I have downloaded php_imagick-3.4.3-5.6-ts-vc11-x64.zip
from there
Unzip and copy php_imagick.dll
to the c:\wamp\bin\php\php5.6.25\ext
(I'm using PHP version 5.6.25)
Then I have added extension=php_imagick.dll
in the wamp\bin\php\php5.6.25\php.ini
restarted server and go to the PHPInfo. imagick section did not appear
Then I added extension=php_imagick.dll
in the wamp\bin\apache\apache2.4.23\bin\php.ini
have restarted server and got the same result.
