php - Get the string to the right of another string -

-

been working bit on chat/shoutbox of mine, , have row in users table called muted (0 not muted, 1 muted). want is, when type !mute <target> should update row <target> , set muted 1.

i know how check if string contains !mute, this:

if (strpos($sboxmsg,'!mute') !== false) {  }

the thing is, have no idea how right of !mute. , need turn right variable can use in query later on.

example:

!mute nick

then store nick in variable called eg. $variable1

is possible? appreciated!

use 

$variable1 = preg_replace('/^\!mute\s+/', '', $whatever_input);
