    This gets both strings as requested -

    $ary = explode(' ', $str300);
    $a = implode(' ', array_slice($ary, 0, 70);
    $b = implode(' ', array_slice($ary, 71);

    Assuming there was only one space between words, assuming no tabs
    separating words, etc., etc.

    It's kind of expensive, though. If performance is an issue, you might want use strpos to get to the breaking space (through a loop or some such construct), and then use substrings from the strpos return.

    If someone else need it I used this:
    $b = substr($a, 0, 350);
    $c = substr($a, 350);
