4. Goto:

    http://pecl.php.net/package/imagick

    as of today, latest is 3.4.1 so I went to:
    http://pecl.php.net/package/imagick/3.4.1/windows

    My PHP version is: 5.6.18, and Thread Safety is Yes from
    Step #1, so I downloaded:
       5.6 Thread Safe (TS) x86
    I got: php_imagick-3.4.1-5.6-ts-vc11-x86.zip

5. Unzip and copy "php_imagick.dll" to the php extension folder:

    In my case:
    php_imagick.dll --> C:\UwAmp\bin\php\php-5.6.18\ext

    Note: this ZIP also contains dlls which other guides says
    to extract to the extension folder of apache.
    NO NEED TO DO IT. Step #3 has taken care of it.

6. Edit "php.ini" and add at the very end (could be 
    anywhere I suppose):

      [Imagick]
      extension=php_imagick.dll

      For super newbies: click the edit button in the UwAmp UI,
      "php_uwamp.ini" will open and edit it. It will be copied to
      the correct php.ini when UwAmp is restarted. I had 
      trouble at first since there are several php*.ini scattered 
      all over.

7. Restart Apache

8. Check PHPInfo
    scroll to section (or find): imagick    
    number of supported formats: 234

    If there is no "imagick" section or "supported format" is 0,
    something went wrong.

Hope this helps.

Took a long time to get it to work.

I initially followed:
http://php .net/manual/en/imagick.installation.php
but after installation, PHPInfo under imagick shows
number of supported formats = 0 

So I followed these steps, clobbered from various sources
to get it to work.

1. Open PHPInfo and check:
   Architecture = x86 or x64
   Thread Safety = yes or no

2. Download ImageMagick from:

   http://windows.php.net/downloads/pecl/deps/

   In my case I downloaded: ImageMagick-6.9.3-7-vc11-x86.zip
   because the Architecture under PHPInfo is x86
   as for vc11 or vc14
   search google for "visual c++ 11 runtime" or
   "visual c++ 14 runtime" and install it

3. Unzip and copy all dlls from the bin subfolder to the
    Apache bin directory. It's a bunch of CORE_RL_*.dll
    and IM_MOD_RL_*.dll plus a few other dlls.

    In my case, I installed UwAmp in C:\UwAmp, so:
    (from zip) bin/*.dll --> C:\UwAmp\bin\apache\bin

For windows users, I found this, hope this help

thank you Michele Locati

After 2 hours of looking for help from different documentation & sites, I found out none of them are complete solution.  So, I summary my instruction here:

1) yum install php-devel
2) cd /usr
3) wget http://pear.php.net/go-pear
4) php go-pear
5) See the following line in /etc/php.ini [include_path=".:/usr/PEAR"]
6) pecl install imagick
7) Add the following line in /etc/php.ini [extension=imagick.so]
8) service httpd restart

Hopefully, I can save other engineer effort & time.... Good luck!

For windows users, any stack: go to https://mlocati.github.io/articles/php-windows-imagick.html and check the filters for php version, thread safety and architecture. Download the appropriate package and follow install instructions on the site.

Just a note that the 'Ian Co' instructions for 'Installing ImageMagick on UwAmp for Windows' also works for XAMPP.  Just change the paths accordingly.

Addendum to Ian Co's "Steps to Install ImageMagick for Windows" specifically for Uniform Server Z and how to fix if you get an empty list of ImageMagick supported formats):

Thanks to Ian Co's comments above for setting me in the right direction.

My Uniform Server is installed to B:\UniServerZ, adjust the following steps to your specific installation.

If you've been messing around with a gazillion solutions like me, first delete any previous copies of imagemagick dll-s (i.e. IM_MOD_RL...dll-s, CORE_RL...dll-s) from your sysem, i.e. I had copied them to C:\Windows\system, B:\UniServerZ\core\php56, B:\UniServerZ\core\php56\extensions. 

1. Download ImageMagick-6.8.9-1-vc9-x86.zip from http://windows.php.net/downloads/pecl/deps/

Extract contents of bin folder to B:\UniServerZ\core\php56 (or whichever vresion of php you are using)

2. Download the appropriate imagick package from  http://pecl.php.net/package/imagick/3.1.2/windows
For me the right one was  php_imagick-3.1.2-5.6-ts-vc11-x86.zip , check phpinfo whether you need the thread-safe version or not and which architecture.

Extract php_imagemagick.dll ONLY (and not the other dll-s) to B:\UniServerZ\core\php56\extensions

Previously I had tried ImageMagick-6.9.3-7-vc11-x86.zip and ImageMagick-6.9.3-7-vc14-x86.zip but the dll-s here did not work, perhaps because Uniform Server was compiled using VC9? and these were compiled with later versions!? What a mess.

I had also tried creating a C:\ImageMagick and adding it to PATH user-level and to MAGICK_HOME system-level environment variables, but this proved unnecessary (although it also works).

Also, installing the windows binary releases from 
http://www.imagemagick.org/script/binary-releases.php#windows
was unnecessary (and might actually mess things up if windows tries those dll-s first).
