add dots in digits

[mraza]

Hi,

 

I have a text where i need to replace space between digits with dots.

example:

And today date 2011 03 28 and also some other text
and this could be second line of7 2 6 0 and continue like this...
some other number like 8 0 6 9 and some other as well.
but it will not add dot to this single digit 01 or even to this word 2000 as those are single 
// there could be more this type of digits 

 

Now i need to replace that date to 2011.03.28 and of7.2.6.0  and 8.0.6.9, i have various this type of digits i need to replace only space with dots between digits using regex, any help please to show me a regex pattern plz.

Thanks

$change = preg_replace("/(\d+)(\s)|(\s)(\d+)/", "$1.$3", $change);

function my_to_dot($a){
    return preg_replace('/\s+/', '.', $a[0]);
}
echo preg_replace_callback('/(\d+\s+){2,}/', 'my_to_dot', $test);
?>

Thanks a lot for the code, i have actually a little problem still in that. if i use that code or mine above it will add dots to numbers i wants but i do not wants it to add dot at the last number,

 

like its converting this 2011 03 02 to 2011.03.02.  <<< it is adding one dot at the end, is it possible to convert that to 2011.03.02 so no dot at the end.

 

Thanks again

You can use a plain regex without any fancy callback shenanigans. Here's one that's as simple as I can make it.

 

preg_replace('/(\G|\d)\s(\d)/', '$1.$2', $subject)
