Why does (0 == 'Hello') return true in PHP?

Question

Hey, if you have got the following code and want to check if $key matches Hello I\'ve found out, that the comparison always returns true

Answer 1

pretty much any non-zero value gets converted to true in php behind the scenes.

so 1, 2,3,4, 'Hello', 'world', etc would all be equal to true, whereas 0 is equal to false

the only reason !== works is cause it is comparing data types are the same too
