What resources or tutorials would you recommend for someone looking to improve their understanding of regular expressions in PHP?

Regular expressions can be a powerful tool for pattern matching and string manipulation in PHP. To improve your understanding of regular expressions in PHP, I recommend checking out the official PHP documentation on regular expressions (https://www.php.net/manual/en/book.pcre.php) as a starting point. Additionally, websites like regex101.com can be helpful for testing and debugging regular expressions in real-time.

// Example code snippet demonstrating the use of regular expressions in PHP
$string = "Hello, World!";

if (preg_match("/Hello/", $string)) {
    echo "The string contains 'Hello'";
} else {
    echo "The string does not contain 'Hello'";
}
