Convert a camelCase or underscore_separated string to Title Case. Useful for converting database column names to readable text.

valueToTitle.php

<?

// Convert a camel-case or underscore_separated string to Title Case
function valueToTitle($string) {
	$string = preg_replace('/(?!^)([[:upper:]][[:lower:]]+)/', ' $0', $string);
	$string = preg_replace('/(?!^)([[:lower:]])([[:upper:]])/', '$1 $2', $string);
	$string = str_replace('_', ' ', $string);
	$string = ucwords($string);
	return $string;
}

?>

If all you need is camelCase to Title Case conversion then there's a single line function for that here: https://gist.github.com/andrewspear/6680029
