PhpStorm is the only PHP IDE that deserves to be called IDE, IMO. Everything else is inferior at best and only gets in your way at worst. PhpStorm is the only PHP IDE that deserves to be called IDE, IMO. Everything else is inferior at best and only gets in your way at worst. I am not paid to say that. I simply cannot imagine working productively with something else. Php Inspections (EA Extended) Php Inspections (EA Ultimate) Dependency Management https://github.com/composer/getcomposer.org/issues/36 https://youtu.be/Ci_I0ATr748 Composer "[e]nables you to declare the libraries you depend on" and "[]inds out which versions of which packages can and need to be installed, and installs them (meaning it downloads them into your project)". $ curl -s https://getcomposer.org/installer | php

$ composer self-update Do not "cURL and pipe to bash"!

Users are encouraged by documentation to copy/paste commands such as

$ curl -s https://getcomposer.org/installer | php into their shell.

This prevents any verication of authenticity and integrity of the downloaded executable before running it.

Users doing this are literally asking for their system to be compromised! https://thephp.cc/news/2019/02/blast-from-the-past Life is too short to talk about dead technology. $ mkdir project
