PHP script to strip all CAPS and then only Capitalize first letter of each word

I'm looking for the PHP script to strip all CAPS and then only Capitalize first letter of each word...

ie. "THIS IS A TEST" becomes "This Is A Test"

Can anyone help?

 

$words = ucwords(strtolower($words));

 

Thank you for your prompt response.

 

What would the modification be if some of the values are in the format "WESTON-SUPER-MARE" or "BARROW-IN-FURNESS" using "-" instead of space (and you want to retain those "-"s) but want to apply the capitalization rule?

 

Ok just found a function for this elsewhere, so posting it here incase anyone else needs it:

<?
function Capitalize($name) {
$name = strtolower($name);
$name = join("'", array_map('ucwords', explode("'", $name)));
$name = join("-", array_map('ucwords', explode("-", $name)));
$name = join("Mac", array_map('ucwords', explode("Mac", $name)));
$name = join("Mc", array_map('ucwords', explode("Mc", $name)));
return $name;
}
echo Capitalize('BURY-ON-THAMES') . '<br>';
echo Capitalize('ISLE OF WIGHT') . '<br>';
echo Capitalize('MCDONALD') . '<br>';
?>

 

You don't need the function. The above should work fine, even if it contains dashes.

Peace,
