在php中用正则表达式获取数字

Question

I am trying to extract all the numbers from a page. The page looks like this:

....lots of html code ....
<script>
..some code...
["listidname",[],{"list":["123456","96326478664","12345678901234"]},12]
...more code....
</script>
...even more code...

The amount of numbers in the list can vary, also the 12 at the end is just a random number, so this can vary as well.

what I am trying to do is extract the 123456, 96326478664 and 12345678901234. However I am not really strong with php let alone regexes..

preg_match_all("/(\d+)/", $input, $output);

gives me the numbers, but also all the other numbers on the page...

Can anyone help me with this? Thank you.

You must first extract the line and after find the numbers:

if (preg_match('~\["listidname",\[],\{"list":(?:[[,]"\d++")++]},\d++]~', $html, $match)) {
    preg_match_all('~"\K\d++~', $match[0] ,$result);
    print_r($result);
}
