一个PHP高性能、多并发、restful的工具库（基于multi_curl）

   This is high performance curl wrapper written in pure PHP. It's compatible with PHP 5.4+ and HHVM. Notice that libcurl version must be over 7.36.0, otherwise timeout can not suppert decimal.
 
   这是一个高性能的PHP封装的HTTP Restful多线程并发请求库，参考借鉴了httpresful 、multirequest等优秀的代码。它与PHP .4和hhvm兼容。 注意，libcurl版本必须>=7.36.，否则超时不支持小数。

　　大家好，今天的主角是它： https://github.com/sinacms/MultiHttp ，这是本人写的一个curl工具库，在生产中十分好用，所以拿出来分享给大家，欢迎大家提issue/merge request， 点赞什么的。

options选项有：
 
   'url'             => 'CURLOPT_URL',
   'debug'           => 'CURLOPT_VERBOSE',//for debug verbose
   'method'          => 'CURLOPT_CUSTOMREQUEST',
   'data'            => 'CURLOPT_POSTFIELDS', // array or string , file begin with '@'
   'ua'              => 'CURLOPT_USERAGENT',
   'timeout'         => 'CURLOPT_TIMEOUT', // (secs) 0 means indefinitely
   'connect_timeout' => 'CURLOPT_CONNECTTIMEOUT',
   'referer'         => 'CURLOPT_REFERER',
   'binary'          => 'CURLOPT_BINARYTRANSFER',
   'port'            => 'CURLOPT_PORT',
   'header'          => 'CURLOPT_HEADER', // TRUE:include header
   'headers'         => 'CURLOPT_HTTPHEADER', // array
   'download'        => 'CURLOPT_FILE', // writing file stream (using fopen()), default is STDOUT
   'upload'          => 'CURLOPT_INFILE', // reading file stream
   'transfer'        => 'CURLOPT_RETURNTRANSFER', // TRUE:return string; FALSE:output directly (curl_exec)
   'follow_location' => 'CURLOPT_FOLLOWLOCATION',
   'timeout_ms'      => 'CURLOPT_TIMEOUT_MS', // milliseconds,  libcurl version > 7.36.0 ,

　　

　   怎么样，什么人性、直观吧，

　　另外，建议大家用最新stable版本， 有很多好用的feature, 比如 expectsJson() 会直接验证response是json，并解析成php array( or hashmap)，更多特性请看tests目录的使用。

　　欢迎大家使用它。

　　我有空会补充些详细说明。
