Hi, I'm trying to trace a bug in osCommerce 3, but it uses "===" in many of it's if statements. What is the behaviour of "==="? I see it first time and php manual doesn't mention it.
Is it's functionality same as "=="?

It's the same as == but with a little bit more, it actually compares the datatype as well as the datavalue
if (0 == 0.0) //compares an integer to a float, will return true
if (0 === 0.0) //compares an integer to a float, will return false
And the
PHP manual mentions it plenty if you look
