Break Neck’s PHP script

Let’s ask Frank over in the server-side group to write us a PHP script to

look up customer addresses. Then you can send the customer’s phone

number to this script, and get the customer’s address as a response.

Hey, Frank, you’re good with PHP, right?

Yeah, sure. What do you need?

I’ve got a customer’s phone number from an order

form.You think you could write a script that gives me

that customer’s address based on their number?

In the book’s examples, look in the chapter02/breakneck directory,

and nd the lookupCustomer.php script. This is a PHP script that will

run without a database server; keep this le on your computer, or

FTP it to your web site—you’ll be using it in just a sec.

...then I can use JavaScript to update my HTML on the y.

No, I’m making an asynchronous request, so I won’t

need anything but the raw data...

Jim

Sure, just send over the phone number as a request

parameter. You want me to return their information

as part of a new HTML page?
