如何将变量传递到php中的会话数组

Question

after executing query search.php ,multiple results appears with own info(title,description,url).

result_1,result_2,result_3......

when i click on url,next page final.php opens. how should i store that result info in variable and display it on final.php .
I tried session variables,but it only passes last result info ie result_3 to next page.

here's my code

search.php

  <?php
  session_start();
  $_SESSION['title'] = $title;
  $_SESSION['description'] = $description;
  $_SESSION['content_url'] = $url;
  $_SESSION['icon'] = $icon;
  ?>   

final.php

 <?php 
    session_start();
    $session_title  = $_SESSION['title'];
    $session_description = $_SESSION['description'];
    $session_url = $_SESSION['content_url'];
    $session_icon = $_SESSION['icon'];
  ?>

Make sure you put session_start(); on top of each file you were using the session variables.

To make a array session variable you can do something like this:

<?php
session_start();

$_SESSION["array"][] = array(
    "title"         => $title,
    "description"   => $description,
    "content_url"   => $url,
    "icon"          => $icon
);

echo "<pre>";
var_dump($_SESSION);
echo "</pre>";

# Optional clear session, remove line if you don't want to
session_unset($_SESSION);
?>

Above code will output something like this:

array(1) {
  ["array"]=>
  array(1) {
    [0]=>
    array(4) {
      ["title"]=>
      NULL
      ["description"]=>
      NULL
      ["content_url"]=>
      NULL
      ["icon"]=>
      NULL
    }
  }
}

In final.php you can check this by doing:

if(isset($_SESSION["array"])) {
    foreach($_SESSION["array"] as $result => $key) {
        echo $key["title"];
    }
}

I hope this will help you.
