How to unlink existing image file using php | unlink() function in PHP to delete a file

 You can use the unlink() function in PHP to delete a file. The function takes the path of the file as its argument and deletes the file at that location.

Example:

$file_path = '/path/to/image.jpg';

if (file_exists($file_path)) {

    unlink($file_path);

    echo "The file has been deleted successfully.";

} else {

    echo "The file does not exist.";

}

It's also a good practice to check if file exist before unlink it, because unlink() function returns false if file doesn't exist or it's not writable.
