How can you efficiently loop through all POST variables in PHP to find specific patterns in their names?

When dealing with a large number of POST variables in PHP, you may need to loop through them to find specific patterns in their names. One efficient way to achieve this is by using a foreach loop to iterate over the $_POST array and check each key for the desired pattern using regular expressions. 

// Loop through all POST variables to find specific patterns in their names
foreach($_POST as $key => $value) {
    // Check if the key matches a specific pattern using regular expressions
    if(preg_match('/pattern/', $key)) {
        // Do something with the matching POST variable
        echo "Key: " . $key . ", Value: " . $value . "<br>";
    }
}
