Get All-Time Number of MySQL Queries

<?php
       $handle=@mysql_connect("localhost","root","");

       if (!$handle)
       {
               die("No connection to database");
       }

       echo 'Total number of all-time mysql-queries: '.getTotalNumberOfMySQLQuerys();

       //Returns integer-value of the total number of alltime mysql-calls that have been made
       function getTotalNumberOfMySQLQuerys()
       {
               //global mysql-status containing the number of querys has been renamed in newer versions of mysql
               $mysqlVersion=getMysqlVersion();

               //contact helper-function to receive the mysql-version
               if ($mysqlVersion()>=50002)
               {
                       $sql="SHOW GLOBAL STATUS LIKE 'Questions'";
               }
               else
               {
                       $sql="SHOW STATUS LIKE 'Questions'";
               }

               $result=@mysql_query( $sql );
               $row=@mysql_fetch_array( $result );
               return $row['Value'];
       }

       //helper function is needed to detect the exact mysql-version
       function getMysqlVersion()
       {
               $sql = 'SELECT VERSION() AS versionsinfo';
               $result = @mysql_query('SELECT VERSION() AS versionsinfo');
               $version = @mysql_result( $result, 0, "versionsinfo" );
               $match = explode('.',$version);
               return sprintf('%d%02d%02d',$match[0],$match[1],intval($match[2]));
       }
?>

Because the name of the global mysql-status-variable containing the number of queries changed in later versions of mysql, a helper-function is needed to detect the exact version of mysql you're running.
