Re: [PHP] passing references multiple levels of function calls

[Chris Lee]

your close.

<?php

 function f_of_A($var)
 {
   $var +=1;
 }

 function f_of_B($var)
 {
   $var %=3;
 }

 function do_both($vara, $varb)
 {
   f_of_A(&$vara);
   f_of_B(&$varb);
 }

 $gvara = 12;
 $gvarb = 13;

 do_both(&$gvara, &$gvarb);

?>

the '&' goes in front of the variable being given, not in the function args.
