从字符串中提取数字，将它们保存到数组中，然后将它们放回字符串中

I've been using stackoverflow to learn a lot about both PHP and JS (incl jquery) so I tend to google all the time but I didn't find an exact reply to this question

I have many strings with words mixed with numbers, like:

"60 reviews from 12 people, 20% of users"

This is an example but it can be much more complex ("word_one 45 word_two word_three 657 word_four 32% word_five USD20")

The use is content localisation:

I want to retrieve the numbers and save them into an array -> done

I want to match these numbers with what I already have in the database, i.e. if I have

en: "2 reviews from 2 people, 2% of users"

es: "2 comentarios de 2 personas, el 2% de los usuarios" -> done too

Now what I want to do is to replace the numbers in the matching string extracted from the database (all of them are "2" because I saved them this way, to avoid the plural-singular problem) with the numbers from the original string in English. Example:

I have this in English:

"60 reviews from 12 people, 20% of users"

I have this in the database:

en: "2 reviews from 2 people, 2% of users"

es: "2 comentarios de 2 personas, el 2% de los usuarios"

I want this in Spanish:

"60 comentarios de 12 personas, el 20% de los usuarios"

Code:

$pattern = '!\d+!';
$repv = preg_replace($pattern, "2", $v);

preg_match_all($pattern, $v, $matches);     
$matchesnb = count($matches, 1);
$pattarray = array_fill("0", "1", array_fill("0", ($matchesnb-1), $pattern));
$reptarget = preg_replace($pattarray, $matches, $dbdata[1]);

Thanks a lot in advance!!

Why don't you save your template sentences in your database ready to be used with the sprintf() function?

$str = array(
    'en' => '%d reviews from %d people, %01.1f%% of users',
    'es' => '%d comentarios de %d personas, el %01.1f%% de los usuarios'
);
$res = sprintf($str['es'],60,12,20);

EDIT: The ordering of words in a sentence is not the same in all the languages. For that reason I think numbering the arguments is a better approach. I added the Turkish option to the array below to show how arg1 and arg2 switch as well as how the percent sign changes place (it's put before, instead of after the number in Turkish, for example).
$str = array(
    'en' => '%1$d reviews from %2$d people, %3$01.1f%% of users',
    'es' => '%1$d comentarios de %2$d personas, el %3$01.1f%% de los usuarios',
    'tr' => '%2$d kullanıcıdan %1$d yorum, tüm kullanıcıların %%%3$01.1f\'si'
);
$res = sprintf($str['es'],60,12,20);
