How can PHP be utilized to automate the process of deleting files based on specific criteria, such as age or file type?

To automate the process of deleting files based on specific criteria in PHP, you can use the `glob()` function to retrieve a list of files matching the criteria, and then loop through the list to delete each file. You can use functions like `filemtime()` to check the age of the file and `pathinfo()` to get the file type. 

// Define the directory path
$directory = '/path/to/directory/';

// Get a list of files matching specific criteria (e.g., files older than 7 days)
$files = glob($directory . '*.txt'); // Change the file type to match your criteria

// Loop through the files and delete them
foreach ($files as $file) {
    if (filemtime($file) < strtotime('-7 days')) { // Check if file is older than 7 days
        unlink($file); // Delete the file
        echo "Deleted file: $file\n";
    }
}
