IntlChar::isUUppercase

(PHP 7)

IntlChar::isUUppercase — Check if code point has the Uppercase Unicode property

Description

public static bool IntlChar::isUUppercase ( mixed $codepoint )

Check if a code point has the Uppercase Unicode property.

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

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

Parameters

codepoint

The integer codepoint value (e.g. 0x2603 for U+2603 SNOWMAN), or the character encoded as a UTF-8 string (e.g. "\u{2603}")

Return Values

Returns TRUE if codepoint has the Uppercase Unicode property, FALSE if not.

Examples

Example #1 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")
?>

​

The above example will output:

​

​

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