Your version has more options in that you can supply a length though.

uc_sentences is a nice idea. Here’s a simpler way of doing it:

function uc_sentences($text) {

$sentences = preg_split(“/([\.\?\!]\s*)/”, $text, null, PREG_SPLIT_DELIM_CAPTURE);

$output = “”;
foreach($sentences as $sentence) {
$output .= ucfirst($sentence);
}

return $output;
}

echo “[".uc_sentences(" hi.i like to eat potato chips. go eat potato chips! where are the chips? here they are")."]“;

Hope the code comes out ok.
