Question

我正在努力抓www.weather.bm。我想要所有10个雷达图像，但我只能得到一个（图像定期更新）并且它不是绝对的图像网址。我希望我可以将图像用作链接的图像幻灯片，但不知道如何。另外，如何删除images/Radarlegend.png？我只需要雷达图像。

这是我的代码：

include('simple_html_dom.php');
$html = file_get_html('http://www.weather.bm/radarMobile.asp');
foreach($html->find('img') as $element) 
echo $element->src . '<br>'

我的输出是：

<div id="main">
images/Radar/CurrentRadarAnimation_100km_sri/100km_sri-radar-2011-01-04-1556.jpg<br>images/Radarlegend.png<br></div>
</div>

Answer 1

    $localOffset = "+2 Hours"; //change this to your local offset from the image times you need. for me (CST) it's 2 hours.....
    $start=  strtotime("-90 Minutes " . $localOffset); // go back 90 minutes (The limit of the available images)
    $start=($start-($start % (600))+(60*6)); //go to the next earlier 6 minute mark (all images appear to be at the 6 minute mark))appear to be at the 6 minute mark))
    for($x=1;$x<=9;$x++){
        $DateTime = date("Y-m-d-Hi", $start); // set the image time we want.
        $fName = ("http://www.weather.bm/images/Radar/CurrentRadarAnimation_100km_sri/100km_sri-radar-$DateTime.jpg"); // set the filename
        echo" $min <img src='$fName' alt='$fName'/><br/>"; // echo (or add to a stack or variable...) your image node
         $start+=(600);//add 10 minutes
    }

JavaScript中有所有十个图像的列表（格式更改为我的）：

radarFileNames = new Array(
    'images/Radar/CurrentRadarAnimation_100km_sri/100km_sri-radar-2011-01-04-1446.jpg', 
    'images/Radar/CurrentRadarAnimation_100km_sri/100km_sri-radar-2011-01-04-1456.jpg', 
    'images/Radar/CurrentRadarAnimation_100km_sri/100km_sri-radar-2011-01-04-1506.jpg', 
    'images/Radar/CurrentRadarAnimation_100km_sri/100km_sri-radar-2011-01-04-1516.jpg', 
    'images/Radar/CurrentRadarAnimation_100km_sri/100km_sri-radar-2011-01-04-1526.jpg', 
    'images/Radar/CurrentRadarAnimation_100km_sri/100km_sri-radar-2011-01-04-1536.jpg', 
    'images/Radar/CurrentRadarAnimation_100km_sri/100km_sri-radar-2011-01-04-1546.jpg', 
    'images/Radar/CurrentRadarAnimation_100km_sri/100km_sri-radar-2011-01-04-1556.jpg', 
    'images/Radar/CurrentRadarAnimation_100km_sri/100km_sri-radar-2011-01-04-1606.jpg');

对包含radarFileNames = new Array的行进行简单搜索将返回此行。然后，您可以使用两个preg_split()s提取网址：首先在\(|\)上，然后在', '上拆分第二个标记。最后，将http://www.weather.bm/添加到网址。
