The IntlChar::totitle() function is an inbuilt function in PHP which is used to check whether the input code point is a Unicode character titlecase or not.
Syntax:
mixed IntlChar::totitle( $codepoint )
Parameters: This function accepts a single parameter $codepoint which is mandatory. The $codepoint parameter is a character or integer value, which is encoded as a UTF-8 string.
Return Value: Returns the simple_Titlecase_Mapping of the code point, if any; otherwise the code point itself. The return type will be an integer unless the code point was passed as a UTF-8 string, in which case a string will be returned.

var_dump(IntlChar::totitle("G"));
// Input Capital letter codepoint
var_dump(IntlChar::totitle("g"));
// Input Capital letter codepoint
var_dump(IntlChar::totitle("a"));
// Input int char an identifier
// of codepoint value
var_dump(IntlChar::totitle("\u{00A0}"));
// Input symbolic space codepoint value
