PHP - ImageMagick

ImageMagick is a powerful library to manipulate images, a PHP extension needs to be installed using Pecl. We always need to switch to every PHP version and install the package for that specific version.

Install ImageMagick extension

First install the brew ImageMagic package:

brew install imagemagick

Then install the php extension for every installed PHP version. The installation will ask you what the ImageMagick location is, hit enter to let the installer autodetect that location.

Please provide the prefix of Imagemagick installation [autodetect] : <enter>

Install ImageMagick for each installed PHP version:

sphp 8.4 && pie install imagick/imagick
sphp 8.5 && pie install imagick/imagick

This will automatically add the extension to php.ini.

Warning

It is possible that the extension for PHP 8.5 can not be loaded by default from the installed directory. You can fix this by altering the extension path in php.ini

vi $(brew --prefix)/etc/php/8.5/php.ini

The installation location of the zend extension is displayed on the screen after the pecl package is compiled. Copy it and use it on top of php.ini:

extension="/opt/homebrew/Cellar/php/8.5.4/pecl/20240924/imagick.so"

Update ImageMagick extension

These steps are only required when ImageMagick is updated with an existing PHP installation.

When ImageMagick is updated (through homebrew) PHP will start throwing errors since its Imagick module is compiled against an older version.

First edit the php.ini config files and remove the line extension="imagick.so".

vi $(brew --prefix)/etc/php/8.4/php.ini
vi $(brew --prefix)/etc/php/8.5/php.ini

Reinstall ImageMagick for all PHP versions:

sphp 8.4 && pie install imagick/imagick --force
sphp 8.5 && pie install imagick/imagick --force
