Based on szeryf at negativeIQ dot pl's post on 02-Apr-2003 05:41, regarding truncating strings
to the nearest whitespace.. I've come up with a slightly modified version.
The original version would stop at a newline and hence not output the specified number of
characters.
function truncate ($var, $len = 120) {
if (empty ($var)) { return ""; }
if (strlen ($var) < $len) { return $var; }
if (preg_match ("/(.{1,$len})\s./ms", $var, $match)) { return $match [1] .
"..."; }
else { return substr ($var, 0, $len) . "..."; }
}
The only difference is with the regular expression, from:
"/(.{1,$len})\s/"
to:
"/(.{1,$len})\s./ms"
Hopefully this is helpful for someone other than myself. :-)
