本文实例为大家分享了php微信百度天气预报的开发代码，供大家参考，具体内容如下
1.登录百度ak申请：http://lbsyun.baidu.com/apiconsole/key

2.实现天气信息功能

baiduWeather.php
$ak,
'location' => $location,
'output' => $output
  );

  $querystring = http_build_query($querystring_arrays);
  //生成sn
  $sn = md5(urlencode($uri.'?'.$querystring.$sk));
  $targetUrl = sprintf($url,$ak,urlencode($location),$output,$sn);

  $ch = curl_init();
  curl_setopt($ch,CURLOPT_URL,$targetUrl);
  curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
  $result = curl_exec($ch);
  curl_close($ch);
  $result = json_decode($result,true);

  if($result["error"]!=0){
return $result["status"];
  }

  $curHour = (int)date('H',time());
  $weather = $result["results"][0];
  $weatherArray[]=array("Title"=>$weather['currentCity']."天气预报","Description"=>"","

icUrl"=>"","Url"=>"");
for($i = 0;$i
$weather["weather_data"][$i]["data"]."\n".
$weather["weather_data"][$i]["weather"].
$weather["weather_data"][$i]["wind"].
$weather["weather_data"][$i]["temperature"],
"Description"=>"",
"

icUrl"=>(($curHour>=6)&&($curHour""
);
  }
  return $weatherArray;
}
3.实现天气消息事件
responseMsg();
}else{
$wechatObj->valid();
}

class wechatCallbackapiTest
{
//验证签名
public function valid()
{
  $echoStr = $_GET["echostr"];
  if($this->checkSignature()){
header('content-type:text');
echo $echoStr;
exit;
  }
}

public function checkSignature(){
  $signature = $_GET["signature"];
  $timestamp = $_GET["timestamp"];
  $nonce = $_GET["nonce"];
  $token = TOKEN;
  $tmpArr = array($token, $timestamp, $nonce);
  sort($tmpArr);
  $tmpStr = implode($tmpArr);
  $tmpStr = sha1($tmpStr);
  if($tmpStr == $signature) {
return true;
  }else{
return false;
  }
}

//响应消息
public function responseMsg()
{
  $postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
  if (!empty($postStr)){
$this->logger("R ".$postStr);
$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
$RX_TYPE = trim($postObj->MsgType);

//消息类型分离
switch ($RX_TYPE)
{
case "event":
   $result = $this->receiveEvent($postObj);
   break;
case "text":
   $result = $this->receiveText($postObj);
   break;
default:
   $result = "unknown msg type: ".$RX_TYPE;
   break;
}
echo $result;
  }else {
echo "";
exit;
  }
}

//接收事件消息
public function receiveEvent($object)
{
  $content = "";
  switch ($object->Event)
  {
case "subscribe":
$content = "欢迎关注Nicky的公众号 ";
$content .= (!empty($object->EventKey))?("\n来自二维码场景 ".str_replace("qrscene_","",$object->EventKey)):"";
break;
case "unsubscribe":
$content = "取消关注";
break;
  }
  $result = $this->transmitText($object, $content);
  return $result;
}

//接收文本消息
public function receiveText($object)
{
  $keyword = trim($object->Content);

  //自动回复模式

  if (strstr($keyword, "天气")){
$city = str_replace('天气','',$keyword);
include("baiduweather.php");
$content = getWeatherInfo($city);
  }
  $result = $this->transmitNews($object, $content);
  return $result;
}

//回复图文消息
public function transmitNews($object, $newsArray)
{
  if(!is_array($newsArray)){
return;
  }
  $itemTpl = "

  [U][/U]

";
  $item_str = "";
  foreach ($newsArray as $item){
$item_str .= sprintf($itemTpl, $item['Title'], $item['Description'], $item['PicUrl'], $item['Url']);
  }
  $xmlTpl = "

%s

%s

$item_str
";

  $result = sprintf($xmlTpl, $object->FromUserName, $object->ToUserName, time(), count($newsArray));
  return $result;
}

//日志记录
public function logger($log_content)
{
  if(isset($_SERVER['HTTP_APPNAME'])){ //SAE
sae_set_display_errors(false);
sae_debug($log_content);
sae_set_display_errors(true);
  }else if($_SERVER['REMOTE_ADDR'] != "127.0.0.1"){ //LOCAL
$max_size = 10000;
$log_filename = "log.xml";
if(file_exists($log_filename) and (abs(filesize($log_filename)) > $max_size)){unlink($log_filename);}
file_put_contents($log_filename, date('H:i:s')." ".$log_content."\r\n", FILE_APPEND);
  }
}

}
?>
