IntlChar::totitle()

版本：php7

(PHP 7)

Make Unicode character titlecase

说明

The given character is mapped to its titlecase equivalent. If the character has no titlecase equivalent, the original character itself is returned.

参数

The integer codepoint value(e.g.0x2603forU+2603 SNOWMAN), or the character encoded as a UTF-8 string(e.g."u{2603}")

返回值

Returns the Simple_Titlecase_Mapping of the code point, if any; otherwise the code point itself.

The return type will be integer unless the code point was passed as a UTF-8 string, in which case a string will be returned.

范例

Testing different code points

以上例程会输出：

string(1) "A"
string(1) "A"
string(2) "Φ"
string(2) "Φ"
string(1) "1"
int(65)
int(65)
