Last week, Hans Puac, a colleague of mine, wrote a small guide into our internal company chat on how to migrate your local PHP environment on macOS to the new Homebrew version 1.5.*. The guide helped a lot of other engineers inside trivago.
I thought it might help more people from the internet. I asked Hans if I am allowed to share it, and he approved. So kudos belongs to him.
Update (July 2021): Homebrew project structure changed
Due to a new homebrew / tap structure, this article might not be up to date anymore. Please check out the latest state of the PHP Homebrew formula.
Here we go:
With Homebrew v1.5.0 the tap
homebrew/php got deprecated.
They migrated it to
homebrew/core, but this is changing the installation process completely.
If you want to migrate:
Remove your currently installed PHP packages. This is not 100% necessary, but I wanted to have it clean.
You can check what packages are installed via
brew list | grep php, for example, and remove via
brew remove MYPACKAGE.
Check for leftovers in
/usr/local/etc/php/ and remove if necessary.
Untap the deprecated repo
brew untap homebrew/php.
You can check your taps with
I also had some other taps that I directly untapped as well because those were deprecated:
$ brew untap homebrew/science $ brew untap homebrew/versions
$ brew update
3. Install PHP
Install PHP via
$ brew install [email protected]
4. Verify Installation
Before we continue, we want to ensure that the
php --ini and
pear config-show | grep php.ini and check if everything is pointing to the right
PHP version and that no warnings are displayed.
If you encounter any problems, check the Troubleshooting section below.
5. Install Extensions
intl is now already built-in.
Install all other required extensions via PECL (gets installed together with PHP).
Installation via pecl requires autoconf (
brew install autoconf):
pecl install xdebug pecl install redis pecl install apcu pecl install memcached pecl install imagick
Particular version of an extension
If your app depends on a particular version of an extension, e.g. redis in v3.1.6
specify the version explicitly via
pecl install redis-3.1.6.
If you rely on the SNMP Extension, I have to disappoint you right now. This extension is, state of now (2018-04-10), not part of this PHP build:
SNMP was excluded from the build because it crashes Apache.
To make some disk space accessible, you may remove old versions of packages by executing
brew cleanup -s.
Wrong PHP Version is displayed
php --version displays the wrong PHP version, try to open a new terminal window. The PATH variable got
adjusted during the PHP installation and might not be loaded in your current terminal session.
If the old version is still displayed, check your PATH (
echo $PATH) and ensure that
/usr/local/bin/ comes before
/usr/bin/ or uninstall the other PHP version if the PATH was already set properly. The commands
ls -la $(which php) and
brew list | grep php might help you find out where that version is coming from.
PEAR configuration is pointing to the wrong
pear config-show | grep php.ini is pointing to the wrong
php.ini file, you can overwrite it with
pear config-set php_ini /MY/RIGHT/PATH/php.ini. You can find out the right path with
Module already loaded / Unable to load library
PHP Warning: Module '[some module]' already loaded in Unknown on line 0
PHP Warning: PHP Startup: Unable to load dynamic library '[some module]' ([...]) in Unknown on line 0
During the installation of an extension, pecl adds the extension to the
php.ini file but not removing it
during uninstall. In this case, edit your
php.ini manually and remove deprecated
extension="[some module]" lines.
