Returns a persistent connection to a database
( string database, string username, string password [, array options] )
Returns a persistent connection to an IBM DB2 Universal Database, IBM
Cloudscape, or Apache Derby database.
Calling db2_close() on a persistent connection always
returns TRUE, but the underlying DB2 client connection remains open and
waiting to serve the next matching db2_pconnect()
Note that you are strongly urged to only use persistent connections on
connections with autocommit turned on. If you attempt to combine
transactions with persistent connections, issuing
db2_commit() or db2_rollback()
against a persistent connection will affect every persistent connection
that is currently using the same underlying DB2 client connection. You may
also rapidly experience locking escalation if you do not use autocommit for
your persistent connections.
Returns a connection handle resource if the connection attempt is
successful. db2_pconnect() tries to reuse an existing
connection resource that exactly matches the
database, username, and
password parameters. If the connection attempt fails,
db2_pconnect() returns FALSE.
