PHP 4.0 Bug #7122: reference to array element problem

From: gargamel@wizard-labs.org Operating system: Linux PHP version: 4.0.2 PHP Bug Type: Scripting Engine problem Bug description: reference to array element problem Creating a reference to an array element prevents that particular element from being listed in a foreach-loop. Instead, the previous element in the array is processed twice. Simple PHP script to reproduce the problem: --------------- <?php $A = array( 'a' => 'A', 'b' => 'B', 'c' => 'C'); /* This works: */ foreach ($A as $y => $x) { echo "y=$y x=$x\n"; } /* This breaks: */ $x = &$A['b']; foreach ($A as $y => $x) { echo "y=$y x=$x\n"; } ?> ------------------- This results in the following output: --------------------- X-Powered-By: PHP/4.0.2 Content-type: text/html y=a x=A y=b x=B y=c x=C y=a x=A y=b x=A <== ERROR!! y=c x=C ------------------- Note: I think this is possibly related to bug id #6417 -- Edit Bug report at: http://bugs.php.net/?id=7122&edit=1
