What are the advantages and disadvantages of using glob() function in PHP to list files in a directory?

The glob() function in PHP can be used to easily list files in a directory based on a specified pattern. This can be advantageous as it simplifies the process of retrieving files and allows for more flexibility in filtering the results. However, one potential disadvantage is that glob() may not work as expected on some systems or configurations, so it's important to test thoroughly. 

// List all PHP files in a directory using glob()
$files = glob('path/to/directory/*.php');

foreach($files as $file) {
    echo $file . "<br>";
}
