The IntlChar::isULowercase() function is used to check whether the entered character is a Lowercase Unicode character or not.SyntaxIntlChar::isULowercase( val )Parametersval − The character to be checked encoded as a UTF-8 string.ReturnThe IntlChar::isULowercase() function returns TRUE if the entered value is a Lowercase Unicode character.ExampleThe following is an example −OutputThe following is the output −bool(true) bool(false) NULL

The IntlChar::isISOControl() function is used to check whether the entered value is an ISO control code character or not.SyntaxIntlChar::isISOControl(val)Parametersval − A character or integer value encoded as a UTF-8 string.ReturnThe IntlChar::isISOControl() function returns TRUE if the entered value is an ISO control code character.ExampleThe following is an example −OutputThe following is the output −bool(false) bool(true) bool(false) bool(false)

The IntlChar::isIDIgnorable() function is used to determine whether the entered value is an ignorable character or not.Syntaxbool IntlChar::isIDIgnorable(val)Parametersval − A character or integer value encoded as UTF-8 string.ReturnThe IntlChar::isIDIgnorable()function returns TRUE if the val is an ignorable character.ExampleThe following is an example −OutputThe following is the output −bool(false) bool(true) bool(false)

The IntlChar::isUWhiteSpace() function check whether the given input character is a WhiteSpace Unicode character or not.SyntaxIntlChar::isUWhiteSpace(val)Parametersval − A character or integer value encoded as a UTF-8 string.ReturnThe IntlChar::isUWhiteSpace() function returns TRUE if the val is a WhiteSpace Unicode character.ExampleThe following is an example −OutputThe following is the output −bool(true) bool(false) bool(false)

The IntlChar::charAge() function is used to compute the age of the entered value, which is the Unicode version. This is when the value was first designated or assigned a character.Syntaxarray IntlChar::charAge( val)Parametersval − A character or integer value encoded as a UTF-8 string.ReturnThe IntlChar::charAge() function returns the Unicode version number of an array, if true.ExampleThe following is an example −OutputThe following is the output −array(4) { [0]=> int(0) [1]=> int(0) [2]=> int(0) [3]=> int(0) }

The IntlChar::charName()function gets the name of a Unicode character.Syntaxstring IntlChar::charName( val [, choice = IntlChar::UNICODE_CHAR_NAME] )Parametersval − An integer value or character encoded as UTF-8 string.choice − The following are the constant conditions −IntlChar::UNICODE_CHAR_NAMEIntlChar::CHAR_NAME_ALIASIntlChar::CHAR_NAME_CHOICE_COUNTIntlChar::UNICODE_10_CHAR_NAMEIntlChar::EXTENDED_CHAR_NAMEReturnThe IntlChar::charName() function returns the corresponding name of input data. For no name of character, an empty string is returned.ExampleThe following is an example −OutputThe following is the output −string(9) "AMPERSAND" string(9) "AMPERSAND"ExampleLet us see another example −OutputThe following is the output −string(22) "LATIN CAPITAL LETTER K" string(22) "LATIN CAPITAL LETTER K"ExampleLet us see one more example with a different input value −OutputThe following is the output ...
