Inconsistent String Definition (string position starts at zero)?

Hi all, I had previously discovered (after searches within strings weren't working properly) that string characters in PHP3 begin at position 0 (zero). This in itself seems obtuse. But there is a more serious problem. For example: $t="text string" Therefore: strpos($t, "text") evaluates as 0. Because of this definition you can't use this conditional test below to test whether a string contains a subset of characters: if (strpos($t,"text")==true) ... ...because it can evaluate as false even when the string contains the characters you are looking for! (false=0 per the PHP manual). This also seems to seems to contradict the PHP3 manual for strpos: If needle is not found, returns false. (Well it's not a direct contradiction, but it seems to be highly unhelpful because if needle is found it can also return false). Is there something I am doing wrong (or have configured wrong) or does PHP just have this inconsistency? Many thanks, Adam Warner
