[PHP] Test if URL is alive before including a remote JS

[Verdon Vaillancourt]

Hi :)

Given I have some content embedded on my page by calling a remote JS and
occasionally the URL for the remote script is down causing my page to be
slow or fail, can I use the following example as a means to test and timeout
the remote server and skip the embedded JS, if the remote server isn't
responding properly?

<?php
$fp = fsockopen ("www.theweathernetwork.com", 80, $errno, $errstr, 5);
if (!$fp) {
    echo "sorry, not available";
}     else {
    echo "<script language=\"JavaScript\" type=\"text/javascript\">
          <!-- var city = \"Muskoka_ON\"; //-->
          </script>
          <script language=\"javascript\" type=\"text/javascript\"
          src=\"http://www.theweathernetwork.com/weatherbutton/test.js\";>
          </script>";

    }
?>


TIA, verdon
