Intention actions
As you work in the editor, PhpStorm analyzes your code, searches for ways to optimize it, and detects potential and actual problems.
As soon as the IDE finds a way to alter your code, it displays a yellow bulb icon 
in the editor next to the current line. By clicking this icon, you can view intention actions available in the current context. Intention actions cover a wide range of situations from warnings to optimization suggestions. You can view the full list of intentions and customize them in the Settings/Preferences dialog Ctrl+Alt+S.
A red bulb with an exclamation mark 
indicates that PhpStorm has detected a problem, and prompts you to select an associated fix — a quick-fix. Quick-fixes and intention actions together are called context actions.
