PHP5中文手册·Open a connection to an InterBase database -- 追寻梦想＞编程乐园＞PHP 编程

说明

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

Establishes a connection to an InterBase server.

In case a second call is made to ibase_connect() with the same arguments, no new link will be established, but instead, the link identifier of the already opened link will be returned. The link to the server will be closed as soon as the execution of the script ends, unless it's closed earlier by explicitly calling ibase_close().

参数

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

返回值

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

错误／异常

If you get some error like "arithmetic exception, numeric overflow, or string truncation. Cannot transliterate character between character sets" (this occurs when you try use some character with accents) when using this and after ibase_query() you must set the character set (i.e. ISO8859_1 or your current character set).
