#46576 [NEW]: Adding to end of array - strange behaviour

From: geo at vzemibg dot com Operating system: CentOS PHP version: 5.2.6 PHP Bug Type: Arrays related Bug description: Adding to end of array - strange behaviour Description: ------------ I am submitting what in my view is uncorrect behaviour of the [] operator for arrays. It is a special case when the last element of the array is removed with unset() and then a new element is added using the arrname[] = xxxx syntax. Reproduce code: --------------- $teststring = "let's test this"; $testarr = explode(' ', $teststring); print_r($testarr);echo "<br />"; unset($testarr[2]); print_r($testarr);echo "<br />"; $testarr[] = 'new'; print_r($testarr); Expected result: ---------------- Array ( [0] => let's [1] => test [2] => this ) Array ( [0] => let's [1] => test ) Array ( [0] => let's [1] => test [2] => new ) Actual result: -------------- Array ( [0] => let's [1] => test [2] => this ) Array ( [0] => let's [1] => test ) Array ( [0] => let's [1] => test [3] => new ) -- Edit bug report at http://bugs.php.net/?id=46576&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=46576&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=46576&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=46576&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=46576&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=46576&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=46576&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=46576&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=46576&r=needscript Try newer version: http://bugs.php.net/fix.php?id=46576&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=46576&r=support Expected behavior: http://bugs.php.net/fix.php?id=46576&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=46576&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=46576&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=46576&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=46576&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=46576&r=dst IIS Stability: http://bugs.php.net/fix.php?id=46576&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=46576&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=46576&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=46576&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=46576&r=mysqlcfg
