Test case: <?php $foo = []; $foo[] = [ &$foo ]; array_search( $foo, $foo ); https://3v4l.org/3XMq5 Previous Comments: ------------------------------------------------------------------------ [2015-06-05 11:49:00] cmb@php.net This issue has been fixed as of PHP 5.3.15 and 5.4.5, see <http://3v4l.org/Y6ZKh>. ------------------------------------------------------------------------ [2013-06-08 09:58:38] marc-bennewitz at arcor dot de I have the same issue in a logger method stringify all values into a readable format (Zend\Log\Formatter\Base::normalize) which ever fail if the value contains a self referencing entry. It's simply not possible to check this case so in will result in an infinite loop or we get the fatal here described. AND on logging using the error handler there is a $context argument containing such a self reference :( ------------------------------------------------------------------------ [2012-06-03 21:40:25] ray dot burgemeestre at gmail dot com Didn't see your reply, that sounds good Felipe.., will check it out tomorrow.. thanks. ------------------------------------------------------------------------ [2012-06-03 21:36:33] ray dot burgemeestre at gmail dot com @carloschilazo of course removing the & fixes the error. You realize this is a bugreport right? My point is that I think the === operator should still return true or false. In this case true as $a and $a[0] are the same object. My testcase was a little ambiguous, shiranai7's version is better: $a = array(); $a[0] = &$a;. ------------------------------------------------------------------------ [2012-06-03 21:31:12] felipe@php.net I've committed a change that will return immediately true the comparison between same array. So, at least your '$a = array(&$a); $a === $a;' will works. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
