I am having trouble with PHP extensions. I am trying to run a script and nothing happens then I checked my error log and here is what I got:

PHP Startup: Unable to load dynamic library 'C:\Program Files (x86)\PHP\ext\php_oci8.dll' - The specified module could not be found. in Unknown on line 0

same goes for following files:

 php_oci8_11g.dll
 php_pdo_oci.dll
 php_sybase_ct.dll
 php_com_dotnet.dll

every file except php_com_dotnet.dll was installed with PHP installation, all the files are enabled in php.ini configuration. After researching online I saw some people said that it has to be copied to system32 or sysWOW64 folder, which I did without success. Then I tried to register them using regsvr32 in cmd and I am getting error for every single file:

"The module name_of_the_module.dll failed to load"

I don't understand what am I doing wrong.

Server configuration is Windows 2008 R2 64bit, IIS7, PHP 5.3.27

I am getting this error when I start my xampp server.

C:\xampp\php\ext\php_oci8.dll' – %1 is not a valid Win32 application.

I downloaded php_oci8-2.0.8-5.6-ts-vc11-x86 and extracted php_oci8.dll into C:\xampp\php\ext directory.

Also, I downloaded instantclient-basic-nt-12.1.0.2.0 (32 bit version) and added the same to the PATH variable of windows.

C:\OracleBasicClient\instantclient-basic-nt-12.1.0.2.0\instantclient_12_1 added to PATH

Still, I'm getting this error and not sure why it is coming.

My windows is 64 bit.

PHP info (xampp)

System Windows NT 6.1 (Windows 7 Professional) i586
Compiler MSVC11 (Visual C++ 2012)
Architecture x86
Thread Safety enabled

What am I possibly doing wrong and how can I fix it?
