php采集天气预报2段代码
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"] + "°");
$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['q'])){
//根据IP查询所在地
$p = file_get_contents("http://www.jbxue.com/ip/?q={$_SERVER['HTTP_X_FORWARDED_FOR']}");
}
else{
$p = $_GET['q'];
}
$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,'find',$p);
array_walk(get_data_arr($k),'find',$p);
array_walk(get_data_arr($k),'find',$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.
