[PHP] passing references multiple levels of function calls

[Dennis Gearon]

I want to be able to do this:

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

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

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

$gvara=some_number;
$gvarb=some_other_number;

do_both( $gvara, $gvarb );

and have the original, global variables altered by the 'f_of_X'
functions.

The above structure and use of the '&' symbol DID NOT WORK, any ideas
why the
reference to the real contents did not get passed down?
