hi,

i discovered a small bug in wordwrap. if you call this function with 4 parameters and a width of 0 your php-script will crash/timeout.

<pre>
<?php
 $string = "the quick brown fox ...";
 echo wordwrap($string, 0, "\n", 1),"\n";
?>
</pre>

here is an inconsistency with the 2-parameter version, which returns all words separated by \n in this case

regards marc

forcing a cut with a zero width doesn't make any sense. but segfault fixed in cvs and this case now issues a warning. (but also found and fixed a related crash if a multi-character break was used with a zero width.)
