PHP: Persistent Connection in a global variable

[CMMDB]

Hey!

So my Heliohost site is up and running smoothly, but not optimally. As visits increase, I've been getting errors regarding exceeding the number of allowed MySQL connections.So I looked up a snippet and adapted it to my needs. Question is, since I can't really see the amount of current MySQL connections in a way that I'm aware of, would this snippet theoretically do the job?Did I adapt it correctly? I include this wherever I need a db connection(Most every page) and call GetMyConnection().

 

(fatal_error() just dies with an image attached)

<?php
   if (!isset($g_link)) {
       $g_link = false;
   }

   function GetMyConnection()
   {
       global $g_link;
       if( $g_link )
           return $g_link;
       $g_link = @mysql_pconnect( 'localhost:3306', 'usr', 'pwd') or fatal_error("Could not connect to mysql server.<!--".mysql_error()."-->" );
       @mysql_select_db('db', $g_link) or fatal_error("Could not select database.<!--".mysql_error()."-->");
       return $g_link;
   }

?>
