IntlChar::isMirrored — Check if code point has the Bidi_Mirrored property
$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("("));
?>
以上例程会输出：
bool(false) bool(true) bool(true)
IntlChar::PROPERTY_BIDI_MIRRORED
