Description:
------------
On the document page:
http://us2.php.net/manual/en/language.references.return.php
"& by function definition is optional in class methods."
Reproduce code:
---------------
<?
class reftest
{
var $var = "original";
function by_copy()
{
return $this->var;
}
}
print "By copy:\n";
$t = new reftest;
var_dump($t);
$c =& $t->by_copy();
$c = "copy";
var_dump($t);
Expected result:
----------------
According to docs, $c should be a reference to the class variable.
$t->c should have the value "copy" in the output from the last
var_dump. When an ampersand is prefixed on the function by_copy(), it
works as expected.
Actual result:
--------------
as demonstrated by the above code, a copy is returned.
