Re: [PHP-DEV] php5 method return reference error?

[Michael Walter]

Not sure I'm missing something, but I fail to see the problem: Doesn't 
PHP 5 use object references anyway? So function pla() { return new 
Foo(); } would return a reference anyway, instead of copying the object 
itself over?

So just removing & should fix the problem, as long as you're dealing 
with objects.

Cheers,
Michael

Howdy,
  I'm playing with php5 (from cvs), and came accross a strange error
that doesn't happen with php4.  Maybe someone can shed some light on
this for me?
I get the error
"Fatal error: Only variables or references can be returned by reference
in /home/waboring/devel/html/test.php on line 11"
Here is the php code

<?php

class foo {
    var $test = 0;
}
class bar {
    function &get() {
        //both of these fail
        //return new foo;
        return $this->_buildOBJ();
    }
    function &_buildOBJ() {
        $obj = new foo();
        $obj->test = 'worked';
        return $obj;
    }
}
$bar = new bar;
$foo = $bar->get();
echo $foo->test;
?>
This doesn't happen in php4.  
This seems to go away if I change the bar::get() method to

function &get() {
  $obj =& $this->_buildOBJ();
  return $obj;
}
   

This seems like a bug to me, since both cases the return value is a
reference of an object?
Thanks Walt
