I want to know the difference between mysql_connect() and mysql_pconnect()? A brief idea on this is welcome.

The following two links gives a detailed explanation on the difference between mysql_connect() and mysql_pconnect()

mysql_connect - opens a connection to the mysql server and closes when we use mysql_close

mysql_pconnect - this opens a constant connection to the mysql server which cannot be close by mysql_close and can be reused.
