How can a loop be used to delete multiple files with similar filenames in PHP?
To delete multiple files with similar filenames in PHP, you can use a loop to iterate through the files and delete them one by one. You can use functions like `glob()` to retrieve a list of files matching a specific pattern, then loop through the list and delete each file using `unlink()` function.
$files = glob("path/to/files/prefix*"); // Get list of files with similar filenames
foreach($files as $file) {
unlink($file); // Delete each file
}
