I have the following function:

function clean_form( &$from_check ) {
if(is_array($from_check)){
array_walk(&$from_check,'clean_form');
return;
} else {
$value = str_replace(array("\r","\n","Content-Type:"),"",$from_check);
}

When I call this function I get the following warning:

Warning: Call-time pass-by-reference has been deprecated - argument passed
by value; If you would like to pass it by reference, modify the declaration
of array_walk(). If you would like to enable call-time pass-by-reference,
you can set allow_call_time_pass_reference to true in your INI file.
However, future versions may not support this any longer.

In the PHP doc it shows referencing the array argument "by reference"; i.e.
'&' , but the runtime says this is a "no go". Then how am I supposed to use
array_walk?

TIA,
