What are the differences between using ereg and preg_match in PHP?

The main difference between ereg and preg_match in PHP is that ereg is a deprecated function while preg_match is the recommended and more powerful alternative. ereg is slower and less versatile than preg_match, which supports more advanced regular expressions. It is recommended to use preg_match for better performance and compatibility with newer PHP versions. 

// Using preg_match instead of ereg
$string = "Hello, World!";
if (preg_match("/Hello/", $string)) {
    echo "Match found!";
} else {
    echo "No match found.";
}
