php pattern for text (if there is any dot found set a single space for next word!)

Here is my code:

if(isset($_REQUEST['Submit']))
{
//capture name from textfield
$name = $_POST['name'];

//make pattern for name
function checkName($uname)
{
$pattname = "/^[a-z\.\s]+$/";
return preg_match($pattname,$uname);
}

if(!checkName($nama))
{
//display error for invalid name
echo "$nama invalid name!";
}
else
{
//display formated name if name is valid
echo "Your name: ".ucwords(strtolower(wordwrap($nama)))." (after formated!)";
}
}

My problem is i can't make a pattern for short name like "M.Micheal" where if there is any dot(.) found set a single space for next word after dot (M. <space>Micheal OR M. Micheal). Is that possible to using ereg_replace() function?

I have been completed, here is the solution...

//just add str_replace() function like below
echo "Your name: ".ucwords(strtolower(wordwrap(str_replace(".", ". ",$name))))." (after formated!)";
