How to use preg_match to search for symbols

How do i find matches with any of -+/* symbols using preg_match?

I try 

$stroke = '21+64';
$pattern = '/[+-/*]/';

preg_match($pattern, $stroke, $matches);
var_dump($matches);

but it doesn't work.. Thank you.

Have a try with that pattern: 

/[+\-\*]/

You have to "escape" the - and the *, and you do that with a preceding "back slash" (\).
