PHP cast float to string is different from cast to int

Question

Something you would not expect but need to be aware of when you\'re dealing with floating point numbers in php

Answer 1

You're casting $i (3287) to a string and then to an int, so the result stays 3287. If you cast $i to an int you'll get 3286, and then if you cast it to a string you'll have what you want.

Try echo (string) (int) $i
