This article mainly introduces PHP to implement the collection of China proxy server network. Interested friends can refer to it. I hope it will be helpful to everyone.
The example in this article describes the method of collecting China's proxy server network in PHP. The details are as follows:
<?php /** * 采集中国代理服务器网 最新列表 */ class proxy { /* 需采集列表 */ public $list; /* 代理列表 保存路径 */ public $save_path = 'proxy.txt'; /* 获取采集列表 */ function get_list($page) { $url = 'http://www.cnproxy.com/proxy(*).html'; // 处理列表 $this->list = preg_replace('/\(\*\)/', $page, $url); return $this->list; } /* 采集代理内容 */ function get($page) { $this->get_list($page); $file = stripslashes(file_get_contents($this->list)); $zz = '/<tr><td>([0-9\.]+)<SCRIPT type=text\/javascript>document\.write\(":"([\+a-z]+)\)<\/SCRIPT><\/td><td>[\w]+<\/td><td>[\w\,]+<\/td>/is'; preg_match_all($zz, $file, $temp); unset($temp[0]); $th = array('z', 'm', 'k', 'l', 'd', 'x', 'i', 'w', 'q', 'b'); $th2 = array(3, 4, 2, 9, 0, 5, 7, 6, 8, 1); foreach ($temp[2] as $k=>$v) { $v = preg_replace("/[\+]+/", '', $v); $s = str_replace($th, $th2, $v); $re .= $temp[1][$k] . ':' . $s . "\r\n"; } $this->save($re); return true; } /* 保存 */ function save($re) { return file_put_contents($this->save_path, $re, FILE_APPEND); } /* 读取 */ function read() { return file_get_contents($this->save_path); } } // 初始化采集类 $p = new proxy; $start = 1; $end = 10; // 控制 if($_GET['a'] == 'start') { echo '正在发送采集请求'; echo '<meta http-equiv="Refresh" content="3;URL=?p=1">'; } elseif(isset($_GET['p'])) { $i = $_GET['p']++; if($i >= $end+1) { exit('<meta http-equiv="Refresh" content="0;URL=?a=end">'); } else { echo '正在请求列表 '. $i .' > '. $end; if($p->get($i)) { echo '<meta http-equiv="Refresh" content="3;URL=?p='.$_GET['p']++.'">'; } } } elseif($_GET['a'] == 'end') { echo '采集完毕'; } else { echo '<form> <input type="hidden" name="a" value="start" /> <input type="submit" value="开始采集" /> </form>'; } ?>

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
