谁有 15天天气预报 源码 最好是PHP的 或者API接口
你好，目前相关气象部门给出的都是七天天气预报，而且前三天是基本预报，后四天是参考天气，没有15天的毕竟天有不测风云，
php怎么抓取天气预报？
可以借由php的api或者preg_match_all偷偷撷取去达成目的
这里给你一段我给台湾朋友有一段源码
?php
header(\"Content-Type: text/html; charset=utf-8\");
function getWeather($city){
$toURL = \"
$city.htm\";
$post = array();
$ch = curl_init();
$options = array(
CURLOPT_REFERER='',
CURLOPT_URL=$toURL,
CURLOPT_VERBOSE=0,
CURLOPT_RETURNTRANSFER=true,
CURLOPT_USERAGENT=\"Mozilla/4.0 (compatible;)\",
CURLOPT_POST=true,
CURLOPT_POSTFIELDS=http_build_query($post),
);
curl_setopt_array($ch, $options);
$result = curl_exec($ch);
curl_close($ch);
//连接中央气象局
echo 'pre';
preg_match_all('/table class=\"FcstBoxTable01\" [^]*[^]*(.*)\/div/si',$result, $matches, PREG_SET_ORDER);
preg_match_all('/td nowrap=\"nowrap\" [^]*[^]*(.*)\/td/si',$matches[0][1], $m1, PREG_SET_ORDER);
$m2 = explode('/td',$m1[0][1]);
// print_r($m2);//取得每日资料m2[0~6]
$weather = array();
for($i=0;$i=6;$i++){
preg_match_all('/src=[^]*[^](.*)/si',$m2[$i], $m5, PREG_SET_ORDER);//取得天气图档
$m6 = explode('\"',$m5[0][0]);
$wi='
($m6[1],'\.\./\.\./');
$wtitle = $m6[3];
print_r($wtitle);
$weather[$i]['date'] = date(\"m-d\", mktime(0, 0, 0, date(\"m\"), date(\"d\")+$i,date(\"Y\")));
$weather[$i]['temperature'] = trim(strip_tags($m2[$i]));
$weather[$i]['title'] = $wtitle;
$weather[$i]['img'] = $wi;
}
return($weather);
}
$weather=getWeather(\"Taipei_City\") ;
print_r($weather);
// header(\"Location:loc.php\");
?
首先
$toURL = \"\";
这里是读取资料的网址
上面的是台湾中央气象局
preg_match_all('/table class=\"FcstBoxTable01\" [^]*[^]*(.*)\/div/si',$result, $matches, PREG_SET_ORDER);
preg_match_all('/td nowrap=\"nowrap\" [^]*[^]*(.*)\/td/si',$matches[0][1], $m1, PREG_SET_ORDER);
这里是截取台湾中央气象局网页信息table class=\"FcstBoxTable01\" [^]*[^]*(.*)\/div的资料以及td nowrap=\"nowrap\" [^]*[^]*(.*)\/td的资料分别是1天跟1周
$m2 = explode('/td',$m1[0][1]);
// print_r($m2);//取得每日资料m2[0~6]
这里是取得每日的资料
preg_match_all('/src=[^]*[^](.*)/si',$m2[$i], $m5, PREG_SET_ORDER);//取得天气图档
这里是取得天气的图档
$m6 = explode('\"',$m5[0][0]);
$wi='
($m6[1],'\.\./\.\./');
$wtitle = $m6[3];
print_r($wtitle);
$weather[$i]['date'] = date(\"m-d\", mktime(0, 0, 0, date(\"m\"), date(\"d\")+$i,date(\"Y\")));
$weather[$i]['temperature'] = trim(strip_tags($m2[$i]));
$weather[$i]['title'] = $wtitle;
$weather[$i]['img'] = $wi;
这里是返回的网址，日期，标题，图档等等的资料
$weather=getWeather(\"Taipei_City\") ;
print_r($weather);
然后这里是显示出地区的一周天气预报
结论:就是如果你想从网站上面截取天气预报
在php可以是用preg_match_all（网页的表格table，表格的列数tr，表格的栏位td，或者更加广泛的标签div等等获取）
php获取天气预报的代码
?php
$URLStyle = "";
$chinaURL = sprintf($URLStyle, "china");
$chinaStr = file_get_contents($chinaURL);
$chinaObj = simplexml_load_string($chinaStr);
$chinaObjLen = count($chinaObj-city);
echo "chinaObjLen = ".$chinaObjLen."\n";
for ($i=0;$i$chinaObjLen;$i++){
//遍历省一级节点，共37个
$level1 = $chinaObj-city[$i]["pyName"];
$shengjiURL = sprintf($URLStyle, $level1);
$shengjiStr = file_get_contents($shengjiURL);
//echo $shengjiStr;
$shengjiObj = simplexml_load_string($shengjiStr);
$shengjiObjLen = count($shengjiObj-city);
// echo $chinaObj-city[$i]["quName"];
// echo " ".$shengjiObjLen."\n";
for ($j=0;$j$shengjiObjLen;$j++){
//遍历市一级节点
$level2 = $shengjiObj-city[$j]["pyName"];
$shijiURL = sprintf($URLStyle, $level2);
$shijiStr = file_get_contents($shijiURL);
//echo $shijiStr;
$shijiObj = simplexml_load_string($shijiStr);
//直辖市和海南、台湾、钓鱼岛等没有县级节点
if(!$shijiObj){
echo "WARNNING: not exsit next level node. - ".$level1."-".$shijiURL."\n";
echo ' "'.$shengjiObj-city[$j]["cityname"].'" = ';
echo $shengjiObj-city[$j]["url"].",\n";
continue;
}
$shijiObjLen = count($shijiObj-city);
//echo $shengjiObj-city[$j]["cityname"]." ";
//echo $shijiObjLen."\n";
for ($k=0;$k$shijiObjLen;$k++){
//遍历县一级节点
$xianji_code = $shijiObj-city[$k]["url"];
echo ' "'.$shijiObj-city[$k]["cityname"].'" = ';
echo $shijiObj-city[$k]["url"].",\n";
//echo $xianji_code."\n";
}
}
}
//print_r($chinaObj);
?
通过XML接口根节点递归获得全国几千个县以上城市cide code的代码
