php72-imagick 3.4.3 (new formula) (https://github.com/Homebrew/homebrew-php/pull/4267)

How can I do it?

Answer 1

It all changed back in April 2018 I think. Homebrew no longer acts as the package manager for PHP, so all the php-imagick and php-redis and php-other-extension stuff has gone and you are now supposed to manage PHP packages using pecl like everyone else does.

So, how to get Imagick under PHP? Note that Imagick and ImageMagick are two different things:

• ImageMagick is the entire ImageMagick suite
• Imagick is just the PHP binding

Here are the steps - if anyone knows better or any improvements, let me know via comment and I will update.

Step 1 - Delete anything likely to conflict

Before starting, it is best to clean up all the stuff that is broken or unneeded. Do as many of these as you are comfortable with:

brew rm php [email protected] [email protected] [email protected]
brew rm imagemagick

---

Step 2 - Update Xcode command line tools and get build packages

Make sure you have installed Xcode command-line tools with:

xcode-select --install

Go to AppStore and click on Updates and update any Xcode related packages - especially if you have recently upgraded macOS.

Install homebrew building tools:

brew install pkg-config

---

Step 3 - Install ImageMagick

Check what ImageMagick options you want with:

brew options imagemagick

I like to use:

brew install imagemagick --with-x11 --with-librsvg --with-openexr --with-pango
hash -r

but you may like vanilla install:

brew install imagemagick
hash -r

---

Step 4 - Install homebrew PHP

Next, install the homebrew version of PHP with:

brew install php
hash -r                    # Update bash's internal paths

Now, critically ensure you are running the correct homebrew PHP:

type php

If that tells you:

/usr/local/...anything.../php

you are running homebrew PHP and you can go to the next step.

If it tells you:

/usr/bin/php

you are running the Apple-supplied PHP. If that is what you want to run, ignore my entire answer which is predicated on you wanting to use homebrew PHP. If you get this answer but want to run homebrew PHP, your PATH is set incorrectly. You need to put /usr/local/bin before /usr/bin to pick up all homebrew packages ahead of Apple programs, i.e.

export PATH=/usr/local/bin:$PATH

This step gives you pecl - the PHP Package Manager - as well, since it is part of homebrew PHP.

Step 5 - Install Imagick

Now you can install Imagick with pecl:

pecl install imagick

If anything goes wrong, here are some related questions and answers...

Q1. How can I find where my php.ini file is?

Try any of these commands:

pecl config-get php_ini                  # I get "/usr/local/etc/php/7.2/php.ini"
brew info php
php -i | grep "Loaded Configuration"     # I get "Loaded Configuration File => /usr/local/etc/php/7.2/php.ini"

Q2. How can I find where pecl installs modules?

pecl config-get ext_dir                 # I get "/usr/local/lib/php/pecl/20170718"

Q3. How can I tell what PHP modules are loaded?

php -m

Q4. Why can't PHP find my module?

First locate your modules directory using Q2. I like to put that in the clipboard with:

pecl config-get ext_dir | pbcopy

Then edit the php.ini file from Q1. I use vi, so I would do:

vi "$(pecl config-get php_ini)"

Then find the line in that file that looks like this:

; Directory in which the loadable extensions (modules) reside.
; http://php.net/extension-dir

and, then (using the contents of your paste buffer) make the following line look like this (no semi-colon at the start):

extension_dir = "/usr/local/lib/php/pecl/XXXXXX"

on my machine XXXXXX is 20170718. If you get this right, any and all modules you install via pecl will be visible to your homebrew PHP.

Q5. How can I see all my PHP settings?

Check PHP configuration, versions and settings with:

php -i

Hope that helps!
