#46596 [NEW]: Setting an associative array $var with the key $var ... unexpected behaviour

From: benjaminNOpickSPAM at web dot de Operating system: Linux PHP version: 5.2CVS-2008-11-17 (CVS) PHP Bug Type: Arrays related Bug description: Setting an associative array $var with the key $var ... unexpected behaviour Description: ------------ As the following lines are ok: $var = $var + 1; $var[trim($var2)] = ''; I expected PHP to first evaluate the $key-String ([$var]), then modify $var. So a line like: $var = 'a'; $var[$var] = 0; should work. Reproduce code: --------------- <?php $var = 'xxxxx'; $var[$var] = true; var_dump($var); ?> Expected result: ---------------- array(1) { ["xxxxx"]=> bool(true) } or a warning like: Warning: Cannot use a scalar value as an array Actual result: -------------- string(5) "1xxxx" Depending on what code was before it, or what was in $var before, the first character is not always '1'. -- Edit bug report at http://bugs.php.net/?id=46596&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=46596&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=46596&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=46596&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=46596&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=46596&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=46596&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=46596&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=46596&r=needscript Try newer version: http://bugs.php.net/fix.php?id=46596&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=46596&r=support Expected behavior: http://bugs.php.net/fix.php?id=46596&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=46596&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=46596&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=46596&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=46596&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=46596&r=dst IIS Stability: http://bugs.php.net/fix.php?id=46596&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=46596&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=46596&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=46596&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=46596&r=mysqlcfg
