Thanks for all the help from everyone.. and yes, Vsloathe, the last one did retain the punctuation mark.
Makes it more better....
Wonder if the more complex formula will cause a noticable slowdown when using large files..
I may try it on a large text file and measure the processs time and if a noticable difference stick adding a period after each one as 99% will be period anyway... So what is a few missing question marks among us scrapers. he he..
Thanks again for all the help.

yes it will.

speed is a factor of file size and regex complexity.
realize though that regex complexity might not always be what you think.

but in the same vein, its also probably the most efficient choice you have usually.

[vsloathe]

Any zero-width tuple representations in regex are pretty hefty. Also negative and positive lookarounds and lookbehinds make it CRAWL if you're doing enough of them.

At that point, it would be faster to convert all sentence breaking instances (". ", "! " "?") into a single special character and then explode on it, thus:

$newBuff = str_replace(array('. ', '? ', '! '), '###', $inputBuff);
$array = explode('###', $newBuff);

But the regex I gave him should be fast enough. It doesn't use any advanced regex syntax at all, it's extremely basic.

You geeks love to discuss processing speed.   

I am pretty sure he was talking only of the additional code to capture the punctuation.

It's not going to be noticable unless the file is FRIGGIN HUGE.

imo
