Php query from url

Question

I'm sure this has been answered on stack before but I don't know the proper terms to use to find my desired results.

I want to take a value in a url and input it into my php script. So if I goto:

http://mydomain/search.php='MYSEARCHQUERY'

The search.php would take the MYSEARCHQUERY as a value.

<?php 
$html=file_get_contents('http://anotherwebsite/MYSEARCHQUERY'); 
?>

Answer 1

The URL would be something like:

http://mydomain/search.php?query=MYSEARCHQUERY

and the PHP:

$html = file_get_contents('http://anotherwebsite/' . $_GET['query']);
