How can one ensure that all PHP files are uploaded correctly to a server?

To ensure that all PHP files are uploaded correctly to a server, one can use an FTP client to transfer the files, verify the file permissions are set correctly, and check for any errors during the upload process. Additionally, one can create a script to check the integrity of the uploaded PHP files by comparing their checksums with the original files. 

// Checksum verification script for uploaded PHP files
$uploaded_files = glob('path/to/uploaded/files/*.php');
$original_files = glob('path/to/original/files/*.php');

foreach ($uploaded_files as $uploaded_file) {
    $uploaded_checksum = md5_file($uploaded_file);
    
    foreach ($original_files as $original_file) {
        if (basename($uploaded_file) === basename($original_file)) {
            $original_checksum = md5_file($original_file);
            
            if ($uploaded_checksum !== $original_checksum) {
                echo "Error: Uploaded file " . basename($uploaded_file) . " does not match the original file.";
            }
        }
    }
}
