Hi Steffen, The reason why 'test' is treated as 0 is that in $x = "String"; $x [ <something> ] is NOT an Array subscript, but an (old) way to extract an character from $x ... Strings are NOT really treated as Arrays, but since it seemed natural to do something like $str [4] (at least for us C-programmers) ... What happens is: 'test' is casted (silently, of course) to an integer; thus yielding 0. If you tried $x ['3 dogs'] you should get the character at index 3. According to http://www.php.net/manual/en/language.types.string.php the correct syntax for accessing a character inside a string is now: $x{idx} (which can't be confused with Array-subscripting anymore). ---- Manual Page -- http://www.php.net/manual/en/language.types.array.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+39594 Delete -- http://master.php.net/manage/user-notes.php?action=delete+39594&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+39594&report=yes Search -- http://master.php.net/manage/user-notes.php
