wie man Daten von anderer Web site mit curl in php

Question

zieht, möchte ich Daten von amazon besten Geschäften url.and ziehen, um nur den Produktteil nicht das Gesamte ie zu zeigen. Header und Sidebar und begrenzen auf 8 Produkte. ich bin mit curl und einfachen html dom in php

include_once("php/simple_html_dom.php"); 
//use curl to get html content 
function getHTML($url,$timeout) 
{ 
     $ch = curl_init($url); // initialize curl with given url 
     curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER["HTTP_USER_AGENT"]); // set useragent 
     curl_setopt($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); 
} 
echo $html=getHTML("http://www.amazon.in/gp/goldbox/ref=nav_topnav_deals",10); 

?>

Answer 1

Sie können XPath verwenden. Werfen Sie einen Blick auf this tutorial on scraping the web in PHP. In Ihrem Fall haben Sie hier nicht den gesamten HTML-Code angegeben, aber ich schätze, Sie möchten das erste div aufnehmen.

$document = new DOMDocument; 

libxml_use_internal_errors(true); 

$document->loadHTML($output); 

$xpath = new DOMXPath($document); 

$data = $xpath->query("//div[@id='100_dealView_0']"); 

foreach ($data as $d) { // in case there are multiple (there shouldn't be) 
    echo $d->nodeValue; 
}
