StartsWith

• StartsWith(mixed $value)
• StartsWith(mixed $value, bool $identical)

Validates whether the input starts with a given value.

This validator is similar to Contains, but validates only if the value is at the beginning of the input.

For strings:

v::startsWith('lorem')->isValid('lorem ipsum'); // true

For arrays:

v::startsWith('lorem')->isValid(['lorem', 'ipsum']); // true

true may be passed as a parameter to indicate identical comparison instead of equal.

Message template for this validator includes {{startValue}}.
