Question

OK I’m not great with PHP but I’m learning so stay with me here.

I have an email address that all email received is piped to a php script which then stores the headers message subject etc in a database.

This works Fine but what I need to do is search the header for the senders server IP and then put that into a variable.

Answer 1

Use regular expressions.

i.e.

if (preg_match('/\(\[((\d){1,3}\.(\d){1,3}\.(\d){1,3}\.(\d){1,3})\]\)/i', $string, $matches))
{
    print_r($matches);
}
