Regex Tester & Validator

This regex matches Chinese mobile phone numbers (11 digits starting with 1, second digit 3/4/5/7/8) that are immediately followed by a parenthesized label or name. It tolerates surrounding whitespace and both ASCII and fullwidth parentheses, making it useful for parsing contact lists, log files, or tabular data where each entry contains a number and a name in parentheses. The 'gm' flags enable matching across multiple lines.
