The Ultimate Git Alias Setup

If you use git on the command-line, you'll eventually find yourself wanting aliases for your most commonly-used commands. It's incredibly useful to be able to explore your repos with only a few keystrokes that eventually get hardcoded into muscle memory.

Some people don't add aliases because they don't want to have to adjust to not having them on a remote server. Personally, I find that having aliases doesn't mean I that forget the underlying commands, and aliases provide such a massive improvement to my workflow that it would be crazy not to have them.

The simplest way to add an alias for a specific git command is to use a standard bash alias.

Debug your PHP in Docker with Intellij/PHPStorm and Xdebug

For your local dev, create a Dockerfile that is based on your production image and simply install xdebug into it. Exemple:

FROM php:5

RUN yes | pecl install xdebug \
&amp;&amp; echo "zend_extension=$(find /usr/local/lib/php/extensions/ -name xdebug.so)" &gt; /usr/local/etc/php/conf.d/xdebug.ini \

	* @param $callback Callback The filter callback, that will get the key as first argument.
	*
	* @return array The remaining key => value combinations from $array.
