Install PEAR on OSX Leopard


Unlike previous version of OS X, Leopard doesn’t come with PHP’s PEAR repository installed by default. Luckily, installing is quick and painless. From a command line:

curl > go-pear.php
sudo php -q go-pear.php

Just press enter to select all the default choices except for the installation directory. For that, use /usr/local. (Thanks, Steve.)

Next we need to modify our php.ini file to include the new PEAR files:

sudo cp /etc/php.ini.default /etc/php.ini

Edit /etc/php.ini and change

;include_path = ".:/php/includes"

to read

include_path = ".:/usr/share/pear"

Restart Apache and you’re done!

Install PHPUnit



PHPUnit should be installed using the PEAR Installer. This installer is the backbone of PEAR, which provides a distribution system for PHP packages, and is shipped with every release of PHP since version 4.3.0.

The PEAR channel ( that is used to distribute PHPUnit needs to be registered with the local PEAR environment:

pear channel-discover

This has to be done only once. Now the PEAR Installer can be used to install packages from the PHPUnit channel:

pear install phpunit/PHPUnit

After the installation you can find the PHPUnit source files inside your local PEAR directory; the path is usually /usr/lib/php/PHPUnit.


Although using the PEAR Installer is the only supported way to install PHPUnit, you can install PHPUnit manually. For manual installation, do the following:

  1. Download a release archive from and extract it to a directory that is listed in the include_path of your php.ini configuration file.

  2. Prepare the phpunit script:

    Rename the phpunit.php script to phpunit.

    Replace the @php_bin@ string in it with the path to your PHP command-line interpreter (usually /usr/bin/php).

    Copy it to a directory that is in your path and make it executable (chmod +x phpunit).

  3. Prepare the PHPUnit/Util/Fileloader.php script:

    Replace the @php_bin@ string in it with the path to your PHP command-line interpreter (usually /usr/bin/php).
