Why is it recommended to use glob() for file searches in PHP instead of readdir()?

Using glob() is recommended for file searches in PHP because it simplifies the process by allowing you to specify a pattern to match files, whereas readdir() requires more manual handling of the directory iteration and file matching. Glob() also returns an array of file paths directly, making it easier to work with the results. 

// Using glob() to search for files in a directory
$files = glob('/path/to/directory/*.txt');

foreach($files as $file) {
    echo $file . "\n";
}
