PHP setting and looping associative array - php

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!

Answer 1

You need to check again how the foreach works. In your case, you can simply do the following:
foreach($_SESSION['products'] as $value) {
echo $value['name'];
echo $value['price'];
}

Answer 2

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'];
}

Answer 3

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