What does “===” mean?

Question

I\'ve noticed someone using the PHP operator === which I can\'t make sense out of. I\'ve tried it with a function, and it corresponds in crazy ways.

Answer 1

See Double and Triple equals operator in PHP that I got for googling on "PHP three equals operator".

At one point it says that:

A double = sign is a comparison and tests whether the variable / expression / constant to the left has the same value as the variable / expression / constant to the right.

A triple = sign is a comparison to see whether two variables / expresions / constants are equal AND have the same type - i.e. both are strings or both are integers.

It also gives an example to explain it.
