Nope. The question was the position of the words, not how many times
they appear.

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.

RE: [PHP] Divide into words
True, but it answers the original question. :) You can easily throw in a if($word == ' ') then don't save it, but still increment $pos. You could use a regular expression to check/remove punctuation, too. ---John W. Holmes... PHP Architect - A monthly magazine for PHP Professionals.

RE: [PHP] Divide into words
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);

Re: [PHP] Divide into words
You could use strpos--there are easier ways if you don't need the offsets. Example: This is from memory, but it looks like it should work even for weird strings like the one above.
