Several of these solutions are good ideas, but they don't preserve the
whitespace as he desired. Preg_split with the capturing of the (\s+)
delimiter does the trick.

Uuhmm, I'm sorry. I haven't read it throught to the end. The solution
ist a
bit different:
use preg_replace to replace multiple spaces with single spaces:
$sometext2split = preg_replace("|", " ",$sometext2split); #make shure
that
the separator isn't in the text anywhere around
$sometext2split = preg_replace("/\s+/", "| |",$sometext2split);
and then explode the string (i don't know wether explode or preg_split
is
faster, I tend to explode for simple split operations):
$myarray = explode("|",$sometext2split);
this should work. But probably it was a better solution to insert the
spaces
with a loop between the words than to run the risk, that the separator
is
somewhere in the text...
