And yes, after first foreach you have a $value is a reference to the last element of the array. So when you do the second foreach (without unsetting $value), it rewrites value of array's first element. ------------------------------------------------------------------------ [2015-10-05 09:41:13] alex-dev at yandex dot ru Description: ------------ Array $test soured after use link in foreach. Test script: --------------- $test = array(1 => 1, 2 => 2, 3 => 3); foreach($test as $key => &$value) { } uasort($test, function($a, $b) { if($a > $b) return -1; else if($a > $b) return 1; else return 0; }); print_r($test); foreach($test as $key => $value) { } print_r($test); Expected result: ---------------- Array ( [3] => 3 [2] => 2 [1] => 1 ) Array ( [3] => 1 [2] => 2 [1] => 1 ) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=70639&edit=1
