To Check whether the internet connection is available while executing mysql queries

Function to be used in mysql:
mysql_ping(); //parameter will be the mysql_connect config properties.


Example:
$dbconn=mysql_connect('localhost','username','password');

if (mysql_ping ($conn))
{
    echo "connection is available";
}
else
{
   echo "connection is not available";
}


Note:
when internet connection is not available or breaks while queries executing,its better to close the mysql connection and restart again to set the mysql connection properly.

Example:

if (!mysql_ping ($conn)) {
   mysql_close($conn);
  $dbconn=mysql_connect('localhost','username','password');
   mysql_select_db('db',$dbconn);
}
