说到采集,无非就是远程获取信息->提取所需内容->分类存储->读取->展示
也算是简单"小偷程序"的加强版吧
下面是对应核心代码(别拿去做坏事哦^_^)
所要采集的内容是某游戏网站上的公告,如下图:
可先利用file_get_contents和简单正则获取基本页面信息
整理下基本信息,采集入库:
<?php include_once("conn.php"); if($_GET['id']<=8&&$_GET['id']){ $id=$_GET['id']; $conn=file_get_contents("http://www.93moli.com/news_list_4_$id.html");//获取页面内容 $pattern="/<li><a title=\"(.*)\" target=\"_blank\" href=\"(.*)\">/iUs";//正则 preg_match_all($pattern, $conn, $arr);//匹配内容到arr数组 //print_r($arr);die; foreach ($arr[1] as $key => $value) {//二维数组[2]对应id和[1]刚好一样,利用起key $url="http://www.93moli.com/".$arr[2][$key]; $sql="insert into list(title,url) value ('$value', '$url')"; mysql_query($sql); //echo "<a href='content.php?url=http://www.93moli.com/$url'>$value</a>"."<br/>"; } $id++; echo "正在采集URL数据列表$id...请稍后..."; echo "<script>window.location='list.php?id=$id'</script>"; }else{ echo "采集数据结束。"; } ?>
conn.php是数据库连接文件
list.php是本页面
由于要采集的数据是分页显示的,且页面地址是规律递增,所以我用了js跳转代码,利用id传值控制采集的页数,也避免了for循环数目过大。
轻轻松松数据入库,下篇文章写关于具体url采集信息的过程。

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.
