PHP Absolute link shows up as relative - Help!

[jmpetre]

OK, let me preface this by saying that I am not a PHP programmer, but I need to hack this code snippet that was given to me.  I have a php invoicing program running on my webserver, and I want to insert this piece of code into the invoices so my customers can pay via PayPal:

<?php 
    $amount = number_format($row->total_with_tax - $row->amount_paid, 2, '.', '');
    $link = urlencode("https://www.paypal.com/cgi-bin/webscr?cmd=_xclick&currency_code=USD&business=$companyInfo->primary_contact_email&amount=$amount&item_name=$row->name - Invoice $row->invoice_number");
    
    echo "<p>Pay the balance using PayPal - <a href='$link'>Click Here</a></p>";
    
    ?> 

 

The problem is, when I click on the link this generates, it tacks the link on like a relative link.  It looks like this:

http://www.abc.com:8080/index.php/invoices/view/https://www.paypal.com/cgi-bin/webscr%3Fcmd%3D_xclick%26currency_code%3DUSD%26business%3Dadmin@abc.com%26amount%3D0.00%26item_name%3DJane+Doe+-+Invoice+6

 

Is there something wrong with the code snippet?  Any help is greatly appreciated.  Thank you.

echo "<p>Pay the balance using PayPal - <a href='".$link."'>Click Here</a></p>";
