Recently, I’ve started taking some PHP courses.
In the beginning, I’ve used Brackets, which is simple and beginner-friendly but doesn’t have the extra useful features that Visual Studio Code has.
Also, Brackets is used more for web design and front-end development.
Anyway, I installed VS Code, and the first thing I bumped into is this error:
Cannot validate since no PHP executable is set. Use the setting ‘.php.validate.executablePath’ to configure the PHP executable.
If you don’t set the path to the PHP executable, Visual Studio Code will still work fine, but it won’t validate the PHP code, meaning that you won’t get curly red lines whenever you have an error in your code.
After some digging around, I’ve found the solution, and I’ll share it with you ladies and gentlemen because it’s pretty hard to find comprehensive guidance in their documentation or on forums.
VS Code is not for beginners, so they won’t spoon-feed anyone, unfortunately. 🙂
Fix the Validate PHP Error in Visual Studio Code
Note that I’m using Windows 10. If you’re on a Mac, things will be different.
Here’s what you need to do:
You need to find out where your PHP executable (php.exe) is.
That depends on what kind of system you use (XAMPP, WAMP, custom installation, and so on).
I’m using XAMPP, which is installed on my C: drive, therefore the php.exe file is found in C:/xampp/php/php.exe.
Once you’ve found out where your PHP executable is, open Visual Studio Code and go to File > Preferences > Settings.
In the Search Settings bar, type settings.json.
Then, click on the Edit in settings.json link.
Add a comma after the last line of code, whatever it might be, then add this:
Of course, your path to the php.exe file can be different, as I mentioned at step 1, so make sure you replace
C:/xampp/php/php.exe with your correct path.
Don’t add a comma after it if it will be the last line of code!
Save the file by going to File > Save or pressing CTRL+S (for Windows).
I think it’s CMD+S for macOS.
Close Visual Studio Code and open it again for the warning to go away.
Make sure you have PHP added to your environment’s PATH. I think XAMPP adds it automatically but check anyway.
Search for “environment” on Windows.
In the Advanced tab, click on Environment Variables…
Click on the Path row to select it, then click on Edit…
Edit or add a new PHP path (e.g. C:\XAMPP\php).
Don’t add the executable file (.exe) as you did in the .json file. Only add the directory.
Other things to try if it doesn’t work
Some people said that it only worked for them when they added two forward slashes for the path in the settings.json file, like this:
For some people, it worked with backslashes (one or two):
Adding this in addition to the
php.validate.executablePath line might also fix it:
That’s a Wrap
I hope you found this guide useful and you fixed the PHP validation error in Visual Studio Code!
