Is there a function to make a copy of a PHP array to another?
...signed by reference. This means that:
$a = array();
$b = $a;
$b['foo'] = 42;
var_dump($a);
Will yield:
array(0) {
}
Whereas:
$a = new StdClass();
$b = $a;
$b->foo = 42;
var_dump($a);
Yields:
object(stdClass)#1 (1) {
["foo"]=>
int(42)
}
