版本:php7
(PHP 7)
Check if code point has the Lowercase Unicode property
说明
public static IntlChar::isULowercase(mixed $codepoint): bool
Check if a code point has the Lowercase Unicode property.
This is the same asIntlChar::hasBinaryProperty($codepoint, IntlChar::PROPERTY_LOWERCASE)
Note:This is different than IntlChar::islower() 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 Lowercase Unicode property,FALSE
if not.
范例
Testing different code points
<?php var_dump(IntlChar::isULowercase("A")); var_dump(IntlChar::isULowercase("a")); var_dump(IntlChar::isULowercase("Φ")); var_dump(IntlChar::isULowercase("φ")); var_dump(IntlChar::isULowercase("1")); ?>
以上例程会输出:
bool(false) bool(true) bool(false) bool(true) bool(false)
