John,
I'm not sure this will work if there is more than one space between
words.
Also, my previous example won't work if there are duplicate words
(although it's easy to make an array out of each word and solve the
problem), nor if the words are delimited by any character other than
spaces, in which case regex are probably our best bet.
Cheers,
Marco

Well you could've at least shown us what you had so far instead of
letting us solve the problem for you:
$string = "Today is a very beautiful day and the sun is shining";
$words = explode(" ",$string);
$pos = 0;
foreach($words as $word)
{
if(isset($w[$word]))
{ $w[$word] .= ",$pos"; }
else
{ $w[$word] = $pos; }
$pos += strlen($word) + 1;
}
print_r($w);
