Extract ids (values) with regex?

I have a text

[wow id="44"] bla bla bla [wow id="99"] bla bla bla [wow id="100"] bla

How do I get the values 44, 99, and 100 in a smart way? Is regex "the way to go" ?

php:

 $re = "/\\[[\\w\\s]*id=\"(\\d+)/m";
    $str = " down vote favorite\n    \n\nI have a text\nid=\"44\"\n[wow id=\"44\"] bla bla bla [wow id=\"99\"] bla bla bla [wow id=\"100\"] bla";

    preg_match_all($re, $str, $matches);

try with preg_match_all()

$str = '[wow id="44"] bla bla bla [wow id="99"] bla bla bla [wow id="100"] bla';
preg_match_all('/[1-9][0-9]*/', $str, $m);
print_r($m);//Array ( [0] => Array ( [0] => 44 [1] => 99 [2] => 100 ) )

This may help you

preg_match_all("/\b(\d{6,20})\b/", $input_lines, $output_array);

Here is the result.

Use \K to discard the previously matched characters from printing in the final output.

\[wow id="\K[^"]*(?="])

Code:

preg_match_all('~\[wow id="\K[^"]*(?="])~', $str, $match);

OR

Use capturing groups.

\[wow id="([^"]*)"]
