This bug has been fixed in CVS. Snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. Thank you for the report, and for helping us make PHP better. The reason : array_*diff() and array_*intersect() not clearing the fci cache before work Previous Comments: ------------------------------------------------------------------------ [2004-06-11 17:06:17] rodolfo at rodsoft dot org This problem apparently is in uasort. If you change uasort for, say, uksort (and make code changes accordingly), the problem disappears. ------------------------------------------------------------------------ [2004-06-11 08:32:38] rodolfo at rodsoft dot org Description: ------------ If you call uasort with one callback function and then call array_udiff with another callback function, this last call will use first's callback. If we first call array_udiff and then call uasort, everything goes well. Reproduce code: --------------- <? class p { public $x; function __construct($x){$this->x=$x;} } function a(&$a, &$b){return $a->x - $b->x;} function b(&$a, &$b){return $a->y - $b->y;} $p1 = array(new p(2), new p(1), new p(0)); $p2 = array(new p(0), new p(2), new p(3)); uasort($p1, 'a'); print_r($p1); echo "\n"; print_r(array_udiff($p1,$p2, 'b')); ?> Expected result: ---------------- Notice: Undefined property: p::$y in tst.php on line 8 Actual result: -------------- Array ( [2] => p Object ( [x] => 0 ) [1] => p Object ( [x] => 1 ) [0] => p Object ( [x] => 2 ) ) Array ( [1] => p Object ( [x] => 1 ) ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28739&edit=1
