Hi.

I'm trying to check if a string has a list of numbers separed by commas. Any element separed by comma could be also an asterisk (*) instead of a number.

Here some examples of valid expressions:
123,456,23
123,*,23
345
*
*,123,*,456

And some non-valid expressions:
*,a,*
*,123,

I'm trying this regular expression:
/[0-9|\*](,([0-9]|\*)*/

I tested it on this page: https://es.functions-online.com/preg_match.html
however it seems it always return 1. Isn't preg_match the correct function to call for this purpose? What I'm doing wrong?

Thank you.
