#32484 [NEW]: in_array() doesn't return with an undefined array

From: edwin at mavetju dot org Operating system: FreeBSD 5.2.1 PHP version: 4.3.10 PHP Bug Type: Arrays related Bug description: in_array() doesn't return with an undefined array Description: ------------ I know this is wrong programming style, but in_array() hangs on this FreeBSD 5.2.1 box with PHP 4.3.10 when the haystack is an undefined array. It has the expected behaviour on FreeBSD 4.x and FreeBSD 5.3, it's just showing up in 5.2.1. This is an FYI bug report, it might be that you have had similar reports but never been able to put your fingers on the place where it hurted. Reproduce code: --------------- $a=array("foo"); if (!@in_array("bar",$a["foo"])) { echo "Not there\n"; } Expected result: ---------------- "Not there" Actual result: -------------- The interpreter hangs in the in_array() function. -- Edit bug report at http://bugs.php.net/?id=32484&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=32484&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=32484&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=32484&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=32484&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=32484&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=32484&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=32484&r=needscript Try newer version: http://bugs.php.net/fix.php?id=32484&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=32484&r=support Expected behavior: http://bugs.php.net/fix.php?id=32484&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=32484&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=32484&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=32484&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=32484&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=32484&r=dst IIS Stability: http://bugs.php.net/fix.php?id=32484&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=32484&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=32484&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=32484&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=32484&r=mysqlcfg
