What are the differences between the ereg_* functions and the preg_* functions in PHP for handling regular expressions?

The main difference between the ereg_* functions and the preg_* functions in PHP for handling regular expressions is that the ereg_* functions are now deprecated and should not be used in new code. The preg_* functions provide more powerful and flexible regular expression handling capabilities and are the recommended choice for working with regular expressions in PHP. 

// Using preg_match to handle regular expressions in PHP
$string = "Hello, World!";
if (preg_match("/Hello/", $string)) {
    echo "Match found!";
} else {
    echo "No match found.";
}
