Bug #17569: array_push creates array if var is not set

From: tim@timcrider.com Operating system: Linux PHP version: 4.2.1 PHP Bug Type: Feature/Change Request Bug description: array_push creates array if var is not set Right now if you call array_push and the array parameter is not set, it gives the error Warning: First argument to array_push() needs to be an array in FILE on line NUM array_push should check to see if the variable is set or NULL. Only if it is NULL should it create a new array. If there is already something assigned to the var it should do nothing. -- Edit bug report at http://bugs.php.net/?id=17569&edit=1 -- Fixed in CVS: http://bugs.php.net/fix.php?id=17569&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=17569&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=17569&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=17569&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=17569&r=support Expected behavior: http://bugs.php.net/fix.php?id=17569&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=17569&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=17569&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=17569&r=globals
