From: jasonp at quadco dot net Operating system: Linux 2.6.18 PHP version: 5.1.6 PHP Bug Type: Arrays related Bug description: array_search and in_array return unexpected values Description: ------------ If int 0 is used as an array_search or in_array needle and int 0 is not an element in the haystack, array_search and in_array will return int 0 and boolean true, respectively, instead of boolean false as expected. Reproduce code: --------------- $array = array('x', 'y', 'z'); var_dump(array_search(0, $array)); var_dump(in_array(0, $array)); Expected result: ---------------- var_dump and in_array should have spit out boolean(false) since int 0 is not in array $array. Actual result: -------------- int(0) bool(true) -- Edit bug report at http://bugs.php.net/?id=39153&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=39153&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=39153&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=39153&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=39153&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=39153&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=39153&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=39153&r=needscript Try newer version: http://bugs.php.net/fix.php?id=39153&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=39153&r=support Expected behavior: http://bugs.php.net/fix.php?id=39153&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=39153&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=39153&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=39153&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=39153&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=39153&r=dst IIS Stability: http://bugs.php.net/fix.php?id=39153&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=39153&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=39153&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=39153&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=39153&r=mysqlcfg
