Hello,
I've upgraded from 5.1.1 to 5.1.2 and discovered the following
unexpected difference. Best shown by example.
<?
function getArray(&$arr)
{
$arr[] = 12;
}
getArray($p = array());
print_r($p);
?>
In php 5.1.1, the $p is passed correctly as reference and so returns
with the value 12 in its first element. I regard this as correct behaviour.
In php 5.1.2, the $p is passed by value. So on return, $p is still empty!
This can be fixed as follows:
$p = array();
getArray($p);
The following example works, as expected, in both 5.1.1 and 5.1.2.
<?
class A
{
public $i = 9;
}
function doAmend(A &$a) // & not required because class instance passed
by reference by default
{
$a->i += 30;
}
doAmend($b = new A);
print_r($b); // this prints the value of member i as 39 as
expected.
?>
