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?

Solution 1

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.

Solution 2

I had to check the Server API from phpinfo() to decide which version to use

If It's Apache 2.0 Handler(mod_php) go with Thread Safe version

If It's CGI go with Non Thread Safe version

Solution 3

Unfortunately I do not run 64-bit version of PHP to test this, but for PHP 5.3 you can try this dll.

Dll from https://github.com/nicolasff/phpredis/downloads ( php_redis-2.1.3-5.2-vc6-ts-4350b2a.zip ), is working fine with PHP 5.2.17 (32-bit version).

I hope you will solve the problem.

Solution 4

I used XAMPP x86 / PHP 7.2.5 so I needed redis x86 and the directory is this: C:/xampp/php/ext/.
