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;

Copy after login

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 
	* by www.phprm.com 
	*/ 
	    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", 
	      "04" => "重庆", 
	      "05" => "黑龙江", 
	      "06" => "吉林", 
	      "07" => "辽宁", 
	      "08" => "内蒙古", 
	      "09" => "河北", 
	      "10" => "山西", 
	      "11" => "陕西", 
	      "12" => "山东", 
	      "13" => "新疆", 
	      "14" => "西藏", 
	      "15" => "青海", 
	      "16" => "甘肃", 
	      "17" => "宁夏", 
	      "18" => "河南", 
	      "19" => "江苏", 
	      "20" => "湖北", 
	      "21" => "浙江", 
	      "22" => "安徽", 
	      "23" => "福建", 
	      "24" => "江西", 
	      "25" => "湖南", 
	      "26" => "贵州", 
	      "27" => "四川", 
	      "28" => "广东", 
	      "29" => "云南", 
	      "30" => "广西", 
	      "31" => "海南", 
	      "32" => "香港", 
	      "33" => "澳门", 
	      "34" => "台湾" 
	    ); 
	 
	    function find(&$item,$key,$data){ 
	        global $k; 
	        if(preg_match("/$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");

还有很多像可以调用更详细的天气信息的我们这里就不介绍了,大家可到天气网站去看他们提供的api接口.
