regex for preg_match_all to get only 10 chars in string

Question

Using my code bellow, How can I get results array only for users who have 10 chars in address with preg_match_all and regular expressions?

this is my code

$data = 'Maria address is QwMP_jkRkM and lives in Peru, Joseph address is QMPjkRk2ZM and lives in Peru, Miguel address is Q.wMP_jkRljo_hkM and lives in New York, George address is hdiJoW58_7 and lives in Austria';

preg_match_all('#(.*?) address is (.*?) and lives in (.*?)#', $data, $output);

Actually returns all matches, I need to remove the results that contain more than 10 characters in their address.

Note: I should not use foreach

`{10}` - for exact 10 chars (instead of the *). * and ? together don't really make sense. * matches 0-unlimited, ? matches none-one — Jeff, Sep 11 '18 at 01:16

The constraints seem artificial, but this should produce the correct output (if awkwardly) and it does use (.*?):

$data = 'Maria address is QwMP_jkRkM and lives in Peru, Joseph address is QMPjkRk2ZM and lives in Peru, Miguel address is Q.wMP_jkRljo_hkM and lives in New York, George address is hdiJoW58_7 and lives in Austria';

preg_match_all('#([^ ]*?) address is (.{1,10}) and lives in (.*?)(?:$|,)#', $data, $output);

print_r($output);

Result:

Array
(
    [0] => Array
        (
            [0] => Maria address is QwMP_jkRkM and lives in Peru,
            [1] => Joseph address is QMPjkRk2ZM and lives in Peru,
            [2] => George address is hdiJoW58_7 and lives in Austria
        )

    [1] => Array
        (
            [0] => Maria
            [1] => Joseph
            [2] => George
        )

    [2] => Array
        (
            [0] => QwMP_jkRkM
            [1] => QMPjkRk2ZM
            [2] => hdiJoW58_7
        )

    [3] => Array
        (
            [0] => Peru
            [1] => Peru
            [2] => Austria
        )

)

This is the correct regex. ty – jose sanchez Sep 11 '18 at 03:34 — jose sanchez, Sep 11 '18 at 03:34
