I'll take that bet and say using preg_*_callback will be slower. :) I'll try and time each of them tonite and post what I find.

Yes, but my example was geared towards trying to work through a more
generic scenario. I'll bet if you try using perl regex with callback
it'll be even faster.

Hi!
I have dome almost the same
$input = 'Today is a very beautiful day and the sun is shining';
$output = array();
$words = explode(' ',$input);
$cur_pos = 0;
foreach($words as $word) {
if(!empty($output[$word])){
$output[$word] .= ','.$cur_pos;
} else {
$output[$word] = $cur_pos;
}
$cur_pos += strlen($word) + 1;
}
unset ($word);
but i thought if there is some better way. I also tried
Marco's example and adjust it a little bit to get the same
results. And here is some benchmark i have.
with this example i get 0.0024310350418091
and with Marco's i get 0.0034389495849609s
So using two array is faster anyway. Probably of explode
speed.
