IntlChar::chr

(PHP 7, PHP 8)

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

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

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

This method complements IntlChar::ord().

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}")

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

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) "☃"
