How to retrieve number using regex and preg_match in php

I am trying to retrieve the ten digit id number from a textarea.

e.g id no 1234567890

I was trying to use.

preg_match("/('/^[0-9]{10}/')/", $article, $tags);

But it does not work. I 开发者_开发技巧appreciate any help.

Thanks.

Try:

preg_match_all("/\d{10}/", $article, $tags);

preg_match('/[0-9]{10}/', $article, $tags);

Try that. Or if you have multiple IDs, you can use preg_match_all.

preg_match_all('/[0-9]{10}/', $article, $tags);
