PHP CodeSniffer into PHP Storm

Install PHPCS in mac

sudo cp /private/etc/php.ini.default /private/etc/php.ini;
sudo php /usr/lib/php/install-pear-nozlib.phar;
pear config-set php_ini /private/etc/php.ini;
pecl config-set php_ini /private/etc/php.ini;
sudo pear upgrade-all;
sudo pear install PHP_CodeSniffer;

Do not forget to add /usr/lib/php/pear/ to your include_path

Configure PHPCS into PHP Storm

Settings > Languages & Frameworks > PHP > CodeSniffer

put the path for phpcs (locate it with which phpcs in your terminal) and validate it, apply and we're done.

Settings > Editor > Inspections > PHP > PHP Code Sniffer validation

Enable it and search in the screen for Coding Standard and pick PSR2

I was facing another error when running phpcs in terminal on zsh:
mac os x phpcs command not found

This can be resolved by getting the bin path for phpcs, by running below command in terminal:
pear config-get bin_dir

This shows something like
/usr/local/opt/[email protected]/bin

Then add an environment variable in ~/.zshrc. Simply add the following line in ~/.zshrc:
export PATH=/usr/local/opt/[email protected]/bin:$PATH
