IntlChar::isUUppercase()

版本：php7

(PHP 7)

Check if code point has the Uppercase Unicode property

说明

publicstaticIntlChar::isUUppercase(mixed $codepoint): bool

Check if a code point has the Uppercase Unicode property.

This is the same asIntlChar::hasBinaryProperty($codepoint, IntlChar::PROPERTY_UPPERCASE)

Note:

This is different than IntlChar::isupper() and will return TRUE for more characters.

参数

$codepoint

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 TRUE if$codepointhas the Uppercase Unicode property,FALSE if not.

范例

Testing different code points

<?php
var_dump(IntlChar::isUUppercase("A"));
var_dump(IntlChar::isUUppercase("a"));
var_dump(IntlChar::isUUppercase("Φ"));
var_dump(IntlChar::isUUppercase("φ"));
var_dump(IntlChar::isUUppercase("1"));
?>

以上例程会输出：

bool(true)
bool(false)
bool(true)
bool(false)
bool(false)
