1.命令行下将unicode转中文?

• 方法1

<code><span><?php</span><span><span>function</span><span>unicodeDecode</span><span>(<span>$name</span>)</span>{</span><span>$json</span> = <span>'{"str":"'</span>.<span>$name</span>.<span>'"}'</span>;
  <span>$arr</span> = json_decode(<span>$json</span>,<span>true</span>);
  <span>if</span>(<span>empty</span>(<span>$arr</span>)) <span>return</span><span>''</span>; 
  <span>return</span><span>$arr</span>[<span>'str'</span>];
}
<span>$name</span> = <span>'\u65b0\u6d6a\u5fae\u535a'</span>;
<span>echo</span> unicodeDecode(<span>$name</span>); <span>//输出： 新浪微博 </span></code>

• 方法2:

<code><span><span>function</span><span>replace_unicode_escape_sequence</span><span>(<span>$match</span>)</span> {</span><span>return</span> mb_convert_encoding(pack(<span>'H*'</span>, <span>$match</span>[<span>1</span>]), <span>'UTF-8'</span>, <span>'UCS-2BE'</span>);
}
<span>$name</span> = <span>'\u65b0\u6d6a\u5fae\u535a'</span>;
<span>$str</span> = preg_replace_callback(<span>'/\\\\u([0-9a-f]{4})/i'</span>, <span>'replace_unicode_escape_sequence'</span>, <span>$name</span>);
<span>echo</span><span>$str</span>; <span>//输出： 新浪微博 </span></code>
