Hi,

I have found the following bug with the function call_user_func():

If the user function you are trying to call with 'call_user_func' requires any of its 
parameters to be passed by reference, PHP issues a warning stating that the function 
doesn't exist.

Example:

?php
function testme($param) {
 var_dump($param);
}

$func = testme;
$param = array(1, 2);

call_user_func($func, $param);

?

Result:

br
bWarning/b:  Unable to call testme() - function does not exist in bt.php/b on 
line b1/bbr

Regards,
Stefan Livieratos

if you take out the  in the testme argument list it works -
even weirder.

Actually, it doesn't seem that wierd to me ;)

the call_user_func() expects an array of parameters, therefore, the 
correct code would look like:

$func = testme;
$param = array(1, 2);

call_user_func($func, array($param));

But instead the code passes a constant value 1 to the first argument, 
and 1 cannot be passed by reference.  The error generated is kinda a 
bug, call_user_func() should emit a more general error message, but 
otherwise its not a real bug.

Never mind, I take this back ;)))

call_user_func  call_user_func_array() got confused in head.

Take a look at the call_user_*() thread ;)
