php in_array 和 str_replace

有这样的用法哦

 $allow_state_array_invoc = array('store_invoice','invoiceno','invoicerec','invoiceing');
         if (in_array($_GET['state'],$allow_state_array_invoc)) {

              $condition['invoice_state']  = str_replace($allow_state_array_invoc,
              array('0','1','2','3'), $_GET['state']);

         }
         else{
         $_GET['state'] = 'store_invoice';
         $condition['invoice_state'] = 0 ;
         }

O(∩_∩)O哈哈哈~很懒
