How can I put sentences into an array?

Hello everyone, I'm really new to php, here is what I want to do.

Search through a body of text, untill it reaches "." "!" or "?" followed by single or double quotes, or a space. then put all text its gone through so far into the first array element. Then start over from that position.

I was trying to do it like this: $url = explode("[.|/?|!] ", $_REQUEST["text"]);
but it wasn't working, I can only get it to work for a single punctuation, and then the data in the arrays doesn't have punctuation, which is a bad thing. Can anyone help please?

edit: the final purpose of the script is to display the shortest 5 and longest 5 sentences in the text, if that matters at all

 

It looks like you may need regex

$regex = '/(.+[\.!\?])\s/s';
$sentances = preg_split($regex, $text);
var_dump($sentances);

Nice one streety.
