php ftp class (upload, download, copy, move, etc.)
I will introduce to you a ftp operation class implemented by PHP code, which can realize file upload and download, copy and move, file deletion, directory creation, etc. Friends in need can refer to it.
1. FTP code <?php /** * 作用:FTP操作类( 拷贝、移动、删除文件/创建目录 ) * 时间:2012/5/9 * 作者:欣然随风 * site:bbs.it-home.org */ class class_ftp { public $off; // 返回操作状态(成功/失败) public $conn_id; // FTP连接 /** * 方法:FTP连接 * @FTP_HOST -- FTP主机 * @FTP_PORT -- 端口 * @FTP_USER -- 用户名 * @FTP_PASS -- 密码 */ function __construct($FTP_HOST,$FTP_PORT,$FTP_USER,$FTP_PASS) { $this->conn_id = @ftp_connect($FTP_HOST,$FTP_PORT) or die("FTP服务器连接失败"); @ftp_login($this->conn_id,$FTP_USER,$FTP_PASS) or die("FTP服务器登陆失败"); @ftp_pasv($this->conn_id,1); // 打开被动模拟 } /** * 方法:上传文件 * @path -- 本地路径 * @newpath -- 上传路径 * @type -- 若目标目录不存在则新建 */ function up_file($path,$newpath,$type=true) { if($type) $this->dir_mkdirs($newpath); $this->off = @ftp_put($this->conn_id,$newpath,$path,FTP_BINARY); if(!$this->off) echo "文件上传失败,请检查权限及路径是否正确!"; } /** * 方法:移动文件 * @path -- 原路径 * @newpath -- 新路径 * @type -- 若目标目录不存在则新建 */ function move_file($path,$newpath,$type=true) { if($type) $this->dir_mkdirs($newpath); $this->off = @ftp_rename($this->conn_id,$path,$newpath); if(!$this->off) echo "文件移动失败,请检查权限及原路径是否正确!"; } /** * 方法:复制文件 * 说明:由于FTP无复制命令,本方法变通操作为:下载后再上传到新的路径 * @path -- 原路径 * @newpath -- 新路径 * @type -- 若目标目录不存在则新建 */ function copy_file($path,$newpath,$type=true) { $downpath = "c:/tmp.dat"; $this->off = @ftp_get($this->conn_id,$downpath,$path,FTP_BINARY);// 下载 if(!$this->off) echo "文件复制失败,请检查权限及原路径是否正确!"; $this->up_file($downpath,$newpath,$type); } /** * 方法:删除文件 * @path -- 路径 */ function del_file($path) { $this->off = @ftp_delete($this->conn_id,$path); if(!$this->off) echo "文件删除失败,请检查权限及路径是否正确!"; } /** * 方法:生成目录 * @path -- 路径 */ function dir_mkdirs($path) { $path_arr = explode('/',$path); // 取目录数组 $file_name = array_pop($path_arr); // 弹出文件名 $path_div = count($path_arr); // 取层数 foreach($path_arr as $val) // 创建目录 { if(@ftp_chdir($this->conn_id,$val) == FALSE) { $tmp = @ftp_mkdir($this->conn_id,$val); if($tmp == FALSE) { echo "目录创建失败,请检查权限及路径是否正确!"; exit; } @ftp_chdir($this->conn_id,$val); } } for($i=1;$i<=$path_div;$i++) // 回退到根 { @ftp_cdup($this->conn_id); } } /** * 方法:关闭FTP连接 */ function close() { @ftp_close($this->conn_id); } }// class class_ftp end /******* 测试 ********** $ftp = new class_ftp('192.168.100.143',21,'user','pwd'); // 打开FTP连接 //$ftp->up_file('aa.txt','a/b/c/cc.txt'); // 上传文件 //$ftp->move_file('a/b/c/cc.txt','a/cc.txt'); // 移动文件 //$ftp->copy_file('a/cc.txt','a/b/dd.txt'); // 复制文件 //$ftp->del_file('a/b/dd.txt'); // 删除文件 $ftp->close(); // 关闭FTP连接 *****************/ ?> Copy after login |

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
