Nice tool which clear my logic. I have also contributed in this topic, you would like it.

@Matchendran: functions are not allowed within the textareas and input fields

I tried to use some string functions in the $start and $length field, but its returning the value 0 instead of returning the correct value.Won't those fields take string functions as their input??

Thanks for this online tool, like it :)

@djay: congrats, you found that out without reading the info on php.net or at the top of this page :-P

If $start parameter is negative counting is done from right, and counting is done from 1 not from zero.
