Fatal error: Call to undefined function curl_init() in D:\Shiki\github\yii-clockwerk\test-app\CurlHelper.php on line 90

It (cURL) works in the browser but not when in console. I didn’t think that it was this simple to fix. The PHP CLI uses a different config file (php.ini) compared to the one used by WampServer/Apache. You can see the location of the config file being used by typing:

php --ini

Result:

Configuration File (php.ini) Path: C:\Windows
Loaded Configuration File:         C:\wamp\bin\php\php5.3.0\php.ini
Scan for additional .ini files in: (none)
Additional .ini files parsed:      (none)

You can then fix the curl problem by enabling it in the php.ini file being used. Make sure this is not commented out:

extension=php_curl.dll

First off, all credits go to this guy. I’m just listing the steps on how I did it in Windows 7 with PHP 5.3. Also, I tested this using WampServer but I believe it should work on any PHP install.

Install memcached

1. Download the Memcached Win32 library here: http://code.jellycan.com/memcached. Just get the Win32 binary (direct link). Extract the downloaded archive file in a directory (e.g. c:\memcached). There should be a memcached.exe in there.
2. Run a command prompt as an administrator. Some info on how to do that here.

3. Install memcached as a service. Go to the memcached directory, type and run:

   memcached -d install
   

   If you get an error saying “MSVCP71.dll is missing”, see this page for a solution.

4. Start the memcached service by running:

   memcached -d start
   

5. You can verify if memcached is running by executing this in the command line:

   wmic process get description, executablepath | findstr memcached.exe
   

   You should see a result list showing memcached.exe and its full path.

Install PHP Memcache extension (php_memcache.dll)

1. Chances are you don’t have php_memcache.dll in your PHP extensions yet. You can download a build of it here. Basu has noted in the comments that VC6 builds are no longer available from that link. You can download the correct build here.
2. The archive should contain php_memcache.dll. Extract the archive to your php extensions directory. On my system (WampServer), this was C:\wamp\bin\php\php5.3.0\ext.

3. Edit php.ini, add this line to enable the extension:

   extension=php_memcache.dll
   

   Or if you’re using WampServer, restart it and enable the extension through the WampServer system tray menu.

Test

Test the installation using the sample PHP code here: http://www.php.net/manual/en/memcache.examples-overview.php.
