[Here is my code]
<?php
require "simple_html_dom.php";
$html=file_get_html("http://zuhaus.vn/zu-design-pc150502.html?page=1");
$ds=$html->find("ul.products li");
foreach ($ds as $sp) {
# code...
$price=$sp->find("span.price span",0);
echo $price;
$name=$sp->find("h3 a",1)->innertext;
echo $name;
}
?>
I have tried a lot of test case but it wont work :"<
Thanks you
P/s I used library simple_html_dom

Answer 1

If you want to get the contents of a tag and included in h3 then you have a syntax error in the line
$name = $sp->find("h3 a", 1)->innertext;
I suggest checking the syntax for the following
$name = $sp->find('h3', 1)->find('a', 1)->innertext;

Answer 2

the problem is with your selector, i changed the selector for the product name, and it just worked, also use curl to improve the fast of crawling
<?php
require "simple_html_dom.php";
$ch = curl_init("http://zuhaus.vn/zu-design-pc150502.html?page=1");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$curl_scraped_page = curl_exec($ch);
$html = new simple_html_dom();
$html->load($curl_scraped_page);
$ds=$html->find("ul.products li");
foreach ($ds as $sp) {
# code...
$price=$sp->find("span.price span",0);
echo $price;
$name=$sp->find("a",3)->innertext; // this is where the problem on your code
echo $name;
echo "</br>";
}
?>
