PHP SDK 2.1.0 With WAMP 2.5 and PHP 5.5

PHP SDK
2

Here I assume that you are using WAMP 2.5, and not 2.6 as you wrote in the message. Which is accessible at https://sourceforge.net/projects/wampserver/files/WampServer 2/Wampserver 2.5/. PHP extension 2.1.0 located at http://sdk-snapshots.couchbase.com/php/php_couchbase-2.1.0-5.5-zts-vc11-x64.zip. Unpacked extension into C:\wamp\bin\php\php5.5.12\ext\php_couchbase.dll and libcouchbase.dll somewhere in the PATH (In my case into C:\wamp\bin\php\php5.5.12\libcouchbase.dll and C:\wamp\bin\apache\apache2.4.9\bin\libcouchbase.dll).

Couple things here:

  1. wamp does not ship php5.dll (NTS version), but rather php5ts.dll (ZTS version), so you used incorrect archive
  2. when extension is loading, it looks up for libcouchbase.dll in the PATH or in current directory of the process so this DLL should be accessible there (for some reason OS keep removing libcouchbase.dll from C:\windows\system32.
  3. when registering extension for CLI mode, use C:\wamp\bin\php\php5.5.12\php.ini, and for apache, use C:\wamp\bin\apache\apache2.4.9\bin\php.ini. The real INI file location you can always findout during runtime:

CLI:

C:\wamp\bin\php\php5.5.12>php --ini
Configuration File (php.ini) Path: C:\Windows
Loaded Configuration File:         C:\wamp\bin\php\php5.5.12\php.ini
Scan for additional .ini files in: (none)
Additional .ini files parsed:      (none)

Apache httpd:

So if you did everything like I’ve described above, you should be able to successfully verify installation:

CLI:

C:\wamp\bin\php\php5.5.12>php.exe -i | find "couchbase"
couchbase
