Installing PHP extensions

You may add additional PHP extensions that are not included out of the box with Herd, by installing them via Homebrew and pecl. The reason for this is that most of these extension have dependencies and can not be statically compiled, and therefore shipped, with Herd.

#

Adding extensions

To install additional extensions via Homebrew, you can compile them with the following commands. At first, Homebrew needs a base PHP for compiling the extension. This base PHP is only used for compiling the extension and Herd keeps using the static binaries, so you can still use the built-in Herd updater for PHP.

brew install php

Once PHP is installed via Homebrew, you may install the extension:

pecl install [extension-name]

This creates an [extension].so extension file that you can now activate and use with Laravel Herd.

On an M1/M2 Mac, the extension can be found at /opt/homebrew/lib/php/pecl. On an Intel Mac, it will be at /usr/local/lib/php/pecl.

#

Activating extensions

You may activate your custom extensions by editing your php.ini file. This file is located at ~/Library/Application Support/Herd/config/php/<version>/php.ini..

# Absolute path to the extension.so file
extension=/opt/homebrew/lib/php/pecl/20220829/[extension].so
