Pass array from one page to another

Question

I have an array containing some values, say

arr[\'one\'] = \"one value here\";
arr[\'two\'] = \"second value here\";
arr[\'three\'] = \"third value here\";
         


        

Answer 1

The easiest way to do this would be to use the session to store the array from one page to another:

session_start();
$_SESSION['array_to_save'] = $arr;

More info on the sessions : http://php.net/manual/en/function.session-start.php

If you don't want to use session you can do something like this in your first page

$serialized =htmlspecialchars(serialize($arr));
echo "<input type=\"hidden\" name=\"ArrayData\" value=\"$serialized\"/>";

and in the other one you retrieve the array data like this :

$value = unserialize($_POST['ArrayData']);

Answer 2

home.php file

session_start();
if(!empty($arr)){
    $_SESSION['value'] = $arr;
     redirect_to("../detail.php");
}

detail.php

session_start();                    
if(isset($_SESSION['value'])){                           
    foreach ($_SESSION['value'] as $arr) {
        echo $arr . "<br />";
        unset($_SESSION['value']);
    }
}

Answer 3

If you dont want to use sessions, you can just include the page in the other file.

file1.php

<php
    $arr = array();
    $arr['one'] = "one value here";
    $arr['two'] = "second value here";
    $arr['three'] = "third value here";
?>

file2.php

<?php

    include "file1.php";

    print_r($arr);
?>

If the array is dynamically created and you want to pass it through GET or POST you should form the URL on the server side and redirect the user to the HTTP URL page instead of the php file.

So something like:

file1.php

<php
    $arr = array();
    $arr['one'] = "one value here";
    $arr['two'] = "second value here";
    $arr['three'] = "third value here";

    $redirect = "http://yoursite.com/file2.php?".http_build_query($arr);
    header( "Location: $redirect" );

?>

file2.php

<?php

    $params = $_GET;

    print_r($params['one']);
    print_r($params['two']);
    print_r($params['three']);
?>

You can pass the values by query parameters, too.

header('Location: detail.php?' . http_build_query($arr, null, '&'));

And you can get the array in the detail.php like this:

// your values are in the $_GET array
echo $_GET['one'];  // echoes "one value here" by your example

Be aware that if you pass values by GET or POST (hidden input field), they can be changed by the user easily.
