here is something I hacked together for Smarty once, modified a bit to suit
your need more (syntax-checked only), maybe it gives you some more to go on:
function ucsentence($string, $lower = false /* dont think this is a good idea*/)
{
if ((boolean)$lower) {
$string = strtolower($string);
}
// find this
$find = array('/e\.g(\. | )/i', '/i\.e(\. | )/i', '/q\.e\.d(\. | )/i', '/ i /i');
// replace with this temporarily
$temp = array('>>::EG::<<.', '>>::IE::<<.', '>>::QED::<<.', '>>::I::<<.');
// replace temp with this at end of processing
$repl = array('e.g. ', 'i.e. ', 'q.e.d. ', ' I ');
// filter out 'e.g's and other text 'atoms' that contain fullstops that do not
// denote the end of a sentence.
$string = preg_replace($find, $temp, $string);
// find sentences
$sentences = preg_split("/(\!(\s)?|\.(\s)?|\?(\s)?)/",$string, -1,PREG_SPLIT_DELIM_CAPTURE);
// build the output string.
foreach($sentences as $k => $sentence) {
if (in_array(trim($sentence), array('.','?','!'))) {
continue;
}
$sentences[ $k ] = ucfirst(trim($sentence));
}
// put the 'e.g.'s back etc
$string = str_replace($temp, $repl, join('', $sentences));
return $string;
}
