IntlChar::isUUppercase — Check if code point has the Uppercase Unicode property
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.
codepoint
La valeur codepoint de type entier
(i.e. 0x2603

(i.e. "\u{2603}"
)
Returns true
if
codepoint
has the Uppercase Unicode property, false
if not. Returns null
on failure.

<?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"));
?>
