What happens when you press submit?

Page not found, error message, blank page etc etc?

tum_bin

when searching for any listed person name then its printing "{person} has 4 friends and common friends with Nandini, Mamun " and when search for any person which is not in list its showing totally blank page..

DaveRandom

You are missing a $, have several curly braces in the wrong places and a couple of other things. I am just debugging it now, but if you indent your code properly you will find it much easier to spot things like this.

I'll get back to you shortly

tum_bin

plz do something for me. im waiting gor Ur reply Sir.

<?php

  function searchPerson($person, $friends) {
    $direct = false;
    $found = false;
    if (in_array($person, array_keys($friends))) {

  print searchPerson($_GET['person'], $friends);

?>

Try that 🙂

DaveRandom

Just so you know, you don't need the curly braces in the strings to have the variables interpollated. Read this...

tum_bin

OH God! now another problem. when im searching for a person which is in list.. its printing "Rana is not in list".. and when im searching for a man which is not list its printing blank page .. grrrrrrrr.. bt thanx Sir for make code for me.

DaveRandom

Just realised it should probably be this:

<?php 

  function searchPerson($person, $friends) { 
    $direct = false; 
    $found = false; 
    if (in_array($person, array_keys($friends))) { 
      list($total, $common_friends) = commonFriend($person, $friends); 
      $direct = true; 
      $found = true; 
    } else { 
      foreach ($friends as $friend => $his_friends) { 
        if (in_array($person, $his_friends)) { 
          list($total, $common_friends) = commonFriend($friend, $friends); 
          $direct = false; 
          $found = true; 
          $friend_person = $friend; 
        } 
      } 
    } 
    if (!$found) {
      $output = "{$person} is not on the list";
    } else {
      $output = "{$person} "; 
      if ($direct) { 
        $output .= " has {$total} friends"; 
      } else { 
        $output .= " is {$friend_person}'s friend who has {$total} friends"; 
      } 
      if (isset($common_friends[0])) $output .= " and common friends with {$common_friends}"; 
    }
    return $output; 
  } 

  function commonFriend($person, $friends) { 
    $my_friends = $friends[$person]; 
    unset($friends[$person]); 
    $total_friends = count($my_friends); 
    $common_with = array(); 
    foreach ($friends as $friend => $his_friends) { 
      foreach ($my_friends as $my_friend) { 
        if (in_array($my_friend, $his_friends)) { 
          $common_with[] = $friend; 
        } 
      } 
    } 
    $common_with = array_unique($common_with); 
    $common_friends = ""; 
    if (count($common_with) > 0) { 
      $common_friends = join(", ", $common_with); 
    } 
    return array($total_friends, $common_friends); 
  } 

  $friends = array( 
    "Rana" => array("Pothik", "Zaman", "Tanmoy", "I****a"), 
    "Nandini" => array("Bonna", "Shakib", "Kamal", "Minhaj", "I****a"), 
    "Roni" => array("Akbar", "Anwar", "Khakan", "Pavel"), 
    "Liton" => array("Mahadi", "Pavel"), 
    "Mamun" => array("Meheli", "Tarek", "Zaman") 
  ); 

  print searchPerson($_GET['person'], $friends); 

?>

Don't forget to refresh the page instead of just changing the URL in the browser, so it isn't cached. Or you could add...

header("Cache-Control: no-cache, must-revalidate");
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");

before the print() call

tum_bin
