PHP Regex, Get last word after different characters

Question

I'm trying to find out how to get the last word of a string, However the character im trying to match it too isn't always the same. For example

This is a file (USA) -LastWord
This is another file (EUR) ~LastWord
This is another different file (JPN) LastWord

How can i match against this? I always want to just return "LastWord"

I will suggest using:

/\b\w+(?=\W*$)/m

RegEx Demo

This will match last word optionally followed by 0 or more non-word characters like period. (See demo)

You could try the below regex to get the last word.

\w+$

$ matches the end of a line. \w+ matches one or more word characters. Add multiline m modifier whenever anchors are used.

DEMO

$re = "/\\w+$/m";
$str = "This is a file (USA) -LastWord\nThis is another file (EUR) ~LastWord\nThis is another different file (JPN) LastWord";
preg_match_all($re, $str, $matches);

Doesn't seem to be returning any results.

explanation that $ is end of string and \w is a-z group, + is one or more char, you're missing i modifier

you must need to add multiline modifier.
