PHP does indeed perform a numeric comparison when its operands look like numbers, even if their both originally strings. "1" and "1." are identical as far as the comparison operator is concerned, and so are "1.0", 1, and 1.000. If you want a string comparison, without any numeric 'magic', use strcmp() instead (that is the only reason why strcmp() even exists, otherwise the == operator would have been enough).
