After a certain update of the Brackets software you might get the following error:
PHP runtime not found. Install the PHP7 runtime and update “executablePath” in PHP Preferences appropriately. This enables PHP-related tooling such as Code Hints, Parameter Hints, Jump To Definition and more.
Here is the solution that did the trick for me.
1. Download PHP7
Go to official PHP website to download the PHP7.x version that you need and extract it to a location on your computer. In my case I did it in the root of C:\ directory.
2. Make changes in System Properties
2.1. You can either type “Advanced system settings” in windows search box (Windows key + S), or right click on My Computer > Properties > Advanced system settings
2.2. Then chose “Environment Variables…”
2.3. Then in the System variables part of the box click on Path/Edit…
2.4. In the next box click on New
2.5. Paste the path to the PHP folder on your computer and click OK.
