このデータをjsonとして転送しようとしていますが、検証されません。\x3cこれは、のような文字をより長い6文字の形式にする必要があるためだと思います（ https://www.rfc-editor.org/rfc/rfc4627のセクション2.5を参照してください。-文字列）。

これは実際に問題ですか？もしそうなら、フォーマットを変換する良い方法はありますか？

\xは通常 16 進数を表し、\uは Unicode を表します。あなたの質問は、Unicode または Unicode コードポイントとは何の関係もありません。

はmax であり、ASCII 範囲であるchr()ため、安全に使用できます。\xFF255

function weird_answer_to_weird_question($string)
{
    return preg_replace_callback('#\\\\x([[:xdigit:]]{2})#ism', function($matches)
    {
        return chr(hexdec($matches[1]));
    },
    $string);
}

出力：

「... \n医学用語に関する十分な知識と、40 wpm のタイピング スキル。優れたコミュニケーションと ... 機密および/または機密 の医療情報へのアクセスが必要です。意思決定および ... におけるリーダーシップ スキルを実証する必要があります。」

PS

それを二重にエンコードする$string = str_replace('\n', "\n", $string);ため、または同様のことも行う必要があります。指摘してくれた@netcoderjson_encode()に感謝します。

どうですか :

echo iconv('ASCII', 'UTF-8', "Proficient knowledge of \x3cstrong\x3emedical\x3c/strong\x3e terminology");
// returns Proficient knowledge of <strong>medical</strong> terminology
$jsonString = "... \n Yes \n \n \n The \x3cstrong\x3eMedical\x3c/strong\x3e Assistant performs patient screening care under the direction of the \x3cstrong\x3eMedical\x3c/strong\x3e Director/On-site provider including, but not limited to, EKG’s. ...";
$jsonString = str_replace(array('’'), array("'"), $jsonString);
echo iconv('ASCII', 'UTF8//IGNORE//TRANSLIT', nl2br($jsonString));
// returns ... <br>Yes <br><br><br>The <strong>Medical</strong> Assistant performs patient screening care under the direction of the <strong>Medical</strong> Director/On-site provider including, but not limited to, EKG's. ...

わかりました、これでうまくいきます：

/**
 * Converts all UTF-8 Units ( \xXX ) back into ascii characters.  
 * 
 * @param string $input   String which includes some UTF-8 units
 * @return string
 */
function convertUTF8Units($input) {
    include $path;
    $part = "";
    $output = $input;
    $len = strlen($input)-4;

    for($i=0; $i<=$len; $i++) {
      $part = substr($input, $i, 4);

      if ((substr($part, 0, 2) === "\\x")) {          
        $raw = hex2bin( $part );
        $raw = trim($raw);
        $pattern = "/\\".$part."/";
        $output = preg_replace($pattern, $raw, $output);
      }

    }
    return $output;
}

/**
 * Function to convert a hex code back to ascii string.  Taken from 
 * http://devcorner.georgievi.net/pages/programming/php/hex2bin-php.
 * 
 * @param string $hex_string   String of format: \xXX
 * @return string
 */
define('HEX2BIN_WS', " \t\n\r");
function hex2bin($hex_string) {
  $pos = 0;
    $result = '';
    while ($pos < strlen($hex_string)) {
      if (strpos(HEX2BIN_WS, $hex_string{$pos}) !== FALSE) {
        $pos++;
      } 
    else {
        $code = hexdec(substr($hex_string, $pos, 2));
      $pos = $pos + 2;
        $result .= chr($code); 
      }
    }
    return $result;
}

私は正確に何に変換しているのかについて少し曖昧です。私が確信しているのは、すべての JSON バリデーターを通過することだけです。この UTF-8 を追求しているうちに、UTF-8 単位、2 進数、16 進値、および ASCII 文字がすべて出てきました。私は実際に違いを明確にすることはできませんし、これらの関数の入力、変換、または出力が何であるかを明確に言うこともできません。

私のコードが何をしているかを誰かが教えてくれますか? :P
