A non-numeric value encountered in file F:\xampp\htdocs\Escubydu\app\Http\Controllers\API\HotelController.php on line 364 code example

Example: non-numeric value encountered php

Not exactly the issue you had but the same error for people searching.

This happened to me when I spent too much time on JavaScript.

Coming back to PHP I concatenated two strings with "+" instead of "." and got that error.
