1. PHP



PHP: Hypertext Preprocessor is a server side scripting language. For more info please see the Wiki page.


Utilising homebrew it is easy to get the latest version of PHP.

$ brew update
$ brew tap homebrew/dupes
$ brew tap homebrew/versions
$ brew tap homebrew/homebrew-php
$ brew install php56

INI File

PHP stores all its configuration information inside a ini file. The location of this file can be found with

$ php -r "phpinfo();  " | grep -i "loaded configuration file"

Configuration changes can also be supplied in the code and inside an .htaccess file


ini_set( 'post_max_size',       '64M' );
ini_set( 'upload_max_filesize', '64M' );


php_value upload_max_filesize 40M
php_value post_max_size 42M

Image Magick

Source: php-imagick Version: 3.1.0~rc1-1


TODO Upgrade PEAR and PECL

We use ImageMagick images on the server side.

Install PHP5 - PHP-FPM

sudo apt-get install php5-cli
sudo apt-get install php5-suhosin
sudo apt-get install php5-fpm
sudo apt-get install php5-cgi
sudo apt-get install php5-curl
sudo apt-get install php-pear
sudo apt-get install php-apc
sudo apt-get install php5-xdebug

sudo pecl install imagick

sudo service php5-fpm start

sudo nano /etc/php5/fpm/php-fpm.conf

pm                   = dynamic
pm.max_children      = 8
pm.start_servers     = 2
pm.min_spare_servers = 2
pm.max_spare_servers = 3
pm.max_requests      = 500

PHP 5.4

If there are any pre-existing pear install outside of homebrew-php, and you are using a non-standard pear.conf location, installation may fail.

For 10.5 and Apache: Apache needs to run in 32-bit mode. You can either force Apache to start in 32-bit mode or you can thin the Apache executable.

To enable PHP in Apache add the following to httpd.conf and restart Apache: LoadModule php5_module /usr/local/Cellar/php54/5.4.6/libexec/apache2/libphp5.so

The php.ini file can be found in: /usr/local/etc/php/5.4/php.ini


If pear complains about permissions, 'Fix' the default PEAR permissions and config: chmod -R ug+w /usr/local/Cellar/php54/5.4.6/lib/php pear config-set php_ini /usr/local/etc/php/5.4/php.ini


If you are having issues with custom extension compiling, ensure that this php is in your PATH: PATH="$(brew –prefix josegonzalez/php/php54)/bin:$PATH"

Extensions will never be compiled against this homebrew-php PHP. Please install them using –with-homebrew-php to enable compiling against this php.


If you have installed the formula with –with-fpm, to launch php-fpm on startup: * If this is your first install: mkdir -p ~/Library/LaunchAgents cp /usr/local/Cellar/php54/5.4.6/homebrew-php.josegonzalez.php54.plist ~/Library/LaunchAgents/ launchctl load -w ~/Library/LaunchAgents/homebrew-php.josegonzalez.php54.plist

* If this is an upgrade and you already have the homebrew-php.josegonzalez.php54.plist loaded:
    launchctl unload -w ~/Library/LaunchAgents/homebrew-php.josegonzalez.php54.plist
    cp /usr/local/Cellar/php54/5.4.6/homebrew-php.josegonzalez.php54.plist ~/Library/LaunchAgents/
    launchctl load -w ~/Library/LaunchAgents/homebrew-php.josegonzalez.php54.plist

Mountain Lion comes with php-fpm pre-installed, to ensure you are using the brew version you need to make sure /usr/local/sbin is before /usr/sbin in your PATH:


You may also need to edit the plist to use the correct "UserName".

Please note that the plist was called 'org.php-fpm.plist' in old versions of this formula.
