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.

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.
