<?php
//Function to be called via call_user_func
function test(&$z)
{
echo "ok : " . $z . "\n";
}
// - 1 : With a local variable
//This should work, but...
$a = 1;
call_user_func('test',$a);//Warning: Parameter 1 to test() expected to be a
reference, value given
// - 2 : Giving a constant
//This should issue a warning but ...
call_user_func('test',2);//works fine. Output "ok : 2"
// - 3 : Base on a parameter
//This should work, but ...
function test3($p=3)
{
call_user_func('test',$p);//Warning: Parameter 1 to test() expected to be a
reference, value given
}
test3();
?>

----------------
ok : 1
<b>Warning</b>: Parameter 1 to test() expected to be a reference, value
given in

ok : 3

--------------
<b>Warning</b>: Parameter 1 to test() expected to be a reference, value
