How to Split a Paragraph into Sentences

I've been trying to use:

$string="The Dr. is here!!! I am glad I'm in the U.S.A. for the Dr. quality is great!!!!!!";
preg_match_all('~.*?[?.!]~s',$string,$sentences);
print_r($sentences);

But it doesn't work on Dr., U.S.A., etc.

Does anyone have any better suggestions?

there is not any simple solution for that. you need do some natural language processing(NLP) in your application and recognize each sentence. there is something call OpenNLP, it's a JAVA-based NLP parser tool. Or Stanford NLP parser in Ruby. you can find something like that for php.

here I found a set of classes for natural language processing in PHP.

This is almost impossible since your example clearly indicates that punctuation characters that can be used in e.g. Dr., U.S.A etc, make it impossible to know where a sentence starts/ends.

You have to search the following characters to decide if a new sentence follows (starts after) the punctuation chars you are mentioning.

hmmm maybe try something like $sentences = preg_split('/.*?[?.!]+\s+/', $string);
