Install the ImageMagick PHP extension in Windows

In order to install the imagick PHP extension on Windows, you need to know the exact version of your PHP. To do this: open a command prompt and enter these commands:

  • Determine the PHP version:
    php -i|find "PHP Version"

  • Determine the thread safety
    php -i|find "Thread Safety"
    You’ll have enabled for thread safe or enabled for not thread safe

  • Determine the architecture
    php -i|find "Architecture"
    You’ll have x86 for 32 bits and x64 for 64 bits

Once you determined the above parameters, you have to download the dll of the PHP extension and the ImageMagick archive using the following table:

Version Thread Safe # of bits Estension ImageMagick
5.5 Yes 32
5.5 Yes 64
5.5 No 32
5.5 No 64
5.6 Yes 32
5.6 Yes 64
5.6 No 32
5.6 No 64
7.0 Yes 32
7.0 Yes 64
7.0 No 32
7.0 No 64
7.1 Yes 32
7.1 Yes 64
7.1 No 32
7.1 No 64

Once you downloaded the correct files:

  1. Extract from php_imagick-….zip to the ext directory the php_imagick.dll file of your PHP installation
  2. Extract from ImageMagick-….zip to the root PHP directory (where php.exe resides) the DLL files that start with:
    • CORE_RL_
    • IM_MOD_RL_
  3. Add this line to your php.ini file: extension=php_imagick.dll

To test if the extension works, you can run this PHP code:

$image = new Imagick();
$image->newImage(1, 1, new ImagickPixel('#ffffff'));
$pngData = $image->getImagesBlob();
echo strpos($pngData, "\x89PNG\r\n\x1a\n") === 0 ? 'Ok' : 'Failed';
