Validation::hankaku
Check half-width characters
Description
public boolean Validation::hankaku( string $name, mixed $value, [ mixed $code = '' ] )
Valid when the value contains no multi-byte character (the byte length equals the character length).
An empty value ('', null, '0', whitespace only) is not checked and returns true: combine with Validation::required when the field is required. When $name already has an error, the check is skipped and returns false, so only the first error of each field is kept.
Arguments

|---|---|---|---|
| $name | string | Field name (key of the error message) | |
| $value | mixed | Value to check | |
| $code | mixed | '' | Error code, array of error code and parameters, or error message (see Configuration) |
