O'Reilly is good for getting the facts. You could start with Programming PHP:
http://oreilly.com/catalog/9781565926103/
Check the O'Reilly PHP page for more resources, some printed:
http://oreilly.com/php/
If you're looking for books that specifically cover PHP's OO features,
there are lots of older books on pre-5.3 features, like Zandstra's PHP
5 Objects, Patterns, and Practice (2004):
http://www.amazon.com/PHP-5-Objects-Patterns-Practice/dp/1590593804/ref=sr_1_3?ie=UTF8&s=books&qid=1260652305&sr=8-3
Although if you're new to OOP you may want to read more general books
on the subject and then work your way back to the features available
in the version of PHP that you need to use.
In general, the best publishers I've found are O'Reilly, The Pragmatic
Programmers, Apress and Packt.
Best,

The thing is, the file_get_contents() fails the same way on local URLs -- that
is, web sites hosted on the same machine. Or even using the machine's own IP
address.

Ok Agreed.
Lets do one last chance to ensure that your system is allowing external
connections or connection to other systems in the network-
Use Curl to get in the file contents. Check your PHP that Curl is enabled.
Through phpinfo();
If the script output the google page then this means that there is nothing
that is stopping you form getting in the content externally.
<?php
// $str = file_get_contents ('http://www.google.com');
// echo $str;
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.google.co.in";); //
http://www.google.com
curl_setopt($ch, CURLOPT_HEADER, 0);
// grab URL and pass it to the browser
curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
?>

Well I would recommend jQuery for client-side ajax.
But if you're looking for an integrated solution for php on the server-side,
then you might want to check out Raxan for PHP - http://raxanpdi.com
