comparing strings with -0 fail

Question

I cannot manage to do a succesful comparison with the string "-0"

if(strval("-0") == strval("0")) {
    echo '"-0" seems to be same "0"';
}

Result:

"-0" seems to be same "0"

What am I missing here?

And more important, how to work around this?

Answer 1

Use the "===" operator

if(strval("-0") === strval("0")) {
    echo '"-0" seems to be same "0"';
}

but why are you using strval() if the values are strings already?
