Updating PHP 5.5 to PHP 5.6 in Homebrew

update.sh

# Unlink your existing php installation
brew unlink php55

# Install the version you need
brew install php56

# Check for errors
# If you get: "Error: Directory not empty - /usr/local/opt/php56"
# Simply remove the directory with
sudo rm -rf /usr/local/opt/php56
# and create the symlinks
brew link php56

# Now your php version should be up to date via the command line:
php -v

# Finish off the installation by configuring Apache to use the correct version
# Take note of the .so library for the new PHP version
brew info php56

# And copy the following
# To enable PHP in Apache add the following to httpd.conf and restart Apache:
LoadModule php5_module    /usr/local/opt/php56/libexec/apache2/libphp5.so

# And replace the existing line in your Apache configuration file
sudo vi /etc/apache2/httpd.conf

# To finish up, you will need to transfer any configuration changes to your new ini file:
# To get the ini file, simply search for it:
php -i | grep php\.ini

# Which should echo:
# Configuration File (php.ini) Path => /usr/local/etc/php/5.6
# Loaded Configuration File => /usr/local/etc/php/5.6/php.ini
# So just edit that ini file
sudo vi /usr/local/etc/php/5.6/php.ini

# Make your changes to any settings (such as timezone and short_open_tags)

# Restart Apache
sudo apachectl restart

# And restart PHP
brew services start homebrew/php/php56
