How can PHP documentation resources like opendir(), readdir(), closedir(), and glob() be effectively utilized for file manipulation tasks?

To effectively utilize PHP documentation resources like opendir(), readdir(), closedir(), and glob() for file manipulation tasks, you can use opendir() to open a directory handle, readdir() to read the contents of the directory, closedir() to close the directory handle, and glob() to match files using patterns. 

// Open a directory handle
$dir_handle = opendir('path/to/directory');

// Read the contents of the directory
while (($file = readdir($dir_handle)) !== false) {
    // Perform file manipulation tasks here
    echo $file . "\n";
}

// Close the directory handle
closedir($dir_handle);

// Match files using patterns
$files = glob('path/to/directory/*.txt');
print_r($files);
