title: PHP+AJAX with MySQL - Query every 2 seconds, too many in TIME_WAIT
body: <p>I have a basic HTML file, using jQuery's ajax, that is connecting to my polling.php script every 2 seconds.</p>
  
  <p>The polling.php simply connections to mysql, checks for ID's newer than my hidden, stored current ID, and then echo's if there is anything new. Since the javascript is connecting every 2 seconds, I am getting thousands of connections in TIME_WAIT, just for my client. This is because my script is re-connecting to MySQL over and over again. I have tried mysql_pconnect but it didn't help any.</p>
  
  <p>Is there any way I can get PHP to open 1 connection, and continue to query using it? Instead of reconnecting every single time and making all these TIME_WAIT connections. Unsure what to do here to make this work properly.</p>
