Validation::katakana

Check Katakana characters for Japanese language

Description

public boolean Validation::katakana( string $name, mixed $value, [ mixed $code = '', boolean $zenkakuFlag = false ] )

By default the value must contain only half-width Katakana and half-width symbols (｡ to ﾟ), spaces, (, ) and .. With $zenkakuFlag it must contain only full-width Katakana (ァ-ヶ), ー and full-width spaces.

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	Data type	Default	Remarks
$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)
$zenkakuFlag	boolean	false	true: full-width Katakana only / false: half-width Katakana only
