Question

I want to know how to pass more arguments to my array_walk..

$addresses = array('www.google.com', 'www.yahoo.com', 'www.microsoft.com');
$a = 'hey';
$b = 'hey';
array_walk($addresses, array($this, '_handle'), $a, $b); // $a and $b parameters doesn't get passed

private function _handle($address,$a, $b) {
       echo $address; // www.google.com
       echo $a // 012
       echo $b // 012
}

How do I pass parameters anyway? I have to pass more than 5 parameters.. please teach me.. thanks!

Answer 1

The third parameter is a mixed data type. If you have many parameters, I would suggest putting them into an Array – perhaps an associative array to name them. You’d then pull them back out of that param:

$addresses = array('www.google.com', 'www.yahoo.com', 'www.microsoft.com');
$params = array('first','second');
array_walk($addresses, array($this, '_handle'), $params);

private function _handle($address,$count, $params) {
       echo $address; // www.google.com
       echo $params[0]; // first
       echo $params[1]; // second
}
