Previous Comments: ------------------------------------------------------------------------ [2016-05-27 21:01:23] albert at mediatribe dot net A notice within the compare function will also trigger this notice. For example: function test($a, $b) { return strnatcmp($a['name'], $b['name']); } $e = array( array( 'not-name' => 'a', ), array( 'name' => '', ), ); uasort($e, 'test'); (this is tested on PHP 5.3) ------------------------------------------------------------------------ [2016-01-03 14:46:18] white06tiger+PHPbug at gmail dot com Related To: Bug #71238 ------------------------------------------------------------------------ [2015-07-18 14:17:52] nikic@php.net This has been fixed in PHP 7. ------------------------------------------------------------------------ [2013-08-19 19:04:24] m at rtin dot so Sorry the use () isn't relevant, I forgot to remove it when simplifying my test case ------------------------------------------------------------------------ [2013-08-19 18:23:17] m at rtin dot so I ran into a similar issue, i'm sure it'll require the same patch as it's the backtrace causing the problem but worth noting it doesn't require an exception to trigger this, just a backtrace. $ cat usort.php <?php set_error_handler(function($errno, $errstr) { $bt = debug_backtrace(); var_dump($errstr); }); $arr = [1, 2]; usort($arr, function($a, $b) use ($arr) { trigger_error('test'); return $a > $b; }); $ php usort.php string(4) "test" string(59) "usort(): Array was modified by the user comparison function" ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
