Filter textfile columns

[dotty]

Hi,

I have a php page which logs date/time and username of members who log in to a database. I want to filter the results so the results for one member only can be viewed.
Does anyone know how to filter the columns of a textfile?

any help appreciated

Is this what you mean?

$lines = file($text_file);
foreach ($lines as $each_line) {
    if (strpos($each_line, 'Jim') !== false) {
        $jim_arr[] = $each_line;
    }
}
