PHP Code to pull IP:Port from string with characters after the port #

Friday, July 4, 2014

I need a little help with this one and my RegEx knowledge is a little lacking with this one.

I have a proxy list that I'm trying to parse and separate the IP and port number from the string.

The string being read looks like this.(example 1) 2.103384 Китай high 05-07-2014 09:25:17

and sometimes look like (example 2)

When I use this code.

$output = (preg_split('/:/',$proxy));
$ip = $output['0'];
$port = $output['1'];

It works great when there is just a IP:Port like in example #2 but in example #1 its also grabbing everything past the space so the port number looks like "8081 2.103384 Китай high 05-07-2014 09:25:17"

Is there a regex pattern I can use to have it stop at a space if it see's one?
