PHP中json_encode中文被Unicode编码的解决办法

先对需要处理的数组的键值分别做urlencode处理，然后json_encode，最后做urldecode处理 。

<code><span><span>function</span><span>encode_json</span><span>(<span>$str</span>)</span> {</span><span>return</span> urldecode(json_encode(url_encode(<span>$str</span>)));   
}

<span>/**
 *@desc 递归的处理数组中的每一个键值对
 */</span><span><span>function</span><span>url_encode</span><span>(<span>$str</span>)</span> {</span><span>if</span>(is_array(<span>$str</span>)) {
        <span>foreach</span>(<span>$str</span><span>as</span><span>$key</span>=><span>$value</span>) {
            <span>$str</span>[urlencode(<span>$key</span>)] = url_encode(<span>$value</span>);
        }
    } <span>else</span> {
        <span>$str</span> = urlencode(<span>$str</span>);
    }

    <span>return</span><span>$str</span>;
}
</code>

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });
