#36451 [NEW]: Array doesn't pop when array is created inside array_pop

From: epoc_32 at yahoo dot co dot ukXXX Operating system: Windows XP PHP version: 5.1.2 PHP Bug Type: Scripting Engine problem Bug description: Array doesn't pop when array is created inside array_pop Description: ------------ If you create an array inside array_pop(), expecting that array to be popped then it isn't even though the last element of that array is returned as expected. Creating the array on the previous line makes array_pop() behave as expected. This behaviour doesn't occur in PHP4.3.x on FreeBSD. I only noticed it when I upgraded to PHP 5.1.2 on my home WinXP machine though it's possible it was broken but I didn't notice it in 5.0.x Reproduce code: --------------- $a=array(0, 1, 2, 3, 4, 5); // Set array first. $offcut=array_pop($a); // Then pop array. $length=count($a); echo "<pre>Array offcut: " .$offcut."\nArray length: " .$length."\nLast element: " .$a[$length-1]."</pre>\n"; $offcut=array_pop($a=array(0, 1, 2, 3, 4, 5)); // Set and pop at the same time. $length=count($a); echo "<pre>Array offcut: " .$offcut."\nArray length: " .$length."\nLast element: " .$a[$length-1]."</pre>\n"; Expected result: ---------------- Array offcut: 5 Array length: 5 Last element: 4 Array offcut: 5 Array length: 5 Last element: 4 Actual result: -------------- Array offcut: 5 Array length: 5 Last element: 4 Array offcut: 5 Array length: 6 Last element: 5 -- Edit bug report at http://bugs.php.net/?id=36451&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=36451&r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=36451&r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=36451&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=36451&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=36451&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=36451&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=36451&r=needscript Try newer version: http://bugs.php.net/fix.php?id=36451&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=36451&r=support Expected behavior: http://bugs.php.net/fix.php?id=36451&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=36451&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=36451&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=36451&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=36451&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=36451&r=dst IIS Stability: http://bugs.php.net/fix.php?id=36451&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=36451&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=36451&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=36451&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=36451&r=mysqlcfg
