PHP Search Engine

If your web server is using PHP, you can use PHP to include the search engine on your page. To use PHP remote include, you must have URL fopen wrappers enabled for your PHP module (which they are in the default configuration). Unlike the Javascript method, contents displayed by the PHP search engine are visible to robots. In its simplest form:

The dffget_affid=1001 tells the script that your affiliate id number is 1001. All you need to do is to replace the 1001 with your affiliate id number.
