Answer Posted / praveen
mysql_pconnect() will maintain a persistent connection to
the database. whenever your script calls the connect to
database function, it first searches already existing
connections to the database and if exists it will use the
same connection to connect to the database, if not it will
open a new connection to the database. ie. Connection is
Persistent
where as mysql_connect() function will establish a new
connection whenever a connection to database needed, and
after executing the script, this function disconnects the
connection. ie. connection is not a persistent one.
mysql_pconnect() function is used where your site has a
Heavy Traffic and where as mysql_connect() function is used
when there is moderate/less traffic to your site.
