ingres_charset

(PECL ingres >= 2.1.0)

ingres_charset — Returns the installation character set

说明

ingres_charset ( resource $link ) : string

ingres_charset() is called to determine the character set being used by the Ingres client, from II_CHARSETxx (where xx is the installation code).

Note:

You can override the value returned by using the function putenv(). Changing the value of II_CHARSETxx in a running Ingres installation can cause data corruption.

参数

link

The connection link identifier

返回值

Returns a string with the value for II_CHARSETxx or returns NULL if the value could not be determined.

范例

Example #1 ingres_charset() - Get the installation character set

<?php
$link = ingres_connect($database, $user, $password);

echo ingres_charset($link) . "\n";

ingres_close($link);
?>
