    (PHP 7, PHP 8)

    IntlChar::totitle — Make Unicode character titlecase

    Description

    public static IntlChar::totitle(int|string $codepoint): int|string|null

    The given character is mapped to its titlecase equivalent. If the character has no titlecase equivalent, the original character itself is returned.

    Parameters

    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}")

    Return Values

    Returns the Simple_Titlecase_Mapping of the code point, if any; otherwise the code point itself. Returns null on failure.

    The return type is int unless the code point was passed as a UTF-8 string, in which case a string is returned. Returns null on failure.

    Examples

    Example #1 Testing different code points

    <?php
    var_dump    (IntlChar::totitle("DŽ"));
    var_dump(IntlChar::totitle("dž"));
    var_dump(IntlChar::totitle("Φ"));
    var_dump(IntlChar::totitle("φ"));
    var_dump(IntlChar::totitle("1"));
    var_dump(IntlChar::totitle("ᾳ");
    var_dump(IntlChar::totitle(ord("A")));
    ?>

    The above example will output:

    string(1) "Dž"
string(1) "Dž"
string(2) "Φ"
string(2) "φ"
string(1) "1"
string(1) "ᾼ"
int(65)
