title: php connection pooling mysql
body: <p>I am planning to use MYSQL. Is there a connection pooling extension available? Or what is the normal practice for connection? 
  Is this the one used in every where...</p>
  
  <pre><code>mysqli_connect("localhost", "xxx", "xxx", "test");
  </code></pre>
  
  <p>Do people use just normal <code>mysql_connect</code> or <code>pconnect</code>..? How better is <code>pconnect</code> and what setting should I do for PConnect?</p>
