(PHP 7, PHP 8)
IntlChar::isULowercase — Check if code point has the Lowercase Unicode property
Check if a code point has the Lowercase Unicode property.
This is the same as IntlChar::hasBinaryProperty($codepoint, IntlChar::PROPERTY_LOWERCASE)
Nota:
This is different than IntlChar::islower() and will return
true
for more characters.
codepoint
Um codepoint integer (por exemplo 0x2603
para U+2603 SNOWMAN), ou um caracter codificado como uma string UTF-8 (exemplo "\u{2603}"
)
Returns true
if
codepoint
has the Lowercase Unicode property, false
if not.
Exemplo #1 Testando codepoints diferentes
<?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"));
?>
O exemplo acima irá imprimir:
bool(false) bool(true) bool(false) bool(true) bool(false)
IntlChar::PROPERTY_LOWERCASE
