What are the advantages and disadvantages of using the glob() function in PHP to identify directories and files that match a certain criteria for deletion?

The glob() function in PHP can be used to identify directories and files that match a certain criteria for deletion, making it easier to target specific items for removal. However, one disadvantage is that glob() may not be as efficient for large directories with a high volume of files, as it retrieves all matching items at once. Additionally, there is a risk of accidentally deleting important files if the criteria used for deletion is not precise. 

$files = glob('/path/to/directory/*'); // Retrieve all files in the directory

foreach($files as $file){
    if(/* Add criteria for deletion here */){
        unlink($file); // Delete the file
    }
}
