How can PHP beginners effectively learn to delete files programmatically in PHP?

To delete files programmatically in PHP, beginners can use the `unlink()` function. This function takes the file path as its parameter and deletes the file if it exists. It's important to check if the file exists before attempting to delete it to avoid errors. 

$file_path = "path/to/file.txt";

if (file_exists($file_path)) {
    unlink($file_path);
    echo "File deleted successfully.";
} else {
    echo "File does not exist.";
}
