The manual says about call_user_func_array():
"Note: Referenced variables in param_arr are passed to the function
by
a reference, others are passed by a value. In other words, it does not
depend on the function signature whether the parameter is passed by a
value or by a reference. "
array_multisort expects an array by reference, but when you use
call_user_func_array in your code its not a reference just a regular
variable.
This worked by accident in PHP 5.2.

Description:
------------
I just upgrade my php v to 5.3 and it appears this error.
this is my old script, and returns error like this
Reproduce code:
---------------
function fn_array_multisort()
{
$n = func_num_args();
$ar = func_get_arg(0);
if(!is_array($ar)){
return false;
}
for($i = 1; $i < $n; $i++){
$col[$i] = func_get_arg($i);
}
foreach($ar as $key => $val){
foreach($col as $kkey => $vval){
if(is_string($vval)){
${"subar$kkey"}[$key] = isset($val[$vval]) ?
$val[$vval] : '';
}
}
}
$arv = array();
foreach($col as $key => $val){
$arv[] = (is_string($val) ? ${"subar$key"} : $val);
}
$arv[] = $ar;
call_user_func_array("array_multisort", $arv);
return $ar;
}
Expected result:

Warning: Parameter 1 to array_multisort() expected to be a reference,
value given in /usr/local/nginx/html/fox/core/fn_common.php on line
2000

Actual result:

call_user_func_array("array_multisort", $arv);
this line might be the clue call_user_func_array("array_multisort",
$arv);
please help, thanks
