What are the benefits of using preg_match() over strpos() in certain situations in PHP?

When searching for a specific pattern or format within a string, using preg_match() in PHP can be more powerful and flexible than strpos(). preg_match() allows for the use of regular expressions to define complex patterns, while strpos() only looks for a simple substring match. This makes preg_match() a better choice when dealing with more intricate search requirements. 

$string = "Hello World";
$pattern = '/\bHello\b/';
if (preg_match($pattern, $string)) {
    echo "Pattern found in the string.";
} else {
    echo "Pattern not found in the string.";
}
