php - Make all words lowercase and the first letter of each word uppercase

Question

I have a string with improper capitalization scattered like below:

$str = "tHis iS a StRinG thAt NeEds ProPer CapiTilization";
$newStr = ucfirst($str);
echo $newStr;

How would I be able to capitalize the first letter of each word and lower case the incorrectly capitalized letters? I need the string to be fully title case.

I know I can change to lower and then use ucwords() but is there a shorter way to do this?

ucwords() will capitilize the first letter of each word. You can combine it with strtolower() to first lowercase everything.

For example:

ucwords(strtolower('HELLO WORLD!')); // Hello World!
