CURLOPT_HTTPHEADER => ["Cookie: $cookie"],
CURLOPT_POSTFIELDS => ['b64_data' => base64_encode(file_get_contents('./img.jpg'))],

如果要用 http://picupload.service.weibo.com/interface/pic_upload.php?mime=image%2Fjpeg&data=base64&url=0&markpos=1&logo=&nick=0&marks=1&app=miniblog 这个 URL 的话
POST 参数必须是 b64_data，值为经过 base64 编码后的字符串
如果要使用 pic1 参数的话，则要用 multipart 方式进行上传，且 URL 中必须包含 cb 参数，cb 参数的值为 http://weibo.com/aj/static/upimgback.html?_wv=5&callback=STK_ijax_ 加(js)时间戳
2种方法相比较的话，我个人倾向于 multipart 方法，因为 base64 编码会使上传文件的体积增加 1/3，不仅上传时间要更久，流量消耗也多了 1/3

###[表增加索引而不影响使用](https://segmentfault.com/q/1010000008339569)
```js
这个需要看你用的mysql版本以及使用的存储引擎是否是innodb
mysql的5.1如果使用innodb插件或者是5.5版本使用innodb引擎有InnoDB Fast Index Creation，对于新建或者删除二级索引，不用复制表，效率有很大提高，但是只允许读操作，不允许修改操作。
而5.6版本中引入的innodb-online-ddl，在新建或者删除二级索引的时候可以并发执行DML语句，除了建索引操作会消耗硬件资源，不影响表的正常使用。
具体方案需要你根据数据库和存储引擎的情况来选择，如果版本满足，使用online ddl特性可以满足需求

在__set()方法中，你设置__set("a", 1),$name作为局部变量，会转化为"a", $this->$name等价于$this->a,
在__destruct()中, 局部变量$property未定义，会有一个默认值""，属性值不能为空字符串，所以报错。

###[订单逻辑](https://segmentfault.com/q/1010000008334556)
当订单生成的时候，立即扣除库存
订单超过24小时，未付款，自动取消订单，恢复库存。
没有库存的时候，不能生成订单。

```js
https://github.com/iamcal/php-emoji https://github.com/mc-zone/emoji-code Emoji表情的各种编码
emoji unicode编码数据表，可以与 github.com/iamcal/php-emoji 的样式表和图片相结合
使用 json_encode($str) 将其进行JSON编码，此时消息中的表情、中文等字符将会被转为unicode编码显示
“你好 hello 123″ 将被编码为” \u4f60\u597d \ue415 hello 123 “
字符中的\ue415就是一个emoji表情，此时我们就可以对字符进行正则判断来筛选出哪些是emoji表情了。我的做法是把emoji的unicode字符串反斜杠转义，然后再将字符json_decode还原，这样就可以将除了emoji之外的字符还原（不会影响到中文等其他字符），只留下emoji的unicode码。
$str = preg_replace("#(\\\ue[0-9a-f]{3})#ie","addslashes('\\1')",$str); 选择了 ue000 – uefff 之间的字符视为emoji
$text = "你好 hello 123"; //可以为收到的微信消息，可能包含二进制emoji表情字符串
$tmpStr = json_encode($text); //暴露出unicode
//$tmpStr = preg_replace("#(\\\ue[0-9a-f]{3})#ie","addslashes('\\1')",$tmpStr); //将emoji的unicode留下，其他不动
$tmpStr = preg_replace_callback("#(\\\ue[0-9a-f]{3})#i",function($m){return addslashes($m[1]);},$tmpStr);
$text = json_decode($tmpStr);
echo $text;//你好 \ue415 hello 123
$text = "你好 \ue415 hello 123"; //可以为将要发送的微信消息，包含emoji表情unicode字符串，需要转为utf8二进制字符串
$text = preg_replace("#\\\u([0-9a-f]+)#ie","iconv('UCS-2','UTF-8', pack('H4', '\\1'))",$text); //对emoji unicode进行二进制pack并转utf8
echo $text;//你好 hello 123
