Php WeChat public development: how to obtain information about nearby hotels

This article mainly introduces the php public development method for getting information about surrounding hotels, and involves the application skills of the public platform on geographic information, which has some reference value, for more information about how to obtain information about nearby hotels, see examples in this article. Share it with you for your reference. The specific analysis is as follows:

After paying attention to the public, you can send a reply to the location information, and then you can reply to the list of nearby hotels. next I will introduce you to how php can be used to implement this function. the code is as follows:

The code is as follows:

<? Php
// Receive the submitted information
$ Signature = $ _ GET ['signature'];
$ Timestamp = $ _ GET ['timestamp'];
$ Nonce = $ _ GET ['nonce '];
$ Echostr = $ _ GET ['echostr'];
$ Token = "bitsCN.com ";
// Determine website access

// Sort the dictionary
$ Arr = array ($ token, $ timestamp, $ nonce );

Sort ($ arr );

// Complete String concatenation and sha1 encryption
$ Result = sha1 (join ($ arr ));
// Determine whether the generated string and $ signature are equal. if they are equal, $ echostr is output directly, so that the website access is successful.
If ($ result = $ signature ){
Echo $ echostr;
}

// Receive information received by the public account
$ Poststr = $ GLOBALS ["HTTP_RAW_POST_DATA"];

$ XmlObj = simplexml_load_string ($ poststr, 'simplexmlelement', LIBXML_NOCDATA );
$ ToUserName = $ xmlObj-> ToUserName;
$ FromUserName = $ xmlObj-> FromUserName;
$ CreateTime = $ xmlObj-> CreateTime;
$ MsgType = $ xmlObj-> MsgType;
$ Content = $ xmlObj-> Content;

If ($ MsgType = 'location '){
$ Location_X = $ xmlObj-> Location_X;
$ Location_Y = $ xmlObj-> Location_Y;
$ Scale = $ xmlObj-> Scale;
$ Label = $ xmlObj-> Label;

$ Urlstr = "http://api.map.baidu.com/place/v2/search? & Query = hotel & location = ". $ Location_X. ",". $ Location_Y. "& radius = 5000 & output = json & ak = DESY8unmZnUlLB0mlowjuiRr"; // Here, the ak parameter requires the serial number of the individual Baidu developer. you can apply for it on your own.
$ Jsonstr = file_get_contents ($ urlstr );
$ Json = json_decode ($ jsonstr, true );

$ Pic_640 = "http://api.map.baidu.com/staticimage? Width = 640 & height = 320 & center = ". $ Location_Y. ",". $ Location_X. "& zoom = 15 & markers = ". $ Location_Y. ",". $ Location_X. "& markerStyles = l ,";
$ Pic_80 = "http://api.map.baidu.com/staticimage? Width = 80 & height = 80 & center = ". $ Location_Y. ",". $ Location_X. "& zoom = 15 & markers = ". $ Location_Y. ",". $ Location_X. "& markerStyles = l ,";
$ P_640 = file_get_contents ($ pic_640 );
File_put_contents ('./images/640 _'. $ FromUserName. ". png", $ p_640 );
$ P_80 = file_get_contents ($ pic_80 );
File_put_contents ('./images/80 _'. $ FromUserName. ". png", $ p_80 );
Echo pic_send ($ json ['result']);
}
Function pic_send ($ arr ){
Global $ ToUserName, $ FromUserName;
$ Str ="
".$FromUserName."
".$ToUserName."
". Time ()."
news
". Count ($ arr )."
";
Foreach ($ arr as $ k =>$ v ){
If ($ k = 0 ){
$ Picurl = "http://bitsCN.com/weixin/images/640_". $ FromUserName. ". png ";
} Else {
$ Picurl = "http://bitsCN.com.net/weixin/images/80_". $ FromUserName. ". png ";
}
$ Str. ="

<! [CDATA [". $ v ['name']. "Address :". $ v ['address']. "Phone :". $ v ['telphone']. "]>
".$v['name']." 地址：".$v['address']." 电话:".$v['telephone']."
".$picurl."
http://api.map.baidu.com/place/detail&#63;uid=".$v['uid']."&output=html&src=".$v['name']."&output=html
";
}
$ Str. =" ";
Return $ str;
}
?>

I hope this article will help you with php programming.
