PHPの「一般的な識別子のセキュリティプロファイル」でUnicode文字が「許可」されているかどうかを知る方法？

Question

この文書General Security Profile for Identifiersは、（他の条件のなかでも）Unicode文字が識別子の一部である資格があるため、ここでは「許可」のステータスが「xidmodifications.txt」であることを示しています。ステータスが「Restricted」のキャラクターは対象外です。

PHP 5でこのプロパティにアクセスする方法はありますか？ 私が特に必要としているのは、すべての文字がUnicode Consortiumに適しているかどうかを文字列で知ることです。

Answer 1

非常に構造化されたテキストドキュメントがあるようです。正規表現に最適です！

^([0-9A-F]+)(\.\.[0-9A-F]+)?\s*;\sAllowed 

私はそのファイルに対して正規表現を実行しました（gとmの修飾子付き）、私はたくさんのマッチを得ました。しかし、私は誰も手でこれらを一致させることを望んでいる疑いがあります。もっと正規表現！

だから私は、この正規表現を実行した：それはのように見えるので、これはインスタンスの約半分置き換え

\\x{$1} 

：

^([0-9A-F]+) 

と、この交換

\x{0030} 
..0039 
\x{0041} 
..005A 
\x{005F} 
\x{0061} 
..007A 

しかし、我々正規表現が必要です...

\.\.([0-9A-F]+) 

と、この交換：

-\\x{$1} 

は、今では次のようになります。

\x{0030} 
-\x{0039} 
\x{0041} 
-\x{005A} 
\x{005F} 
\x{0061} 
-\x{007A} 

ほとんど... で別の正規表現をすべて\sを除去した後、私は[と]を追加することができます私は...

解決策

これはcharクラスなので、他の場合と同じように使用してください。警告：非常に長い...

あなたはこのようにそれを使用することができます（ここで、 "正規表現" 上記のコードはある）：

$re = "/regex/u"; 

$str = "t";  
echo preg_match($re, $str, $matches);//1 

echo "<br>"; 

$str = "(̶";
