Good day!
Please tell me Cloud IDE, comparable in functionality to PHP Storm.
Basically, I work with the following technology stack in projects:
1. Composer
2. PSR-0 / PSR-4
3. Magento (for PHPStorm there is Magicento)
Based on this, the main requirements are:
1. Code completion with namespace processing
2. Navigation code (very beloved Ctrl + Click from the storm)
3. Highlighting errors (preferably also unused variables, etc.)
