Small PHP code problem with Quote marks within Quotes

For example in this PHP code I have:
else {
$videourl = "https://bill.ccbill.com/jpost/billingCascade.cgi?clientAccnum=939993&clientSubacc=<?=$set["ccbillsub"]?>&cascadeId=<?=$set["ccbillID"]?>";

I know the problem is the extra php commands which are messed up in the url:
<?=$set["ccbillsub"]?>
<?=$set["ccbillID"]?>

How best to display them as I'm getting unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING errors.

 

This should be better:

$videourl = "https://bill.ccbill.com/jpost/billingCascade.cgi?clientAccnum=939993&clientSubacc=" . $set["ccbillsub"] . "&cascadeId=" . $set["ccbillID"];

Code (markup):

 

You can also use the \ key for your quote marks in strings

For example:

echo 'Tizag - It\'s Neat!';

Code (markup):

 

$videourl = "https://bill.ccbill.com/jpost/billingCascade.cgi?clientAccnum=939993&clientSubacc={$set['ccbillsub']}&cascadeId={$set['ccbillID']}";

thanks guys, I tried the last one by danx10 as the code looked cleaner - worked great.

Anyone of you PHP coders want to tackle the Qype mouseover/php reveal that's been bugging me for weeks!?
