Question:
How to Increment and decrement value of a given column in Laravel 7 ?
Solution:
if you want to increment or decrement some DB column in some table, just use increment() or decrement() functions. Oh, and you can increment or decrement not only by 1, but also by some number, like 5.
Examples:
Post::find(1)->increment('votes');
Post::find(1)->increment('votes', 5);
Post::find(1)->decrement('votes');
Post::find(1)->decrement('votes', 5);
