The example in this article describes how PHP uses simple_html_dom to parse HTML. I share it with you for your reference. The details are as follows:

I wrote two crawlers today, one using Python and one using PHP. To be honest, both implementation methods are very convenient.

Let’s talk about using the open source class simple_html_dom. Parse HTML code:

1. Download simple_html_dom:

http://sourceforge.net/projects/simplehtmldom/files/

or click here to download from this site.

2. Usage examples:

<&#63;php
// example of how to use basic selector to retrieve HTML contents
include('../simple_html_dom.php');
// get DOM from URL or file
$html = file_get_html('http://www.google.com/');
// find all link
foreach($html->find('a') as $e) 
  echo $e->href . '<br>';
// find all image
foreach($html->find('img') as $e)
  echo $e->src . '<br>';
// find all image with full tag
foreach($html->find('img') as $e)
  echo $e->outertext . '<br>';
// find all div tags with id=gbar
foreach($html->find('div#gbar') as $e)
  echo $e->innertext . '<br>';
// find all span tags with class=gb1
foreach($html->find('span.gb1') as $e)
  echo $e->outertext . '<br>';
// find all td tags with attribite align=center
foreach($html->find('td[align=center]') as $e)
  echo $e->innertext . '<br>';
// extract text from table
echo $html->find('td[align="center"]', 1)->plaintext.'<br><hr>';
// extract text from HTML
echo $html->plaintext;
?>
