#32789 [NEW]: array_pop doesn't work correctly

From: php at thoftware dot de Operating system: Windows PHP version: 4.3.9 PHP Bug Type: Compile Failure Bug description: array_pop doesn't work correctly 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.
