Split a string - or can you?

[ddrake1984]

I need to split a string, but in a very unusual way.

$string1 = "HelloWorld"
$string2 = "AlphaBravo"
$string3 = "BreakMeUp"

I need the following split at each upppercase letter for this output

Hello World
Alpha Bravo
Break Me Up

I received the assistance I needed from phpfreaks.com

$string = 'ThisText';

$newstring = '';
foreach( str_split( $string ) AS $letter ) {
$newstring .= ( ctype_upper( $letter ) ? ' ' : '' ) . $letter;
}
$string = trim( $newstring );
