如何使用AWK命令

Question

Below is what I am trying to do:

1. There is one PHP variable which contains a string.

   $indexvalue='hotmail.com; spf=none (sender IP is 1.1.1.23)';
   

2. I want to use an AWK command to get value none and IP value 1.1.1.23 in two different PHP variables.

How can this be done?

Answer 1

it really depends on the format of your string. which bits are always going to be in there and what bit change a guess based on what I have here

preg_match('/.*; spf=([^\s]*) \(sender IP is ([^)]*)\)/', $indexvalue, $matches);

after which $matches contains

Array
(
    [0] => hotmail.com; spf=none (sender IP is 1.1.1.23)
    [1] => none
    [2] => 1.1.1.23
)

This assumes that spf= will always be present, that after the domain name there will be a ; and that the ip is announced by sender IP is.
