Double equals and tripple equals in php

Question

I searched on StackOverflow and Google and I can\'t find the answer to this question:

Should we always use the triple equal in PHP for validation?

For exampl

Answer 1

I would say it is better to always use === and remove one = in cases you can justify.

And yes it's equal, though weird. Better way to write it is if(is_numeric($x) && $x == 1)
