Curl and Search
Pretty much what it says on the tin.
How to use
Say you want to know how many times the string "foo" appears in the returned HTML of www.myspace.com. Visit: http://php-curl-tool.orchestra.io/?url=www.myspace.com&search=foo
UPDATE: This demo app, which was hosted on Orchestra, has been discontinued, but the tool still works. Download the tool and host it yourself. Much love, -A.
