检查windows上php版本

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 disabled for not thread safe

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

根据php版本参数，下载对应的 ImageMagick 和 php_imagick 模块

安装 php_imagick

1. 从php_imagick-….zip解压出php_imagick.dll，放到ext目录
2. 从ImageMagick-….zip解压出，文件名以CORE_RL or IM_MOD_RL开头的 DLL，放到 php.exe 所在的目录（这个目录应该已经配置到PATH）。
   或者，拷贝到其他目录，这个目录应该配置到PATH。
3. Add this line to your php.ini file: extension=php_imagick.dll
4. Restart the Apache/NGINX Windows service (if applicable)
