Are there any best practices recommended for managing file deletion processes in PHP applications?

When managing file deletion processes in PHP applications, it is important to ensure that proper permissions are set to prevent unauthorized deletion of files. Additionally, it is recommended to verify the existence of the file before attempting to delete it to avoid errors. Using functions like `unlink()` can help securely delete files in PHP applications. 

$file_path = '/path/to/file.txt';

if (file_exists($file_path)) {
    if (unlink($file_path)) {
        echo 'File deleted successfully.';
    } else {
        echo 'Error deleting file.';
    }
} else {
    echo 'File does not exist.';
}
