    IntlChar::chr — Return Unicode character by code point value

    说明

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

    Returns a string containing the character specified by the Unicode code point value.

    This function complements IntlChar::ord().

    参数

    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}")

    返回值

    A string containing the single character specified by the Unicode code point value, or null on failure.

    示例

    示例 #1 Testing different code points

    <?php
    $values     = ["A", 63, 123, 9731];
    foreach (    $values as $value) {
    var_dump(IntlChar::chr($value));
    }
    ?>

    以上示例会输出：

    string(1) "A"
string(1) "?"
string(1) "{"
string(3) "☃"
