<?php
function js_redirect($url, $seconds=5) {
echo “<script language=\”JavaScript\”>\n”;
echo “<!– hide code from displaying on browsers with JS turned off\n\n”;
echo “function redirect() {\n”;
echo “window.location = \”" . $url . “\”;\n”;
echo “}\n\n”;
echo “timer = setTimeout(’redirect()’, ‘” . ($seconds*1000) . “‘);\n\n”;
echo “–>\n”;
echo “</script>\n”;
return true;
}
js_redirect(http://blogulate.com,1); //Redirects to blogulate.com in 1 second.
?>
Eg Usage :
js_redirect(http://google.com,5); //Redirects to Google after 5 seconds.
