PhpStorm glue together signs

I can't find how to make

=> == === != !== ect.

looks like one sign in phpstorm

Could some one help me to find this settings?

It's called "ligatures" and can be enabled in:

1. Settings/Preferences
2. Editor | Color Schema | Color Schema Font (or maybe just Editor | Font -- I'm not 100% sure what this new settings page does exactly)
3. Enable font ligatures option.

Obviously, you need to have fonts that support such symbols installed on your computer/OS.

Looks like only Fira Code is bundled with the IDE and other supported fonts you may need to install manually -- see below.

Support for ligatures in editor

PhpStorm now supports fonts with programming ligatures, like Fira Code, Monoid or Hasklig.
