Descriptionresource pg_pconnect ( string connection_string)
pg_pconnect() opens a connection to a PostgreSQL database. It returns a connection resource that is needed by other PostgreSQL functions.
For a description of the connection_string parameter, see pg_connect().
To enable persistent connection, the pgsql.allow_persistent php.ini directive must be set to "On" (which is the default). The maximum number of persistent connection can be defined with the pgsql.max_persistent php.ini directive (defaults to -1 for no limit). The total number of connections can be set with the pgsql.max_links php.ini directive.
pg_close() will not close persistent links generated by pg_pconnect().
