#37235 [NEW]: in_array returns true for non-existing elements

From: hodacsi at mailbox dot hu Operating system: Windows PHP version: 5.1.2 PHP Bug Type: Arrays related Bug description: in_array returns true for non-existing elements Description: ------------ The code speaks for itself: in_array founds a string in the array when it definitely should not. The code is kept simple - I've also used variables and verified variable types with gettype, so it's _should not_ be a matter of using strict parameter. Using the third 'strict' parameter it works as expected, even if it's definitely not a question of types. Tested under several PHP versions and platforms. Reproduce code: --------------- <?php $ids = Array ( '+36901112222', 'xxxxx', 'zzzzz' ); echo in_array( ' 36901112222', $ids ) ? 'found' : 'not found'; ?> Expected result: ---------------- It should not find the string and should echo "not found". Actual result: -------------- "found" -- Edit bug report at http://bugs.php.net/?id=37235&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=37235&r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=37235&r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=37235&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=37235&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=37235&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=37235&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=37235&r=needscript Try newer version: http://bugs.php.net/fix.php?id=37235&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=37235&r=support Expected behavior: http://bugs.php.net/fix.php?id=37235&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=37235&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=37235&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=37235&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=37235&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=37235&r=dst IIS Stability: http://bugs.php.net/fix.php?id=37235&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=37235&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=37235&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=37235&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=37235&r=mysqlcfg
