IntlChar::isMirrored

(PHP 7, PHP 8)

IntlChar::isMirrored — Check if code point has the Bidi_Mirrored property

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

Determines whether the code point has the Bidi_Mirrored property.

This property is set for characters that are commonly used in Right-To-Left contexts and need to be displayed with a "mirrored" glyph.

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}")

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

示例 #1 Testing different code points

<?php
var_dump(IntlChar::isMirrored("A"));
var_dump(IntlChar::isMirrored("<"));
var_dump(IntlChar::isMirrored("("));
?>

以上示例会输出：

bool(false)
bool(true)
bool(true)
