From: rharrell at imagiclab dot com Operating system: RH Enterprise 4 PHP version: 5.2CVS-2008-01-18 (snap) PHP Bug Type: Unknown/Other Function Bug description: When using isset to check a variable returning true for an array key when str Description: ------------ If a variable is set to a string and isset() is used to check an array key for that variable it returns true. Reproduce code: --------------- $var="foo"; if(isset($var['ed'])) { //why are we in this section if $var is a string? if(is_array($var)) { // This doesn't happen echo "It's an array"; } else { // And yet this returns "f" echo $var['ed']; } } Expected result: ---------------- I would expect isset to return false; Actual result: -------------- isset returns true, because a check for any associative array index for the var will return the first character. -- Edit bug report at http://bugs.php.net/?id=43889&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=43889&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=43889&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=43889&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=43889&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=43889&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=43889&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=43889&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=43889&r=needscript Try newer version: http://bugs.php.net/fix.php?id=43889&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=43889&r=support Expected behavior: http://bugs.php.net/fix.php?id=43889&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=43889&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=43889&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=43889&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=43889&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=43889&r=dst IIS Stability: http://bugs.php.net/fix.php?id=43889&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=43889&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=43889&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=43889&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=43889&r=mysqlcfg
