    $friends_inner=$_SESSION['friends'];
     echo "<pre>";
    print_r($friends_inner);
    echo "</pre>";

the output is above array

   for($i=0; $i<sizeof($friends_inner); $i++)
      {
     $selected_friend=$friends_inner[$i];
     $selected_friend_id=$selected_friend['id']; //array of ids
     $selected_friend_name=$selected_friend['name']; // array of names
     $name[$i]=$selected_friend_name;
      }

   $result=preg_grep('/^'.$var.'.*/', $name);//returns array matching with requested alphabet from textbox which work fine dispalaying names

     echo "<pre>";
    print_r($result);
     echo "</pre>";

here is the output

       Array
     (

     [555] => Fawad Khan
   )

as it its index is not sequentially so i am diong so to make it start from zero

     $final_result=array();
 $maxindex = max(array_keys($result));
      for($i=0;$i<=$maxindex;$i++){                 //returns array that start with zero
   if(isset($result[$i])){
     array_push($final_result,$result[$i]);
              }
     }
     echo "<pre>";
      print_r($final_result);
      echo "</pre>";

the result is

    Array
 (
[0] => Fazal Muhammad
[1] => Fawad Ahmad
[2] => Fayaz Zafar
[3] => Farhan Bogra
[4] => Farzana KArim Elora
[5] => Fahim Khan
[6] => Fahad Shams
[7] => Fazal Yazdan

[18] => Faisl Qureshi
[19] => Faisal Khan
[20] => Faiza Baloch
[21] => Fawad Khan

)

      $ids_of_result=array();       

now here is the big problem i want to extract all user ids from $friends_inner array which name equal to my $final_result array.i am doing so but the problem is that it goes upto last index i-e 22 and than through error that index 22 and ahead is not valid offset.how can i extract the ids from this $friends_inner which is my main array

开发者_开发技巧   for($j=0; $j<sizeof($friends_inner); $j++){
$selected_friend=$friends_inner[$j];
if($final_result[$j] == $selected_friend['name']){
    echo $selected_friend['name'];
    echo $selected_friend['id'];
array_push($ids_of_result,$selected_friend['id']); 
  //returns array of ids against result
   }

     }
     echo "<pre>";
     print_r($ids_of_result);
     echo "</pre>";

it result in Array ( )

     $counter=0;
      foreach($final_result as $key=>$value){

echo '<li onClick="fill(\''.$ids_of_result[$counter].'\');">'.$value.'</li>';
$counter++;
