PHP: Extract using regex, preg_match() function

I want to extract the numbers 3 and 2 using preg_match()

[{"id":"3","value":"2"}]

These numbers won't be the same every time, it'll be generated depending on witch page the user is viewing.

The code you are trying to extract is JSON. If you want to use preg_match, you can use Ωmega-'s solution (which I corrected a small bit '/'-slashes we're not included):

$str = '[{"id":"3","value":"2"}]';
preg_match('/(\d+)\D+(\d+)/', $str, $json_object);
$id = $json_object[1];
$value = $json_object[2];
echo $id;
echo $value;

If parsing JSON is what you're after: 

$string = '{"id":"3","value":"2"}';
$json_dec = json_decode($string, true);
$id = $json_dec['id'];
$value = $json_dec['value'];
echo $id;
echo $value;

Hope this helps.

The data appears to be JSON. As such, do not use Regular Expressions, use json_decode().

print_r(json_decode($yourdata, true));
