php_redis.dll not working in windows

Question

I tried both the files from here: https://github.com/nicolasff/phpredis/downloads. I am using 64bit wampserver on windows 7 professional. It looks like apache is trying to load the file but somehow could not recognize it properly. This is what I see in the error log:

PHP Startup: Unable to load dynamic library 'D:/wamp/bin/php/php5.3.13/ext/php_redis.dll' - %1 is not a valid Win32 application.

Anyone faced similar issues? Do we have a working solution for this?

put the value of extension_dir in your php.ini. it should be something like C:\xampp\php\ext — undone
@ZiTAL I tried both the DLLs. Do you have a link for working dll? — Vikash
i wish this will be useful for you stackoverflow.com/questions/2001075/… — ZiTAL
I am not looking for a php library like predis. I wanted to have the extension working - specially for speed and session.save_path=redis. — Vikash
Is the path, D:/wamp/bin/php/php5.3.13/ext/php_redis.dll, proper? I wonder whether the forward slashes should be back slashes () instead, but if this is in line with how it's laid out in Apache's .conf file then this may be irrelevant. — Darth Continent

Just in case it can help someone, I managed to solve the error on PHP 7.1.12 installing the 32 bits DLL.

I was getting the error:

Warning: PHP Startup: Unable to load dynamic library '.../php_redis.dll'
not a valid Win32 application

But after installing the 32 bits version, the warning disappeared.

To know which architecture of XAMPP/WAMP are you using, visit the phpinfo() and look for the value "Architecture", it was for me on the fourth row, and as expected is had the value x86.
