【微信公众平台开发】百度周边搜索接口php封装

现在微信公众平台很多娱乐的，都有用到周边搜索功能，研究下比较简单，通过百度周边搜索接口封装如下：

调用格式：

$wechatBaiduAPI = new WechatBaiduAPI();$ret = $wechatBaiduAPI->Place_search($str_key,$location['x'].",".$location['y'] );

参数说明：

$query：搜素关键词

$location： 地理位置经纬度

$radius： 搜索半径

<?php class WechatBaiduAPI{		private $api_server_url;		private $auth_params;				public function __construct()		{			$this->api_server_url = "http://api.map.baidu.com/place/v2/";			$this->auth_params = array();			$this->auth_params['ak'] = "11ffd27d38deda622f51c9d314d46b1";		}				//http://api.map.baidu.com/place/search?&query=眼镜&location=39.915,116.404&radius=3000&output=json&key=37492c0ee6f924cb5e934fa08c6b1676		public function Place_search($query, $location, $radius=3000)		{			return $this->call("search", array("output" =>json, "query" => $query,"page_size" =>10, "page_num" => 0,					 "scope" => 2,"location" => $location, "radius" => $radius));		}				protected function call($method, $params = array())		{			$params = array_merge($this->auth_params, $params);			$url = $this->api_server_url . "$method?".http_build_query($params);						$ch = curl_init();			curl_setopt($ch, CURLOPT_URL, $url);			curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);						$data = curl_exec($ch);			curl_close($ch);						$result = null;						$result = json_decode($data,true);						return $result;		}			}

注意：代码里面的ak，是百度密钥，每个百度帐号都有一个唯一的ak，具体自己可以百度！

$this->auth_params['ak'] = "11ffd27d38deda622f51c9d314d46b1";
