(PHP 7)
Check if code point has the Uppercase Unicode property
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}")
Returns:
Returns TRUE
if codepoint
has the Uppercase Unicode property, FALSE
if not.
Examples:
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)
