# Upgrade php in brew & keep phpcs

- still valid for v5.6.16

Every time you upgrade php, you loose `phpcs` command. So, you need install it again.
**Prerequirement:** You need to install php with pear enabled: `brew install php56 --with-pear`

## Steps

````bash
$ brew upgrade php56

# to ensure all lib can be writable by pear
$ chmod -R ug+w /usr/local/Cellar/php56/<VERSION>/lib/php/

$ pear config-set php_ini /usr/local/etc/php/5.6/php.ini system

# write dovn all of your custon installed package
$ pear list
# Standard packages are:
#   Archive_Tar
#   Console_Getopt
#   PEAR
#   Structures_Graph
#   XML_Util

$ pear upgrade-all

$ pear install PHP_CodeSniffer

# now you can clean up old formulae
$ brew cleanup
