Well done for realising you need guidance.
PHP is purely reactive. It bursts into life to process a HTTP request
then dies until the next request. It only sends HTTP responses to
whatever it was that sent the HTTP request.
A grim hack might be meta refresh. A better solution is something other
than PHP.
