From: kraghuba at in dot ibm dot com Operating system: Linux, windows PHP version: 6CVS-2007-10-26 (snap) PHP Bug Type: Arrays related Bug description: array_intersect() emits unexpected no of notices when 2d array is passed as arg Description: ------------ when 2-d array is passed as argument to array_intersect() as first argument, it emits notices, which is expected because it expects an 1 dimensional array to be passed. The no. of notices that it emits when 2-d array is passed is more than expected number of. I suspect that this behavior is wrong. for example when the passed 2-d array has two sub arrays then two notices are expected but the number of emitted notices are more than 2 and that cannot be co-related. Please note that this behavior is only noticed on php6 with error_reporting = E_ALL Reproduce code: --------------- <?php $arr1 = array ( array(1, 2, "hello", 'world'), array(1, 2, 3, 4) ); $arr2 = array (1 => "one", 2 => "two", 3 => "three"); var_dump( array_intersect($arr1, $arr2) ); ?> Expected result: ---------------- Notice: Array to string conversion in %s on line %d Notice: Array to string conversion in %s on line %d Actual result: -------------- Notice: Array to string conversion in %s on line %d Notice: Array to string conversion in %s on line %d Notice: Array to string conversion in %s on line %d Notice: Array to string conversion in %s on line %d -- Edit bug report at http://bugs.php.net/?id=43109&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=43109&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=43109&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=43109&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=43109&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=43109&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=43109&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=43109&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=43109&r=needscript Try newer version: http://bugs.php.net/fix.php?id=43109&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=43109&r=support Expected behavior: http://bugs.php.net/fix.php?id=43109&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=43109&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=43109&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=43109&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=43109&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=43109&r=dst IIS Stability: http://bugs.php.net/fix.php?id=43109&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=43109&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=43109&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=43109&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=43109&r=mysqlcfg
