Add a search in another domain

If you have a website on one domain and the ahcrawler instance runs on another one then the next snippet might be interesting for you. Here is a very simple example for a PHP website that requests an url on the ahCrawler instance to show the form and results. It uses the function file_get_contents for lowest requirements.

See the file integration/searchform.php on your AhCrawler instance - maybe you want to make a copy of it and restyle the form.

Very simple means: There are no protections yet against unwanted requests to the search form and no error handling.

Set $sCrawlerUrl to reference the php file with the search form on the AhCrawler instance.

Set values in the array $aDefaults.
