Are there alternative methods or functions in PHP that can be used to delete files from a server besides the unlink() function?

If you are looking for alternative methods to delete files from a server in PHP besides the unlink() function, you can use the file system functions provided by PHP. One alternative method is to use the `unlink()` function in combination with `file_exists()` to check if the file exists before attempting to delete it. Another method is to use the `rmdir()` function to remove directories along with their contents. Additionally, you can use the `unlink()` function within a try-catch block to handle any potential errors that may occur during file deletion.

// Check if the file exists before attempting to delete it
$file = 'example.txt';
if (file_exists($file)) {
    unlink($file);
    echo "File deleted successfully.";
} else {
    echo "File does not exist.";
}

// Remove a directory and its contents
$directory = 'example_directory';
if (is_dir($directory)) {
    $files = glob($directory . '/*');
    foreach ($files as $file) {
        unlink($file);
    }
    rmdir($directory);
    echo "Directory deleted successfully.";
} else {
    echo "Directory does not exist.";
}

// Using try-catch block to handle errors
$file = 'example.txt';
try {
    unlink($file);
    echo "File deleted successfully.";
} catch (Exception $e) {
    echo "An error occurred: " . $e->getMessage();
}
