[PHP] Spread camel case

My work has me doing Wordpress plugins from time to time. The following snippets comes from one of those projects. It's text a camel-case string and inserts spaces in front of capitals and numbers, turning the item into some more human-readable.
function spreadCamel($txt) 
  $temp = substr($txt,0,1);
  for ($i = 1; $i < strlen($txt); $i++) {
   $c = substr($txt, $i, 1);
   if (ctype_upper($c) || ctype_digit($c)) {
    $temp = $temp . " ";
   $temp = $temp . $c;
  return $temp;
An example invocation:
echo spreadCamel("MyDogHasFleasAbout1Million");
the result of that being
My Dog Has Fleas About 1 Million
I hope that helps someone. There may be a better/faster/more efficient way of doing it. If there is, please post in the comments.

Anything would always involve walking from one end of the string to the other and looking at the codepoint. The only saving I suspect would be convincing PHP to do that natively (like a regexp search and replace).

Thank you for sharing
