As there are 4 code-sniplets with 4 different results, I thought it
would be a good idea to show the results as comments with the
corresponding code. I don't think it would be more readable otherwise.

Description:
------------
array_pop() removes data from objects via a method.
Reproduce code:
---------------
class foobar {
var $cache = array();
function cache($j) {
if (!isset($this->cache[$j])) {
$this->cache[$j] = array(
'wert' => $j,
'text' => 'value: '.$j.'<br>',
'time' => 'set at '.date('h:i:s').'<br>',
);
}
return($this->cache[$j]);
}
}
$foobar =& new foobar();
$v = $foobar->cache(3);
echo $v['time'];
$v = $foobar->cache(3);
echo $v['time'];
$v = $foobar->cache(3);
echo $v['time'];
$v = $foobar->cache(3);
echo $v['time'];
/* returns as expected
set at 02:19:11
set at 02:19:11
set at 02:19:11
set at 02:19:11
*/
$foobar =& new foobar();
echo array_pop($foobar->cache(3));
/* returns as desired
set at 02:19:11
*/
$foobar =& new foobar();
echo array_pop($foobar->cache(3));
echo array_pop($foobar->cache(3));
echo array_pop($foobar->cache(3));
echo array_pop($foobar->cache(3));
/* returns as not desired
set at 02:19:11
value: 3
3
*/
$foobar =& new foobar();
$v = $foobar->cache(3);
echo $v['time'];
echo array_pop($foobar->cache(3));
/* returns as it should
set at 02:19:11
Fatal error: Only variables can be passed by reference in ...
*/
Seems that the first call with a method isn't recognized as being not a
variable =8-0.
Expected result:
----------------
see above
Actual result:
--------------
