(PHP 7, PHP 8)

IntlChar::isULowercase — Check if code point has the Lowercase Unicode property

Descrizione

public static IntlChar::isULowercase(int|string $codepoint): ?bool

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.

Elenco dei parametri

codepoint

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

Valori restituiti

Returns true if codepoint has the Lowercase Unicode property, false if not. Returns null on failure.

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"));
?>
