现在天气预报网站都提供了解api来调用了,我们可以直接调用并显示在自己的网站上,下面我来给大家分享几段调用天气预报信息的php实例程序吧.

js调用天气预报方法,中国气象台,代码如下:

<iframe src="http://m.weather.com.cn/m/pn12/weather.htm " width="245" height="110"  
     marginwidth="0" marginheight="0" hspace="0" vspace="0" frameborder="0"  
     scrolling="no"></iframe>

上面是使用了框架方法,不好改自己的格式风格,最简单办法,代码如下:

<?php 
    header("content-type:text/html;charset=utf-8"); 
    $weather = file_get_contents("http://www.weather.com.cn/data/sk/101280601.html"); 
    echo $weather;

html代码如下:

<html> 
    <head> 
    <meta http-equiv="Content-Type" content="text/html;charset=gbk" /> 
    <style type="text/css"> 
    .all span {font:bold 30px/50px "宋体";color:red;} 
    </style> 
    <title>天气预报</title> 
    </head> 
    <body> 
    <div class="all"> 
    这里是：<span class="place">城市</span>, 
    气温是<span class="temp">气温</span>， 
    风向：<span class="wind">风向</span>， 
    风力：<span class="windPower">风力</span> 
    </div> 
    <script type="text/javascript" src="http://127.0.0.1/jquery.js"></script> 
    <script type="text/javascript"> 
    $(function () { 
    $.ajax({ 
    //请求的地址 
    url :　"http://127.0.0.1/weather.php", 
    //请求成功后执行的函数 
    success : function (data) { 
    //用eval()解析返回来的数据，将字符串转成JSON格式 
    var oD = eval((+data+)); 
    //用jquery-1.8.2获取元素 
    var $place = $(".place"), 
    $temp = $(".temp"), 
    $wind = $(".wind"), 
    $windPower = $(".windPower"); 
    //将返回来的数据放到相应的位置 
    $place.html(oD["weatherinfo"]["city"]); 
    $temp.html(oD["weatherinfo"]["temp"] + "&deg;"); 
    $wind.html(oD["weatherinfo"]["WD"]); 
    $windPower.html(oD["weatherinfo"]["WS"]); 
    } 
    }); 
    }) 
    </script> 
    </body> 
    </html>

上面是指定城市了,我们可以在自己网站选择城市,例子代码如下:

<?php 
    /** 
    * php 天气预报代码

    */
        if(!isset($_GET[&#39;q&#39;])){ 
            //根据IP查询所在地 
            $p = file_get_contents("http://www.jbxue.com/ip/?q={$_SERVER[&#39;HTTP_X_FORWARDED_FOR&#39;]}"); 
        } 
        else{ 
            $p = $_GET[&#39;q&#39;]; 
        } 
        $k = 0; 
        $encoding = mb_detect_encoding()($p); 
        if($encoding != "UTF-8"){ 
            $p = mb_convert_encoding($p,"utf-8","gbk"); 
        } 
        $p_arr = array( 
           "01" => "北京", 
          "02" => "上海", 
          "03" => "天津",

        ); 
      
        function find(&$item,$key,$data){

            if(preg_match("/$item/u",$data)){ 
               $k = $key; 
            } 
        } 
      
        function get_data_arr($key){ 
            if(!file_exists("./data/city{$key}.xml")){ 
                $c =file_get_contents( "http://m.weather.com.cn/data5/city{$key}.xml" );   
                file_put_contents("./data/city{$key}.xml",$c); 
            } 
            else{ 
                $c = file_get_contents("./data/city{$key}.xml"); 
            } 
           $arr = explode(",",$c); 
           foreach($arr as $v){ 
               $data = explode("|",$v); 
               $ret[$data[0]] = $data[1]; 
           } 
           return $ret; 
        } 
      
        array_walk($p_arr,&#39;find&#39;,$p); 
        array_walk(get_data_arr($k),&#39;find&#39;,$p); 
        array_walk(get_data_arr($k),&#39;find&#39;,$p); 
        $ccode = get_data_arr($k); 
        echo file_get_contents("http://m.weather.com.cn/data/{$ccode[$k]}.html");
