Incorrect output when calculating totals - php

Question

I have a web page where i am able to export a .csv file that is readable on excel. The invoice pulls the data from my database to calculate the total and grand total using the following columns:
quantity, packing_price, courier_price
I have noticed that my code doesn't output the correct answer when the prices contains a '£' sound in front of it. Is there a way that i could make this work for both number and currency data types?
CODE:
$output2= "";
$sql2 = mysql_query("
SELECT j.date
, j.order_ref
, j.quantity
, j.packing_price
, j.dispatch_type
, j.courier_price
FROM Jobs j
WHERE j.order_type = 'Retail International'
AND j.confirmed = 'Yes';
");
$columns_total2 = mysql_num_fields($sql2);
$total3 = "Total";
for ($i = 0; $i < $columns_total2; $i++)
{
$heading2 = mysql_field_name($sql2, $i);
$output2 .= '"'.$heading2.'",';
}
$output2 .= $total3;
$output2 .="\n";
$sum2 = 0;
while ($row = mysql_fetch_array($sql2)) {
for ($i = 0; $i < $columns_total2; $i++) {
$output2 .='"'.$row["$i"].'",';
}
$qty2 = $row['quantity'];
$pack_price2 = $row['packing_price'];
$dispatch2 = $row['courier_price'];
$total2 = (($qty2*$pack_price2) + $dispatch2);
$total3 = $total2*1.2;
$output2 .= $total3;
$sum2 += $total3; // Add to overall total
$output2 .="\n";
}
Output:

Use this Code....
$output= "<table border='1' width='60%'><tr>";
$sql = " SELECT j.date ,
j.order_ref ,
j.quantity ,
j.packing_price ,
j.dispatch_type ,
j.courier_price
FROM Jobs j
WHERE j.order_type = 'Retail International'
AND j.confirmed = 'Yes' ";
$query = mysql_query($sql);
$total_columns = mysql_num_fields($query);
for ($i = 0; $i < $total_columns; $i++){
$heading = mysql_field_name($query, $i);
$output .= '<td>' . $heading . '</td>';
if(($i+1) == $total_columns) $output .= '<td>Total</td></tr>';
}
while ($row = mysql_fetch_array($query)) {
$total_price = 0;
$total_price =( ( $row['quantity'] * $row['packing_price'] ) +
$row['courier_price'] );
$total_price = $total_price * 1.2;
$timestamp = DateTime::createFromFormat('Y-m-d h:i:s',
$row['date'])->getTimestamp();
$output .= '<tr>';
$output .= '<td>' . date("d/m/Y", $timestamp) . '</td>';
$output .= '<tr>';
$output .= '<td>' . date("d/m/Y", strtotime($row['date']) . '</td>';
$output .= '<td>' . $row['order_ref'] . '</td>';
$output .= '<td>' . $row['quantity']. '</td>';
$output .= '<td>' . $row['packing_price'] . '</td>';
$output .= '<td>' . $row['dispatch_type'] . '</td>';
$output .= '<td>' . $row['courier_price'] . '</td>';
$output .= '<td>' . number_format($total_price, 2) . '</td>';
$output .= '</tr>';
}
$output .= "</table>";
echo '<br>' . $output;
