Question

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 object to a global outside it.

Answer 1

Arrays are already assigned by copy. Just assign the array to a variable.

$array2 = $array1;

If you want them to reference each other (So the change in one array will affect the other) use the & character before the variable.

so $array2 = &$array1;
