php emailing an array - php

Question

I am trying to email the results held in an array ( shopping cart ) however when I send the email it is only the first name, price and qty which is displayed in the email and not any of the other names, prices or qty's. I am assuming there is something wrong with my loop but not sure where. Many thanks in advance. The results are placed in the comma_separated variable
$result= mysqli_query($conn, "SELECT * FROM testtable ");
// save product list as array
if (mysqli_num_rows($result) > 0) {
while($row = mysqli_fetch_object($result))
{
$sku = $row->ProductSKU;
$productInfo[$sku] = array();
$productInfo[$sku]['Name'] = $row->Name;
$productInfo[$sku]['Price'] = $row->Price;
$productInfo[$sku]['QTY'] = $row->QTY;
}
} else {
die ("ERROR");
}
$i=0;
$total=0;
// print the currently selected items
foreach ($_SESSION['cart'] as $sku => $quantity) {
$subtotal = $quantity * $productInfo[$sku]['Price'];
$total += $subtotal;
$array = array("Product:".$productInfo[$sku]['Name'],
"Units #".$productInfo[$sku]['Price'] ,
"Total:".number_format($subtotal, 2));
$comma_separated = implode("\n", $array);
}

You should probably change the following code:
// print the currently selected items
foreach ($_SESSION['cart'] as $sku => $quantity) {
$subtotal = $quantity * $productInfo[$sku]['Price'];
$total += $subtotal;
$array = array("Product:".$productInfo[$sku]['Name'],
"Units #".$productInfo[$sku]['Price'] ,
"Total:".number_format($subtotal, 2));
$comma_separated = implode("\n", $array);
}
into:
// print the currently selected items
$comma_separated = array();
foreach ($_SESSION['cart'] as $sku => $quantity) {
$subtotal = $quantity * $productInfo[$sku]['Price'];
$total += $subtotal;
$array = array("Product:".$productInfo[$sku]['Name'],
"Units #".$productInfo[$sku]['Price'] ,
"Total:".number_format($subtotal, 2));
$comma_separated[] = implode(', ',$array);
}
$comma_separated = implode("\n", $comma_separated);
Earlier you have created product array, imploded it using new line but finally you haven't saved this array in any other variable, so each time you run foreach loop you initialized $comma_separated variable again so the previous value wasn't there.
Now you should append $comma_separated to mail content, for example:
$mail_content .= $comma_separated;
