What is a PHP Web Scraper?

What is a PHP Web Scraper?

A PHP website scraper, also known as a PHP parser for HTML, is a web scraper that’s programmed using PHP. One of the oldest and most popular web programming languages, PHP is often used by programmers due to its many advantages, including:

  • PHP parsing HTML is easy to run. Unlike many other languages, you only need to have a machine with PHP installed to run PHP code.
  • It uses simple syntax, making it a great choice for beginners.
  • PHP has been around since 2005, which means there are many resources, frameworks, and tutorials for PHP.
  • It’s great for extracting information from simple pages (i.e., pages that don’t use dynamic content).
  • It can help you store or save the scraped data much easier.

However, there are also some disadvantages to using PHP to build your web scraper, including:

  • It’s difficult to use PHP to scrape dynamic content compared to Javascript or Python.
  • PHP code can be fragile. It can break if the web developer changes the target site’s HTML, leading to data loss.
  • It’s almost impossible to get real-time data with PHP. As such, if you want to build a web scraper to get real-time data, you’ll need to use another programming language.

How to Make a Web Scraper in PHP

How to Make a Web Scraper in PHP

Before you start building a PHP web scraper, make sure you have:

  • Basic knowledge of HTML
  • Basic knowledge of PHP (and OOPS concept)
  • Simple HTML DOM Parser, which is a library made for PHP versions from 5.6+ (This allows access to the target web page’s content easily, through selectors.)
  • PHP5+ or 7+ on your computer

Now, let’s jump into the PHP web scraping tutorial.

Install the latest version of the simple HTML DOM parser.

First, you’ll need to make sure you have the latest version of the simple HTML DOM parser installed. Click here to install the HTL DOM parser.

Once it’s been downloaded, extract or unzip the file and create a new directory. Then, copy and paste the simple_html_dom.php file into the directory. Create a new file called name scraper.php and save it inside this directory.

Get access to all the functions in the library

The next step is to get access to all of the PHP library’s functions. Open the scraper.php file in a text editor. Then, include a reference to the simple HTML DOM parser library at the top of your script.

Decide what you want to scrape

Before we start building the scraper, you need to decide what URL you want to scrape. In this PHP web scraper tutorial, we’ll be scraping user reviews for the TV series “Loki” from The URL of the target web page is

Then, determine what you want to extract (i.e., the titles of the reviews, the star ratings, etc.). We’ll be scraping the titles of reviews and the star ratings for this PHP web scraping tutorial.

Building the scraper

Create a DOM object to store the above URL’s content. Create a variable named HTML and give it the value which returns as the DOM object from the file_get_html_() function:

$html = file_get_html(‘‘, false);

Right-click on a review title and select “inspect” to look at the page’s HTML elements and CSS selectors. Now, look at the Elements tab to identify the HTML elements and CSS selectors that refer to what you want to scrape — which are the titles of the reviews and the star ratings for “Loki” on IMDB.

As you can see in the screenshot, the CSS class selector “review-container” is used for all <div> tags that contain the titles of the reviews and the star ratings.

Continue looking through Elements to spot other relevant class selectors. You’ll find that:

  • “Title” refers to the title of the review
  • “Lpl-ratings-bar” refers to the number of star ratings

Then, use the following code to extract the data you need with the help of each class selector.

$results = array();

if (!empty($html)) {

  $div_class = $title = “”;

  $i = 0;

  foreach ($html->find(“.review-container”) as $div_class) 

      //Extract the review title

      foreach ($div_class->find(“.title”) as $title) {

          $results[$i][‘title’] = $title->plaintext;


      //Extract the number of star ratings

      foreach ($div_class->find(“.ipl-ratings-bar”) as $ratings) {

          $results[$i][‘ratings’] = $ratings->plaintext;

Now, all of the extracted data will be stored in $results. By printing this array, you will get a scraping output you need to convert into an XML element.

You can do this by using the built-in class, SimpleXMLElement, and the following code:

function convertToXML($results, &$xml_user_info){

 foreach($results as $key => $value){


         $subnode = $xml_user_info->addChild($key);

         foreach ($value as $k=>$v) {

             $xml_user_info->addChild(“$k”, $v);






 return $xml_user_info->asXML();

$xml_user_info = new SimpleXMLElement(‘<?xml version=\”1.0\”?><root></root>’);

$xml_content = convertToXML($results,$xml_user_info);

Code by saasindustries on Github via Zenscrape.

Now that the data is stored in $xml_content variable, you need to create an XML file and write the data in the $xml_content variable to that XML file:

$xmlFile = ‘MovieReview.xml’;

$handle = fopen($xmlFile, ‘w’) or die(‘Unable to open the file: ‘.$xmlFile);

if(fwrite($handle, $xml_content)) {

  echo ‘Successfully written to an XML file.’;


  echo ‘Error in file generating’;

Code by saasindustries on Github  via Zenscrape.

And you’re done — all the data you wanted to scrape has been stored in an XML file.

Best Proxies to Use for Web Scraping with PHP

Best Practices for PHP Parser or HTML Scraping

Best Practices for PHP Parser or HTML Scraping

Scraping can be a controversial topic, particularly if you’re using proxies. Here’s how you can avoid trouble and be an ethical scraper:

  1. Respect your target site’s robots.txt file. Play by your target website’s rules. Even if you encounter a rule that seems unfair to you, remember that website owners have the right to limit certain actions.
  2. Treat the target site gently. With a powerful PHP scraper and rotating residential proxies, you may be tempted to scrape as quickly and frequently as possible. However, that could overload the server. Consider putting random delays between requests and use auto-throttling to limit the crawling speed based on how much the target website can take.
