problem in what you wanna do, I can just spot an error in the root of the

there is nothing messy, the logic is well defined and for a loose type language
it's absolutely normal behavior.

$b , $c, and $d are the same indeed ... they represent the floating point
2260.0 in I think every language ... it's like saying that 1.0 is not 1.
... both floating point numb

I am well aware of the === operator, but I had an uneasy feeling that there was
still a
trap. However when I tried it it worked, so I was going to thank you for your
suggestion,
though I find the concept of having separate 'sort of equal' and 'truly equal'

if we compare via "==" there is an implicit cast to the most primitive form.
These are all true, and all have a reason, and make sense:
// (int)'abc' is 0
var_dump('abc' == 0);
// 'abc' is not an empty string
var_dump('abc' == true);
// 2 is not 0, which would be casted into false, so it's tru
