Is there a function to make a copy of a PHP array to another?

I have been burned a few times trying to copy PHP arrays. I want to copy an array defined inside an obj

Answer 1

PHP will copy the array by default. References in PHP have to be explicit.

$a = array(1,2);
$b = $a; // $b will be a different array
$c = &$a; // $c will be a reference to $a
