That's because they are equal! PHP interprets the string "0X0" as zero
in Hexidecimal and that is equal to 0.

What are you trying to accomplish?

Yes, since that is exactly what to expect according to the == operators
specs

Probably string comparison. Use strcmp().

Hi ;)

Thank you everybody, I used strcmp and everything is ok now.

What are you trying to accomplish?

Well, my strings full of "0" or "X" are results of analyses.

Try === or strcmp() instead.

And do you understand why you got the result you got? The "==" operator
will try to convert its operands to integers if it can. "0X0" is a hex
constant that happens to evaluate to the integer 0. "000" is a decimal
(arguably octal) constant that happens to evaluate to the integer 0.
Equal.
