Question

我想替换 unicode \ u00a0 与 php 中的实际数据。

示例：NSDictionary *environment = [[NSProcessInfo processInfo] environment];

Answer 1

\u00a0是NO-BREAK SPACE

要解码escape sequence中的任何 PHP，您可以使用此功能：

function unicodeString($str, $encoding=null) {
    if (is_null($encoding)) $encoding = ini_get('mbstring.internal_encoding');
    return preg_replace_callback('/\\\\u([0-9a-fA-F]{4})/u', create_function('$match', 'return mb_convert_encoding(pack("H*", $match[1]), '.var_export($encoding, true).', "UTF-16BE");'), $str);
}
echo unicodeString($str);

如果您只需要替换单 escape sequence，请使用：

$str = str_replace("\u00a0", " ", $str);
echo $str;
