If the token character is the first of the string you want to tokenize,
now strtok ignores it, before it would return an empty string. For
instance strtok("/something","/") would return "" but since strtok was
broken it returns "something". This makes strtok completely useless to
break an arbitrary string by tokens because it will discard the first
token if it is an empty string.
The strtok function behaved like that since it was introduced in PHP 3.
If you figure that this change will break your PHP code, you may want to
try the function in the page below. It also contains a fixed version of
dirname that was also broke between PHP 4 and 4.1.0.
