Iterating through a $_session array

I have created a session array as follows

$_SESSION['memberInfo']['memberFirstName'] = ($first_name);
$_SESSION['memberInfo']['memberLastName'] = ($surname);
$_SESSION['memberInfo']['hash'] = ($hash);
$_SESSION['memberInfo']['templateSrc'] = ($newTemplateSrc);

in other pages where I'm trying to get the values from the array I have tried foreach and while loops without success, I can see the array in a var_dump

var_dump($_SESSION['memberInfo']);

which shows in console as 

array(4) {
  ["memberFirstName"]=>
  string(8) "Geoffrey"
  ["memberLastName"]=>
  string(6) "Turner"
  ["hash"]=>
  string(60) "$2y$10$YBE1tc.BK7yq6bBr/JAlWuN0H8xGdoNSAWzU4/zfd1r3v7jprNBD2"
  ["templateSrc"]=>
  string(61) "../userDirectory/558386500/html/Geoffrey_Turner_558386500.php"
}

in the pages where im trying to itterate the array I have tried using

foreach ($_SESSION['memberInfo'] as $name)
{
$first_name = $name['memberFirstName'];
}

the responce I get shows as

Warning: Illegal string offset 'memberFirstName'

which I believe suggests the itteration is reading an empty array

I can echo out the array using

foreach ($_SESSION['memberInfo'] as $key => $val) {
    echo "$key = $val\n";
}

which results in 

memberFirstName = Geoffrey
memberLastName = Turner
hash = $2y$10$YBE1tc.BK7yq6bBr/JAlWuN0H8xGdoNSAWzU4/zfd1r3v7jprNBD2
templateSrc = ../userDirectory/558386500/html/Geoffrey_Turner_558386500.php

but for the life of me I cannot seem to figure out how to get each of the array values individually and assign them to a variable

Your foreach makes no sense as you looping an trying to assing single variable too many times for no benefits. So this to be removed:

foreach ($_SESSION['memberInfo'] as $name =) {
    $first_name = $name['memberFirstName'];
}

as all you need is:

$first_name = $_SESSION['memberInfo']['memberFirstName'];

how to get each of the array values individually and assign them to a variable

You can use extract which extracts each value and assigns it to a variable.

extract($_SESSION['memberInfo']) this should create the following variables

$memberFirstName, $memberLastName, $hash, $templateSrc

Here is a demo http://ideone.com/XYpC7n
