Testing to see if a website is online with php?

Im looking to create a simple php script that "pings" a website to see if it is online and returns a response of either up, or down.

Anyone have any suggestions on how to go about this?

    You can use CURL, fsockopen() or even file_get_contents(). Or, you can run a command line ping using exec.

    For a real simple ping you can try this, it will simply return the amount of time to establish a connection to the host.

    Code:
    <?php

 = microtime(true);
 = fsockopen(, , , , );
 = microtime(true);

if (!) {
//site is down
 = FALSE;
} else {
//get response time
fclose();
 = ( - ) * 1000;
 = floor();

    Curl is best (the 'proper' way of doing HTTP requests via PHP0, but fsockopen is nice and easy to use
