If you are looking for a way to trim a sentence and append, say like ... at the end. I created this
little snipplet that seems to work fine for what I need.
function trim_sentence($string, $num)
{
$done = 0;
$letters = 0;
$sentence = '';
$words = explode(" ", trim($string));
$totalwords = count($words);
for($i = 0; $i < $totalwords; $i++) {
$word_array = preg_split('//', $words[$i], -1, PREG_SPLIT_NO_EMPTY);
$letters = $letters + count($word_array);
if (($letters > $num) && ($done == 0)) {
$sentence = trim($sentence) . "...";
$done = 1;
}
if ($done == 0) {
$sentence .= $words[$i] . " ";
}
}
return ($sentence);
}
It will append to the smallest number. For instance:
$forum = "Wolrds Biggest Ralley";
$forum = trim_sentence($forum, '15');
echo $forum;
Result: Wolrds Biggest...
