Help removing a simple space

I need to check for sentences that have a space before the period and
remove the space. I've tried:

$sentence = str_replace(" .", ".", $sentence);

but it does not work. I've tried other ways with no success.

Why doesn't this work and how do I do this?

Thanks!

Maybe they are not spaces (ASCII 32). Could be some other white-space
characters, like TAB (ASCII 9) or FF (ASCII 12). Remember that viewing
text through a browser compresses runs of white-space down to a single
visual space. Look at the HTML source to be sure, ideally using a text
viewer or hex-editor that can highlight different kinds of white-space.

If that's the case look at regular expression functions eg
<http://www.php.net/preg_replace> for a solution.

Ah! That was it. It wasn't a 32, it was a 13 and a 10.

Thanks for your help.
