PDO_INFORMIX DSN — Connecting to Informix databases
说明
The PDO_INFORMIX Data Source Name (DSN) is based on the Informix ODBC DSN string. Details on configuring an Informix ODBC DSN are available from the » Informix Dynamic Server Information Center. The major components of the PDO_INFORMIX DSN are:
- DSN prefix

The DSN prefix is
informix:. - DSN

示例 #1 PDO_INFORMIX DSN example using odbc.ini
The following example shows a PDO_INFORMIX DSN for connecting to an Informix database cataloged as Infdrv33 in odbc.ini:
$db = new PDO("informix:DSN=Infdrv33", "", "");
[ODBC Data Sources] Infdrv33=INFORMIX 3.3 32-BIT [Infdrv33] Driver=/opt/informix/csdk_2.81.UC1G2/lib/cli/iclis09b.so Description=INFORMIX 3.3 32-BIT Database=common_db LogonID=testuser pwd=testpass Servername=ids_server DB_LOCALE=en_US.819 OPTIMIZEAUTOCOMMIT=1 ENABLESCROLLABLECURSORS=1
示例 #2 PDO_INFORMIX DSN example using a connection string
The following example shows a PDO_INFORMIX DSN for connecting to
an Informix database named common_db using the
Informix connection string syntax.
$db = new PDO("informix:host=host.domain.com; service=9800;
database=common_db; server=ids_server; protocol=onsoctcp;
EnableScrollableCursors=1", "testuser", "tespass");

Example #2 PDO_INFORMIX DSN example using a connection string
To work properly, the DSN connection string must not have line breaks.
<?php
$conexion = new PDO("informix:host=host.domain.com; service=9800;
database=common_db; server=ids_server; protocol=onsoctcp;
EnableScrollableCursors=1", "testuser", "tespass");
$sql = "SELECT * FROM test";
$prep = $conexion->prepare($sql);
$prep->execute();
$result = $prep->fetchAll(PDO::FETCH_ASSOC);
var_dump($result);
?>
When connect to the Dynamic Informix Server, got this error log in apache's error log file:
[Wed Dec 30 12:44:11 2009] [error] [client 1.1.1.1] PHP Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE=HY000, SQLDriverConnect: -11005 [Informix][Informix ODBC Driver]Unspecified System Error = -11005.' in /opt/webroot/informix.php:5\nStack trace:\n#0 /opt/webroot/informix.php(5): PDO->__construct('informix:host=l...', 'username', 'password')\n#1 {main}\n thrown in /opt/webroot/informix.php on line 5
you should export correct INFORMIXDIR enviroment variable for root user and restart the web server.
and another error:
[Wed Dec 30 13:10:10 2009] [error] [client 1.1.1.1] PHP Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE=01S00, SQLDriverConnect: -11005 [Informix][Informix ODBC Driver]Invalid connection string attribute.' in /opt/webroot/informix.php:5\nStack trace:\n#0 /opt/webroot/informix.php(5): PDO->__construct('informix:host=l...', 'username', 'password')\n#1 {main}\n thrown in /opt/webroot/informix.php on line 5
you should let your connection string in one line, without line feed.
Bonjour
J'ai appliqué la procédure compilé, installé et charger le php_pdo_inkformix et j'ai utilisé la chaine de connexion suivant :
$bd = new PDO("informix:host=srvinf; service=1526;database=base; server=ol_test; protocol=onsoctcp;EnableScrollableCursors=1", "test", "test");
après éxécution du fichier connexion.php j'ai eu l'erreur :
- Fatal error: Uncaught exception 'PDOException' with message 'could not find driver' in C:\wamp\www\Tests\informix.php on line 5
-PDOException: could not find driver in C:\wamp\www\Tests\informix.php on line 5
Merci de m'assister svp.
