ibase_connect

(PHP 3>= 3.0.6, PHP 4 , PHP 5)

ibase_connect --  Open a connection to an InterBase database

Description

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

Establishes a connection to an InterBase server. 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 and password can also be specified with PHP configuration directives ibase.default_user and ibase.default_password. charset is the default character set for a database. buffers is the number of database buffers to allocate for the server-side cache. If 0 or omitted, server chooses its own default. dialect selects the default SQL dialect for any statement executed within a connection, and it defaults to the highest one supported by client libraries.

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().

例子 1. ibase_connect() example

<?php
    $host
= 'localhost:/path/to/your.gdb';

    
$dbh = ibase_connect($host, $username, $password);
    
$stmt = 'SELECT * FROM tblname';
    
$sth = ibase_query($dbh, $stmt);
    while (
$row = ibase_fetch_object($sth)) {
        echo
$row->email, "\n";
    }
    
ibase_free_result($sth);
    
ibase_close($dbh);
?>

注: The optional buffers parameter was added in PHP 4.0.0.

注: The optional dialect parameter was added in PHP 4.0.0 and is functional only with InterBase 6 and up.

注: The optional role parameter was added in PHP 4.0.0 and is functional only with InterBase 5 and up.

注: 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).
