I was setting up a new Mac and ran into this problem again, where a default PHP installation with brew
is missing a few important extensions. In this case, I wanted to get the imagick
extension loaded.
This guide assumes you have Homebrew installed and you’ve installed PHP with brew install php
.
Install Image Magick dependency
First, install imagemagick
itself. This is needed to get the source files you’ll use later to compile the PHP extension with.
This will also install the needed pkg-install
dependency.
Compile Imagick PHP extension with pecl
Next up, use pecl
to get the PHP extension compiled.
It will also auto-register itself in your php.ini and should now be available.

Note: if you run php-fpm, make sure you to restart your daemon to load the latest extension. Use brew services restart php
.
Permission denied errors?
You may get failed to open stream: Permission denied
errors when trying to perform a pecl
install. It shouldn’t happen, because Homebrew by default installs everything in local folders, but in case you do get that error you can prefix the commands with sudo
like this.

Imagemagick is very powerful tool to process images on command line. If you have multiple images, you can use imagemagick convert utility on Mac or Linux to create animation (animated gif). Here are steps to create animation using imagemagick.
Create multiple png images for animation
We will use 4 images to create animation. These 4 images are created by taking window screenshot on Terminal shell while typing “Hello Animation World”.

Animation with same delay 100 and infinite loop

delay 100 is equivalent of 100/100=1 fps (frames per second).
Here is the outcome animation gif image. Notice the equal delay after each frame in animation.
Animation with more delay after last image and infinite loop
We can repeat -delay param to change it for last image.
