Question

This is my attempt, but it’s not working. I’m so rusty at regex these days so I have no idea what’s wrong with it. Any help?

$pattern = '/-\$[.*]$/';

Answer 1

You need to put the * outside of the [] (or better yet, use a +).

Try '/-\$[0-9\.]+/':

$pattern = '/-\$[0-9\.]+/';

Or, if -$7.50 will always be at the end of the line:

$pattern = '/-\$[0-9\.]+$/';
