PHP Regex无法正常运行

I have a variable that can receive these two values:

'01838723001603 TELO 155' ou '01838723009850 0608'.

I want to get the second value after the number of 14 characters. For that, I'm trying the following regular expression, but it is not working:

/[0-9]{14} (.*?)/i

preg_match_all('/[0-9]{14} (.*?)/i', $data, $result);
var_dump($result);

Result -> [0 => '01838723026436', 1 => '01838723026436'].

She's just taking the first value (01838723001603).
I want her to return values: 'TELO 155' / '0608'

(this has to be done using regular expression, because these data are being captured from a text file)

You can try look behinds as

/?<=\d{14}\s)[^']+/

Regex Demo

preg_match_all("/(?<=\\d{14}\\s)[^']+/", "01838723001603 TELO 155' ou '01838723009850 0608'.", $matches);

will give output as

Array ( [0] => Array 
                 ( [0] => TELO 155 
                   [1] => 0608 ) 
      ) 

This should work for you:

<?php

    $data = "01838723009850 0608";  //01838723001603 TELO 155
    preg_match_all('/\d{14}\s?(.*?)$/', $data, $result);
    echo $result[1][0];

?>

Output:

0608  //TELO 155
