[PHP-DEV] filed passing by reference using call_user_func()

[KUBO Atsuhiro]

Hi, all.

I found problem of call_user_func() with passing by reference.

In test code, I expect that $test1 and $test2 and $test3 are
overwritten by MyFunction. However, $test2 is not overwritten.
Is this right behavior?

following test code:
<?php
$test1 = 'NG';
MyFunction($test2);

$test2 = 'NG';
call_user_func('MyFunction', $test2);

$test3 = 'NG';
call_user_func('MyFunction', &$test3);

print '$test1 is ' . $test1 . "\n";
print '$test2 is ' . $test2 . "\n";
print '$test3 is ' . $test3 . "\n";

exit();

function MyFunction(&$arg) {
    $arg = 'OK';
}
?>
