PHP parse MYSQL after comma and output to html table - php

Question

Thank you all for you help! I received some phenomenal help about 17 days ago which saved my *!. I am still learning PHP and have run across a new problem. I have a MYSQL database field called "Tracking" this is a long text field in which we want to input tracking numbers (for shipping) separated by commas . We ship some times 20-50 individual boxes in the same order.
The following script outputs to an HTML table the number of boxes being shipped (EX Box 1 of 12, Box 2 of 12...etc) and then the value of the tracking number field. I need to modify it so it parses at the "comma" in the Tracking field and includes the tracking number for each box. So Box 1: Tracking Number "take first tracking number and end at comma", So Box 2: Tracking Number "take second tracking number and end at comma"....etc...does this make sense?
Please provide whatever help possible, would greatly be appreciated!
Script:
<?php
$q = intval($_GET['q']);
$con = mysqli_connect('***','***','***','***');
if (!$con) {
die('Could not connect: ' . mysqli_error($con));
}
mysqli_select_db($con,"db116223_wmi");
$sql="SELECT * FROM tbl_purchase_order WHERE purchase_order_id = '".$q."'";
$result = mysqli_query($con,$sql);
while($row = mysqli_fetch_array($result)) {
for ($i=0; $i<$row['product_quantity']; $i++) {
$my_val=1;
$x += 1;
echo "<table>";
echo "<tr>";
echo "<td width=400><br>Box $x of ". $row['product_quantity'] ." Tracking Number:". $row['Tracking'] ."</td>";
echo "</tr>";
echo "</table>";
}
}
mysqli_close($con);
?>

As jjonesdesign mentioned, you need to use explode to break the tracking number field up at each comma. explode creates an array of values, each split out of the Tracking field. Look below for the solution:
<?php
$q = intval($_GET['q']);
$con = mysqli_connect('***','***','***','***');
if (!$con) {
die('Could not connect: ' . mysqli_error($con));
}
mysqli_select_db($con,"db116223_wmi");
$sql="SELECT * FROM tbl_purchase_order WHERE purchase_order_id = '".$q."'";
$result = mysqli_query($con,$sql);
while($row = mysqli_fetch_array($result)) {
$myTracking = explode(',',$row['Tracking']); // get an array of tracking numbers. Array element starts with 0
for ($i=0; $i<$row['product_quantity']; $i++) {
$my_val=1;
$x += 1;
echo "<table>";
echo "<tr>";
echo "<td width=400><br>Box $x of ". $row['product_quantity'] ." Tracking Number:". $myTracking[$i] ."</td>";
echo "</tr>";
echo "</table>";
}
}
mysqli_close($con);
?>
