[英]How do I wait for my script to load the page with PHP Simple HTML DOM Parser?
I'm making a call to a website where they have a javascript loading code.我正在调用一个网站,在那里他们有一个 javascript 加载代码。 When I launch the script I only collect the data that is already loaded but it doesn't wait for it to load the whole page.
当我启动脚本时,我只收集已经加载的数据,但不会等待它加载整个页面。
I try to collect the data shown in some div to make a statistic in my backend from the web of trivago, which has a loader in the.我尝试收集某个 div 中显示的数据,以便在我的后端从 trivago 的 web 中进行统计,该 web 中有一个加载器。 To do this I launch the following code:
为此,我启动了以下代码:
include_once('simple_html_dom.php');
function getHTML($url,$timeout){
$ch = curl_init($url); // initialize curl with given url
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER["HTTPS_USER_AGENT"]); // set
useragent
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // write the response to a variable
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // follow redirects if any
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); // max. seconds to execute
curl_setopt($ch, CURLOPT_FAILONERROR, 1); // stop when it encounters an error
return @curl_exec($ch);
}
$html = file_get_html("https://www.trivago.es/?aDateRange%5Barr%5D=13-04-2019&aDateRange%5Bdep%5D=14-04-2019&iPathId=82650&iGeoDistanceItem=0&aCategoryRange=0%2C1%2C2%2C3%2C4%2C5&aOverallLiking=1%2C2%2C3%2C4%2C5&sOrderBy=relevance%20desc&iRoomType=7&cpt=8265003&iViewType=0&bIsSeoPage=false&bIsSitemap=false&");
I try to collect the data with the find() function:我尝试使用 find() 函数收集数据:
foreach($html->find("div.item__flex-column") as $seccion) {
echo "<tr>";
echo "<td>";
echo $seccion->find("h3",0)->plaintext;
echo "</td>";
echo "<td>";
echo $seccion->find("p.details__paragraph",0)->plaintext;
echo "</td>";
echo "<td>";
echo $seccion->find("strong.item__best-price",0)->plaintext;
echo "</td>";
echo "<td style='text-decoration:line-through;'>";
echo $seccion->find($fmp,0)->plaintext;
echo "</td>";
echo "</tr>";
}
And the mistake I get:我得到的错误是:
Fatal error: Uncaught Error: Call to a member function find() on string
致命错误:未捕获的错误:在字符串上调用成员函数 find()
Is there any way to stop the PHP program until it loads the whole page?有没有办法停止 PHP 程序直到它加载整个页面?
尝试
echo $seccion->find("h3")[0]->plaintext;
