Re: Strange behaviour with the plus sign

[Pedro Tarrinho]

Thanks for replying, but I found the problem.

'' + '' is the same as 0 + 0 which is the same as 'text', which is 0

I mean, the string is being converted to integer because of the + instead of concatenating is converting to numbers (int), which means that 0 (zero) is always equal to 0 (zero).

Got it from here:
