I have a huge problem. I couldn't solve it alone and I didn't find anything like this in the internet, either.
I downloaded the instantclient_11_2 and put it in the C:\xampp_new\php directory. Also I uncommand the line "extension=php_oci8_11g.dll" in the php.ini. Further more I had an older version of XAMPP so i took the "php_oci8.dll" and "php_oci8_11g.dll" from there and put it in the directory C:\xampp_new\php\ext.
My problem is, that when I uncommand the line "extension=php_oci8_11g.dll" and start apache an error windows pops up, which says: "The procedure entry point php_checkuid could not be located in dynamic link library php5ts.dll.". After pressing the "OK" button, another Warning window pops up which say: "PHP Startup: Unable to load dynamic library 'C.\xampp_new\php\ext\php_oci8_11g.dll' ' - The specified procedure could not be found.
Can someone please explain me, how to setup all things right, because when I command the line "extension=php_oci8_11g.dll" no error occured, but I needed because I have to make a databaseconnection.
Thank you and sorry for my english. If you have any question please ask me, to solve the problem together.
