How Amazon ASIN Grabber with Simple Html DOM work ?

You must include simple_html_dom.php on the first.

include "simple_html_dom.php";

1	include "simple_html_dom.php";

Scrap HTML element with

$html = file_get_html('<span style="color: #ff0000;">http://www.amazon.com/s/ref=nb_sb_noss_2/176-0876229-3718769?url=search-alias%3Daps&amp;field-keywords=iphone</span>');

1	$html = file_get_html('<span style="color: #ff0000;">http://www.amazon.com/s/ref=nb_sb_noss_2/176-0876229-3718769?url=search-alias%3Daps&field-keywords=iphone</span>');

Next, you must examine the pattern of ASIN code layout on the amazon html element. in example,

We will grab iphone product in amazon. We get url ” http://www.amazon.com/s/ref=nb_sb_noss_2/176-0876229-3718769?url=search-alias%3Daps&field-keywords=iphone ” open with your browser , ( in this case i use chrome browser ). And then right click and choose view page source . Examine the line of code until you find the same pattern and sequence as follows

&lt;h3 class="newaps"&gt;
 &lt;span style="color: rgb(255, 0, 0);"&gt;&lt;a href="http://www.amazon.com/Apple-iPhone-16GB-Black-Verizon/dp/B004ZLV5UE/ref=sr_1_1?ie=UTF8&amp;amp;qid=1406514795&amp;amp;sr=8-1&amp;amp;keywords=iphone"&gt;&lt;/span&gt;
&lt;span style="color: rgb(255, 0, 0);"&gt;<span style="color: #ff00ff;">&lt;span class="lrg bold"&gt;</span>Apple iPhone 4 16GB (Black) - CDMA Verizon&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;
&lt;span class="med reg"&gt;by Apple (Sep 3, 2011)&lt;/span&gt;
 &lt;/h3&gt;&lt;ul class="rsltL"&gt;
...........
&lt;span style="color: #ff0000;"&gt; &lt;a href="http://www.amazon.com/Apple-iPhone-8GB-White-Verizon/dp/B0074R1IP8/ref=sr_1_3?ie=UTF8&amp;amp;qid=1406514795&amp;amp;sr=8-3&amp;amp;keywords=iphone"&gt;&lt;/span&gt;
&lt;span style="color: #ff0000;"&gt;<span style="color: #ff00ff;">&lt;span class="lrg bold"&gt;</span>Apple iPhone 4 8GB (White) - Verizon&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;

Apple iPhone 4 16GB (Black) - CDMA Verizon</a>

by Apple (Sep 3, 2011)

</h3><ul class="rsltL">

...........

Apple iPhone 4 8GB (White) - Verizon</a>

Find a href element contains , with that code we will get url and the title. Use this script to grab that patern.

 </span>

foreach($html->find('a') as $element)
{
$asin='';
$title='';
foreach ($element->find('span') as $node1)
{
if ($node1->class=='lrg bold')
{
foreach ($node1->find('text') as $node)
{
if ($node->parent() === $node1 && strlen($t = trim($node->plaintext)))
{
$url = $element->href;
$hasil=explode("/",$url);
if (count($hasil)>=5)
{
if ($hasil[4]=='dp')
{
$asin=$hasil[5];
}
}
$title = $t ;
echo '<tr><td align="center">'.$no.'</td><td>'.$asin.'</td><td>'.$title.'</td></tr>';
$no++;
}
}
}
}
}

<span style="color: #000000; font-family: inherit; font-size: 1rem; line-height: inherit;">

foreach($html->find('a') as $element)

{

$asin='';

$title='';

foreach ($element->find('span') as $node1)

{

if ($node1->class=='lrg bold')

{

foreach ($node1->find('text') as $node)

{

if ($node->parent() === $node1 && strlen($t = trim($node->plaintext)))

{

$url = $element->href;

$hasil=explode("/",$url);

if (count($hasil)>=5)

{

if ($hasil[4]=='dp')

{

$asin=$hasil[5];

}

$title = $t ;

echo '<tr><td align="center">'.$no.'</td><td>'.$asin.'</td><td>'.$title.'</td></tr>';

$no++;

}

  I think amazon change the css, try this code
  include “simple_html_dom.php”;
  $html = file_get_html(‘http://www.amazon.com/s/ref=nb_sb_noss_2/176-0876229-3718769?url=search-alias%3Daps&field-keywords=iphone’);
  foreach ($html->find(‘li[class=s-result-item]’) as $node1)
  {
  foreach($node1->find(‘a’) as $linku)
  {
  $url=$linku->href;
  $hasil=explode(“/”,$url);
  if (count($hasil)>=5)
  {
  if ($hasil[4]==’dp’)
  {
  echo $hasil[5].’
  ‘;
  }
  }
  }
  }
  🙂

    Is the above code using : span , there is a change or not used ?
    - Sigit Prasetya Nugroho November 14, 2014 at 1:17 am
      not used…the basic using simple_html_dom is you must be careful in looking for html attributes (with right click and view pagesource).
      change the code with new example code in the comment.
      If you have difficulty to use simple_html_dom, please try my tutorial grab asin using curl, its still working
