On a brew installed php7.2 on my MacOS 10.13.5 I get an error when running /usr/local/php5/bin/php from the command line:

Warning: PHP Startup: Unable to load dynamic library '/usr/local/php5/lib/php/extensions/no-debug-non-zts-20170718/imagick.so' (tried: /usr/local/php5/lib/php/extensions/no-debug-non-zts-20170718/imagick.so (dlopen(/usr/local/php5/lib/php/extensions/no-debug-non-zts-20170718/imagick.so, 9): Library not loaded: /usr/local/opt/imagemagick/lib/libMagickWand-7.Q16HDRI.5.dylib

Apparently you install php72-imagick differently these days as per this stack overflow answer: https://stackoverflow.com/a/50364995

I found I had to run the commands using sudo because my /usr/local couldn’t be written by my user and the pecl channel needs updating:

sudo pecl channel-update pecl.php.net
sudo brew update # check for new formulas
sudo brew upgrade # pull down the latest of everything for your brew environment
sudo brew install php # not needed if already installed
sudo brew install imagemagick # not needed if already installed
sudo pecl install imagick
# after the above you can then run php without all the missing imagick error messages
/usr/local/php5/bin/php -v
