A simple function that just helps if you're processing some user generated input and the user seems to have problems using uppercase letters... like for their name, etc....

#
#	Quick function to first switch all words to lowercase,
#	then capitalise the first letter of each word.
#
function flattenAndFatten($word){
	$word = strtolower($word); // Lowercase
	$word = ucfirst($word); // Capitalised
	return $word;
}

It is used like this:

$name = 'jon Moore';
$betterName = flattenAndFatten($name);
echo $betterName;

This will output Jon Moore
