# ibase_pconnect

(PHP 5)

ibase_pconnect — Open a persistent connection to an InterBase database

### Description

resource ibase_pconnect ([ string `$database` [, string `$username` [, string `$password` [, string `$charset` [, int `$buffers` [, int `$dialect` [, string `$role` [, int `$sync` ]]]]]]]] )

Opens a persistent connection to an InterBase database.

ibase_pconnect() acts very much like ibase_connect() with two major differences.

First, when connecting, the function will first try to find a (persistent) link that's already opened with the same parameters. If one is found, an identifier for it will be returned instead of opening a new connection.

Second, the connection to the InterBase server will not be closed when the execution of the script ends. Instead, the link will remain open for future use ( ibase_close() will not close links established by ibase_pconnect()). This type of link is therefore called 'persistent'.

### Parameters

`database`

  The `database` argument has to be a valid path to database file on the server it resides on. If the server is not local, it must be prefixed with either 'hostname:' (TCP/IP), '//hostname/' (NetBEUI) or 'hostname@' (IPX/SPX), depending on the connection protocol used.

`username`

  The user name. Can be set with the ibase.default_user php.ini directive.

`password`

  The password for `username`. Can be set with the ibase.default_password php.ini directive.

`charset`

  `charset` is the default character set for a database.

`buffers`

  `buffers` is the number of database buffers to allocate for the server-side cache. If 0 or omitted, server chooses its own default.

`dialect`

  `dialect` selects the default SQL dialect for any statement executed within a connection, and it defaults to the highest one supported by client libraries. Functional only with InterBase 6 and up.

`role`

  Functional only with InterBase 5 and up.

`sync`

### Return Values

Returns an InterBase link identifier on success, or `FALSE` on error.
