#30298 [NEW]: $_POST variable not handling arrays properly

From: ross dot w at paradise dot net dot nz Operating system: Linux PHP version: 4.3.8 PHP Bug Type: Arrays related Bug description: $_POST variable not handling arrays properly Description: ------------ The $_POST variable does not return an array (eg. from a select multiple box) but instead returns the word "Array". $HTTP_POST_VARS and register globals do not have this problem. Reproduce code: --------------- <select multiple="multiple" name="test[]"> <option name="o1">Option 1</option> <option name="o2">Option 2</option> <option name="o3">Option 3</option> </select> User selects some of these and clicks Submit Expected result: ---------------- I would expect that these three cases should be equal on the PHP receiving side: $arr = $_POST["test"]; $arr = $HTTP_POST_VARS["test"]; $arr = $test; (On systems with register globals) Actual result: -------------- Instead: $arr = $_POST["test"]; $arr is a string with the word "Array" (incorrect) $arr = $HTTP_POST_VARS["test"]; $arr is the array of selected items (correct) $arr = $test; On systems with register globals, $arr is the array of selected items (correct) -- Edit bug report at http://bugs.php.net/?id=30298&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=30298&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=30298&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=30298&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=30298&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=30298&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=30298&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=30298&r=needscript Try newer version: http://bugs.php.net/fix.php?id=30298&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=30298&r=support Expected behavior: http://bugs.php.net/fix.php?id=30298&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=30298&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=30298&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=30298&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=30298&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=30298&r=dst IIS Stability: http://bugs.php.net/fix.php?id=30298&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=30298&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=30298&r=float MySQL Configuration Error: http://bugs.php.net/fix.php?id=30298&r=mysqlcfg
