Answer / md amanullah
mysql_connect opens a normal connections to mysql database.
mysql_pconnect opens a persistant connection i.e. if there
is any connection open in the script it will use that
connection not making a new connection each time. at very
high traffic enviornment mysql_connect provides better
performance.

Answer / aatit
The following are the differences -
- A new connection is established to the database by using
mysql_connect, where as mysql_pconnect opens a persistant
connection to the database.
- mysql_connect can be used to close the connection, where as
mysql_pconnect can not close the connection.
- Database is opened every time when the page is loaded by
mysql_connect. Whereas by using mysql_pconnect, database need
not be connected every time.
