer and extract it on the new server. This ensures that all necessary files and configurations are maintained during the transfer process. 

// Example PHP code to package a PHP file and its dependencies into a zip file

$files = array('index.php', 'config.php', 'functions.php'); // List of files to include in the zip
$zipname = 'php_files.zip'; // Name of the zip file

$zip = new ZipArchive();
if ($zip->open($zipname, ZipArchive::CREATE) === TRUE) {
    foreach ($files as $file) {
        $zip->addFile($file);
    }
    $zip->close();

    echo 'Zip file created successfully';
} else {
    echo 'Failed to create zip file';
}
