    Extracting a number from a string ??


    I have a string like this:


    The bold element "example.com/" will stay constant and so will the "-" (dash or hyphen )
    immediately after the number. The other stuff can change a lot.

    I need to extract the number. In this case it is 18

    What would you say is the most efficient way to extract this using php ?
    I will use the number to find the record by it's id number in the db table.

    Many thanks.

    If you want to attract and keep more clients, then offer great customer support.

    Support-Focus.com. automates the process and gives you a trust seal to place on your website.
    I recommend that you at least take the 30 day free trial.

    PHP Code:
    $output preg_replace'/[^0-9]/'''$string );
