The function wordwrap seems to have a bug:

$tmp1="xxxxxxxx! dsfksdjfklsdjf sdflkjxxxx 1111";
$tmp2 = wordwrap($tmp1, 39);

this gives the *wrong* result - this string is 40 chars long!:
--- Cut ---
xxxxxxxx! dsfksdjfklsdjf sdflkjxxxx 1111
--- Cut ---

if you use
$tmp1="xxxxxxxx! dsfksdjfklsdjf sdflkjxxxx 1111x";
$tmp2 = wordwrap($tmp1, 39);

this gives the *correct* result:
--- Cut ---
xxxxxxxx! dsfksdjfklsdjf sdflkjxxxx
1111x
--- Cut ---

Counter used to find split position was compared with the string length. A string of length 40 will have positions 0-39.
The bug has been fixed.
