Sorry ... busy morning ... I misplaced the & for the reference. They
should be on the arguments on the function definiton, not the function
call.
<?php
function test( &$arg1, &$arg2 ){ // Note the "&" before the arguments.
$arg1 = "foo";
$arg2 = "bar";
}
$var1 = "";
$var2 = "";
test( $var1, $var2 );
?>
Sorry if I caused any confusion.
