Alnum

• Alnum()
• Alnum(string ...$additionalChars)

Validates whether the input is alphanumeric or not.

Alphanumeric is a combination of alphabetic (a-z and A-Z) and numeric (0-9) characters.

v::alnum()->validate('foo 123'); // false
v::alnum(' ')->validate('foo 123'); // true
v::alnum()->validate('100%'); // false
v::alnum('%')->validate('100%'); // true
v::alnum('%', ',')->validate('10,5%'); // true

You can restrict case using the Lowercase and Uppercase rules.

v::alnum()->uppercase()->validate('example'); // false
