In link exchange with other web sites, I need to check daily whether my link is still on a remote URL, if the link is not on the remote page for 2 or 3 days, an email will be sent to me, how to do this with PHP? Or where can I find similar code script? Thanks for help!

    Depending upon how robust you want the check to be (e.g. do you want to know where in the data your link appears, or do you just want to know that it exists somewhere on the data returned by the remote URL?), you could just do a [man]file_get_contents/man and a simple [man]strpos/man check.

      Thank you for your help. I searched on hotscripts, and found the one named "free-link-exchange-form-and-automatically-back-link-checker" meets my requirement.
