Answer 1

You can use strpos()

$pieceLength = strpos($string," ",12);

http://php.net/manual/en/function.strpos.php

Answer 2

something like this:

while ($string[$pieceLength]!=' ' || $string[$pieceLength]!='\n')
   $pieceLength++;

substr($string, $pageNo, $pieceLength);

Also consider php builtin wordwrap

Answer 3

Look at strpos() ; offset would be $pieceLength , but position returned is still from beginning of the haystack.
