    Hi,


    I was just looking at someone elses code and came across this:

    $request_uri = isset($_SERVER['REQUEST_URI']) ? $_SERVER['REQUEST_URI'] : "";
    Code (markup):
    What do the bit after the '?' and ':' mean?


    Thanks,

    Hodge :)

    Its a ternary operator. The example above will set $request_uri to the value of $_SERVER['REQUEST_URI'] if $_SERVER['REQUEST_URI'] was set, if it wasn't $request_uri will be set to an empty string.

    condition ? true-value : false-value;
