  <?php     if(empty($_post['count'])) {             $_post['count']='';          }         else {              $a=$_post['count'];          }         if(empty($_post['order'])) {             $_post['order']='';          }         else {              $b=$_post['order'];          }          if(empty($_post['search'])) {             $_post['search']='';          }         else {              $c=$_post['search'];          }         if($_post['count']=="count" && $_post['search']=="search" && $_post['order']=="order" )  {           echo  "i have count ,search , order" ;        }          else if($_post['order']=="order" && $_post['count']=="count" && $_post['search']!="search"  )  {            echo "i have order , count";         }         else if($_post['search']=="search" && $_post['count']=="count" && $_post['order']!="order"  )  {            echo "i have search , count";         }          else if($_post['search']=="search" && $_post['order']=="order" && $_post['count']!="count"  )  {            echo "i have search , order";         }                   else if($_post['count']=="count" || $_post['search']=="search" || $_post['order']=="order"  ) {           echo $_post['count'];           echo $_post['search'];           echo $_post['order'];        } ?>
