Get post request method encapsulation in php

<span style="font-size:18px;">网站上的商城可以搭建ecshop实现，微信端的微商城也可以开发wap版商城，然后通过链接链到微信菜单上，这样实现起来就不需要远程调用数据了，但登陆上有个问题，在微信上进入微商城在用户体验上当然不需要再登陆只需要有微信openid即可。所以有个考虑是在微信端开发微商城，所以的数据是取自网站商城的，这时需要远程请求数据。
有了ihttp_request()方法后，可通过此方法获取远程数据</span>

The printed content is very detailed, even the header information is typed out, but we only need to care about the content in the content. This is the data we need to obtain
["content"]=>
string(241) "{" result":"success","msg":"","info":{"data_info":[{"goods_id":"1","last_modify":"1423937979"},{"goods_id":"2" ,"last_modify":"1425595831"},{"goods_id":"3","last_modify":"1423937959"},{"goods_id":"4","last_modify":"1423942862"}],"counts" :"4"}}"

The above introduces the encapsulation of the get post request method in PHP, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
