How to replace all Uppercase letters with spacing in PHP?

What about something like this :


$string = "MaryGoesToSchool";

$spaced = preg_replace('/([A-Z])/', ' $1', $string);
var_dump($spaced);

This :

•     Matches the uppercase letters
•     And replace each one of them by a space, and what was matched

Which gives this output :


string ' Mary Goes To School' (length=20)


And you can then use :


$trimmed = trim($spaced);
var_dump($trimmed);

To remove the space at the beginning, which gets you :


string 'Mary Goes To School' (length=19)
