Erstmal muss es funktionieren. Dann kann man schauen, ob und was man umschreiben muss. Funktioniert ein Connect? Bekommst du Fehlermeldungen?

Leider bekomme ich da smit pdo_mssql nicht in meine phpinfo

***saftmeister*** · 30.12.11 20:55

Die Extension heißt intern pdo_sybase nicht pdo_mssql.

EDIT: Ich habe noch was anderes entdeckt, MS hat einen eigenen Treiber für PHP + SQLServer: http://www.microsoft.com/download/en...ng=en&id=20098

Habs gerade mal getestet, die Funktionen sind jedenfalls verfügbar. In phpinfo() sind die Erweiterungen pdo_sqlsrv und sqlsrv verfügbar.

Diese Beispiel-Datei funktioniert insofern, das die Funktionen existieren, ein Connect ist halt bei mir nicht möglich:
