The function strcmp() simply evaluates two strings and reports

back -1, 0, or 1 depending upon their alphabetical relationship.

It might do that, but don't bet your horse on it. <http://se.php.net/manual/en/function.strcmp.php>

/Nisse It works that way for me.

Are you absolutely certain about that? echo strcmp('These are nearly equal', 'These are almost equal'), "\n"; echo strcmp('different', 'unequal'), "\n"; echo strcmp('b', 'a'), "<br />\n"; Result: 13 -17 1 The description of the function merely says that the result is <0, 0 or >0 -- it makes no promises about the actual value when it is non-zero.

Mike: That's interesting. Try the same comparisons here: http://www.webbytedd.com/lcc/citw229/string-compare.php For me they are 1, -1, and 1. Someone with more smarts than me* will have to figure this one out. Cheers, tedd PS: * I can hear the peanut gallery saying "That won't be hard." :-) -- ------- http://sperling.com/
