phpsocket客户端以及服务器例子

一个菜鸟朋友,突然问了我这个问题...现在稍稍有点时间,就写了一个简单的例子给他,顺便贴上来

服务器端:

<?php /** * @author 邹颢	[email&#160;protected] */class SocketServer{	private $_port=&#39;9000&#39;;	private $_address=&#39;127.0.0.1&#39;;	private $_client_socket_list=array();	public function __set($name,$val){		$this->$name=$val;	}	private function _showError($error){		exit($error);	}	/**	 * 开始进行socket服务器端监听端口	 */	public function start(){		// 创建端口		if (($sock = socket_create ( AF_INET, SOCK_STREAM, SOL_TCP )) === false) {			$this->_showError("socket_create() failed :reason:" . socket_strerror ( socket_last_error () ));		}		// 绑定		if (socket_bind ( $sock, $this->_address, $this->_port ) === false) {			$this->_showError("socket_bind() failed :reason:" . socket_strerror ( socket_last_error ( $sock ) ));		}		// 监听		if (socket_listen ( $sock, 5 ) === false) {			$this->_showError("socket_bind() failed :reason:" . socket_strerror ( socket_last_error ( $sock ) ) );		}		do {			//当有一个客户端连接的时候			if ($client_socket=socket_accept ( $sock )) {				$count = count ( $this->_client_socket_list ) + 1;				//把新来的用户加入 客户端数组里				$this->_client_socket_list[]=$client_socket;				echo "new connection:\r\n";//服务器端输出当前正在连接的客户端数量				echo "current connection:{$count}\r\n";				//接受客户端传过来的字符串				$msg=$this->read($client_socket);				echo "client:{$msg}\r\n";				//服务器向客户端传值				$my_msg="I am fine,think you\r\n";				$this->send($client_socket,$my_msg);			}			/**			 * 这段代码给你参考,用来判断是否有客户端主动失去连接			else{				foreach ( $this->_client_socket_list as $socket ) {					$len = socket_recv ($socket, $buffer, 2048, 0 ); // 接受一下客户端信息,如果为0代表断开连接					if ($len start();//开始监听

客户端:

<?php /** * @author 邹颢	[email&#160;protected] */class SocketServer{	private $_port=&#39;9000&#39;;	private $_address=&#39;127.0.0.1&#39;;	private $_client_socket_list=array();	public function __set($name,$val){		$this->$name=$val;	}	private function _showError($error){		exit($error);	}	/**	 * 开始进行socket服务器端监听端口	 */	public function start(){		// 创建端口		if (($sock = socket_create ( AF_INET, SOCK_STREAM, SOL_TCP )) === false) {			$this->_showError("socket_create() failed :reason:" . socket_strerror ( socket_last_error () ));		}		// 绑定		if (socket_bind ( $sock, $this->_address, $this->_port ) === false) {			$this->_showError("socket_bind() failed :reason:" . socket_strerror ( socket_last_error ( $sock ) ));		}		// 监听		if (socket_listen ( $sock, 5 ) === false) {			$this->_showError("socket_bind() failed :reason:" . socket_strerror ( socket_last_error ( $sock ) ) );		}		do {			//当有一个客户端连接的时候			if ($client_socket=socket_accept ( $sock )) {				$count = count ( $this->_client_socket_list ) + 1;				//把新来的用户加入 客户端数组里				$this->_client_socket_list[]=$client_socket;				echo "new connection:\r\n";//服务器端输出当前正在连接的客户端数量				echo "current connection:{$count}\r\n";				//接受客户端传过来的字符串				$msg=$this->read($client_socket);				echo "client:{$msg}\r\n";				//服务器向客户端传值				$my_msg="I am fine,think you\r\n";				$this->send($client_socket,$my_msg);			}			/**			 * 这段代码给你参考,用来判断是否有客户端主动失去连接			else{				foreach ( $this->_client_socket_list as $socket ) {					$len = socket_recv ($socket, $buffer, 2048, 0 ); // 接受一下客户端信息,如果为0代表断开连接					if ($len start();//开始监听

注意事项:服务器端请用CLI模式运行,cgi模式会超时,新手常喜欢犯的错误.什么是CLI模式,简单的说就是用命令行去执行,而不要用游览器打开,否则会超时的

Explain how load balancing affects session management and how to address it.Explain how load balancing affects session management and how to address it.Apr 29, 2025 am 12:42 AM

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Are there any alternatives to PHP sessions?Are there any alternatives to PHP sessions?Apr 29, 2025 am 12:36 AM

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

mPDF

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),

SecLists

SecLists

SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
