Are there any best practices or recommendations for efficiently using preg_match in PHP code?

When using preg_match in PHP code, it is important to use the correct regular expression pattern to efficiently match the desired string. Additionally, it is recommended to use the preg_match function with the correct flags to optimize performance. It is also good practice to store the result of preg_match in a variable for further processing. 

// Example of efficiently using preg_match in PHP code
$string = "Hello, World!";
$pattern = "/^Hello/";
if (preg_match($pattern, $string, $matches)) {
    echo "Match found: " . $matches[0];
} else {
    echo "No match found";
}
