Foreach with session data

I don't have much knowledge, but I'm turning around, but I came across the following question, which seems to be simple in my view, but I found no answers or examples. If you can help me, please.

I get a list of 5 items on the paeg access.php

    <?php
session_start ();
foreach($followers as $value){

    $_SESSION['username_recente'] = $value['username'];
    $_SESSION['full_name_recente'] = $value['full_name'];
    $_SESSION['profile_pic_url_recente'] = $value['profile_pic_url'];
    $_SESSION['followed_by_viewer_recente'] = $value['followed_by_viewer'];
}

Return this to me:

Username: johndoe1
Fullname: john doe 1
profile_pic: http://....
followed: true

Username: johndoe2
Fullname: john doe 2
profile_pic: http://....
followed: true

I have 5 results of these.

With a simple echo, on that same page, I get the 5 items I want.

However, on the next page, index.php, there is only the first item on the list.

index.php

<?php
foreach ($_SESSION as $key => $value) {
print $key . '<br>';
print $value;
}

returns me only 1 result in index.php

Username: johndoe1
Fullname: john doe 1
profile_pic: http://....
followed: true

Am I using the functions correctly? I do not think so. Please help me.

Thanks to the help comments, they were very helpful, but I managed to solve the problem as follows:

Save session data with:

$_SESSION['array'] = $followers;

the next page, just:

foreach ($_SESSION['array'] as $value) {
// values...
}

tks a lot

You're only creating a single dimension with those keys, so for example $_SESSION['username_recente'] is overwritten each time through the loop and there will only be one. You'll need a multi-dimensional array of some sort. Here's an example similar to how database rows are returned:

foreach($followers as $key => $value) {
    $_SESSION[$key]['username_recente'] = $value['username'];
    $_SESSION[$key]['full_name_recente'] = $value['full_name'];
    $_SESSION[$key]['profile_pic_url_recente'] = $value['profile_pic_url'];
    $_SESSION[$key]['followed_by_viewer_recente'] = $value['followed_by_viewer'];
}

Then:

//required    
session_start();

foreach ($_SESSION as $array) {
    foreach($array as $key => $value) {
        print "$key : $value<br>";
    }
}

If you can use the same keys from $followers in $_SESSION then for the first page, just:

$_SESSION = $followers;
//or better
$_SESSION['followers'] = $followers;

Then on the next page loop $_SESSION['followers'].
