Question

Can someone help me with php regex that would scan a list of domains and remove any domains that have numbers, dashes, and over 15 characters long?

Answer 1

Loop over them and test with preg_match. As for regex, \d matches digits, and .{16,} will match strings that are 16 characters or longer. – will match the -, lol. You can use | as the OR operator.

Put it all together and you get:

preg_match('/\d|-|.{16,}/', $testString);
