With the development of the gaming industry, more and more gamers are purchasing games through the Steam platform. As the world's largest PC game distribution platform, Steam provides a wealth of game and community features, attracting a large number of game enthusiasts from around the world. If you are a Steam game enthusiast or a developer who wants to know Steam game information, then this article will introduce how to use PHP language to crawl Steam game information.
1. Understand the Steam API
Steam provides an official API (Application Program Interface, application programming interface). If you are a developer, you can use the official API to obtain game information. However, using the official API requires authentication first, and the official API has many restrictions. For example, obtaining game prices, ratings, recommendations and other information requires users to log in to Steam. Therefore, this article will introduce how to use PHP to crawl web data of Steam game information.
2. Obtain the source code of the Steam game page
Before using PHP to crawl Steam game information, we need to first understand how to obtain the source code of the Steam game page. Open any Steam game details page, open the developer tools in the browser, switch to the "Network" tab, set the request type to "all", and refresh the page. You will see all the request records, and there is one called "store.steampowered.com", which is the request we need.
Move the cursor below the request and find the "Request URL" under the "Headers" tab on the right. This URL is the complete address of the game details page. Copy the address and add it to the PHP code Use the file_get_contents()
function to obtain the source code of the page.
3. Parse the Steam game page source code
The next step in crawling Steam game information is to parse the Steam game page source code. We can parse HTML documents using DOMDocument and DOMXPath classes in PHP. First, we need to pass the downloaded page source code to the loadHTML()
method of the DOMDocument class to create a DOM object, and then query the elements through the query()
method of the DOMXPath class.
The following is a sample code that can parse the name and release date of a Steam game:
$url = "https://store.steampowered.com/app/105600/"; $html = file_get_contents($url); $doc = new DOMDocument(); $doc->loadHTML($html); $xpath = new DOMXPath($doc); $name = $xpath->query('//div[@class="apphub_AppName"]')->item(0)->nodeValue; $date = $xpath->query('//div[@class="date"]')->item(0)->nodeValue; echo "游戏名字:".$name." "; echo "发布日期:".$date." ";
In the above code, we use the XPath query language to query the elements in the Steam game page. Among them, the "//@class=" parameter points to the class name that needs to be queried, the item()
method is used to get the first matching element, and the nodeValue
attribute is used to get the element text content.
4. Crawling more information about Steam games
With the foundation of the previous steps, you can now use the same method to obtain other information about Steam games. The following are some common Steam game information query Xpaths:
- Game price:
$price = $xpath->query('//div[@class="game_purchase_price"]')->item(0)->nodeValue;
- Game rating:
$score = $xpath->query('//div[@class="user_reviews_summary_row"]')->item(0)->getAttribute("data-tooltip-text");
- Game developers and publishers:
$developer = $xpath->query('//div[@id="developers_list"]//a')->item(0)->nodeValue; $publisher = $xpath->query('//div[@id="publishers_list"]//a')->item(0)->nodeValue;
- Recommended game configuration:
$config = $xpath->query('//div[@class="sysreq_contents"]')->item(0)->nodeValue;
In actual use, you can customize the query according to your needs Elements. However, please note that the HTML structure of the Steam website may change, so please check whether your code is running properly. If the structure of the web page changes, you need to update your query method.
5. Submit Steam game information
After completing the crawling of Steam game information, we can submit this information to your database or other data storage. In practice, you may encounter some anti-crawler mechanisms, such as limiting IP addresses, verification codes, etc., so when writing PHP code, please pay attention to abide by Steam's terms for crawlers and use data scraping methods reasonably.
Conclusion
This article introduces the basic method of how to use PHP language to crawl Steam game information. By using technologies such as DOMDocument and DOMXPath, we can extract useful information from Steam game pages, such as game name, publisher, price, ratings, and recommended configurations. I hope this article can be helpful to crawler enthusiasts, Steam game developers, and Steam players.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.

Key players in HTTP cache headers include Cache-Control, ETag, and Last-Modified. 1.Cache-Control is used to control caching policies. Example: Cache-Control:max-age=3600,public. 2. ETag verifies resource changes through unique identifiers, example: ETag: "686897696a7c876b7e". 3.Last-Modified indicates the resource's last modification time, example: Last-Modified:Wed,21Oct201507:28:00GMT.

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.
