    $firstSetOfNumbers = preg_match("/d+(s|$)/", $string);

    that should be correct.

    $my_string  = "(VAT code) Địa chỉ (Address) 034372 350-352 Võ Văn Kiệt, Phường Cô Giang";
$pattern = "/d+/";
preg_match($pattern, $my_string, $matches);
echo $matches[0]; //Outputs 034372

    You can use preg_match to do this. If you pass a third argument ($matches) to preg_match it will create an array filled with the results of search and $matches[0] will contain the first instance of text that matched the full pattern.

    If there is a chance no numbers will be in the string, you can identify those cases with an if statement like this:

    if (preg_match($pattern, $my_string, $matches)) {
    echo $matches[0];
}
else {
    echo "No match found";
}
