Question

I populate the $_SESSION[‘products’] array from a file:

$myFile = '.\products.txt';
$handle = fopen($myFile, 'r');

while (!feof($handle))
{
    $prod = explode('|', fgets($handle));

    $_SESSION['products'] = array($prod[4] => array(
            'name' => $prod[0],
            'price' => $prod[1],
            'description' => $prod[2],
            'image' => $prod[3]));
}

Then I want to loop through it, printing all the names and prices:

foreach ($_SESSION['products'] as $prodID=>$value) {
  echo $_SESSION['products'][$value]['name'];
  echo $_SESSION['products'][$value]['price'];
}

But it doesn’t seem to work!

Your problem is, here you are overwriting the products array with every product, which means there will only ever be the last product present:

    $_SESSION['products'] = array($prod[4] => array(

Try appending to the array like:

$_SESSION['products'][$prod[4]] = array(
//                    ^^^^^^^^ set the key as the product ID here
        'name' => $prod[0],
        'price' => $prod[1],
        'description' => $prod[2],
        'image' => $prod[3]);

Also your foreach is wrong, try

foreach ($_SESSION['products'] as $prodID=>$value) {
  echo $value['name'];
  echo $value['price'];
}
