PHP String Chopping Excerpt

$string = 'Lor em ipsum dolor sit #hastag amet, consectetur adipiscing elit. Sed metus augue, mollis non ornare eget, consectetur non eros. In hac habitasse platea dictumst. Duis egestas ultricies iaculis';
$before = 10;
$after = 10;
$find = '#hastag';

$pos = strpos($string, $find);

$start = $pos - $before; // work out where to start
$length = $start + $after + strlen($find) - 2; // work out where to end

$start = max($start, 0); // make sure we don't start before the beginning of the string
$length = min($length, strlen($string)); // make sure we don't end after the end of the string

$new = substr($string, $start, $length);

echo $new;

?>
