This article provides a detailed introduction to the FTP class operated by PHP. PHP implements FTP upload, FTP download, FTP move, FTP creation, etc. for your reference. The specific content is as follows
1. Use PHP to operate FTP-usage
<?php // 联接FTP服务器 $conn = ftp_connect(ftp.server.com); // 使用username和password登录 ftp_login($conn, “john”, “doe”); // 获取远端系统类型 ftp_systype($conn); // 列示文件 $filelist = ftp_nlist($conn, “.”); // 下载文件 ftp_get($conn, “data.zip”, “data.zip”, FTP_BINARY); // 关闭联接 ftp_quit($conn); //初结化一个FTP联接,PHP提供了ftp_connect()这个函数,它使用主机名称和端口作为参数。在上面的例子里,主机名字为 “ftp.server.com”;如果端口没指定,PHP将会使用“21”作为缺省端口来建立联接。 //联接成功后ftp_connect()传回一个handle句柄;这个handle将被以后使用的FTP函数使用。 $conn = ftp_connect(ftp.server.com); //一旦建立联接,使用ftp_login()发送一个用户名称和用户密码。你可以看到,这个函数ftp_login()使用了 ftp_connect()函数传来的handle,以确定用户名和密码能被提交到正确的服务器。 ftp_login($conn, “john”, “doe”); // close connection ftp_quit($conn); //登录了FTP服务器,PHP提供了一些函数,它们能获取一些关于系统和文件以及目录的信息。 ftp_pwd() //获取当前所在的目录 $here = ftp_pwd($conn); //获取服务器端系统信息ftp_systype() $server_os = ftp_systype($conn); //被动模式(PASV)的开关,打开或关闭PASV(1表示开) ftp_pasv($conn, 1); //进入目录中用ftp_chdir()函数,它接受一个目录名作为参数。 ftp_chdir($conn, “public_html”); //回到所在的目录父目录用ftp_cdup()实现 ftp_cdup($conn); //建立或移动一个目录,这要使用ftp_mkdir()和ftp_rmdir()函数;注意:ftp_mkdir()建立成功的话,就会返回新建立的目录名。 ftp_mkdir($conn, “test”); ftp_rmdir($conn, “test”); //上传文件,ftp_put()函数能很好的胜任,它需要你指定一个本地文件名,上传后的文件名以及传输的类型。比方说:如果你想上传 “abc.txt”这个文件,上传后命名为“xyz.txt”,命令应该是这样: ftp_put($conn, “xyz.txt”, “abc.txt”, FTP_ASCII); //下载文件:PHP所提供的函数是ftp_get(),它也需要一个服务器上文件名,下载后的文件名,以及传输类型作为参数,例如:服务器端文件为his.zip,你想下载至本地机,并命名为hers.zip,命令如下: ftp_get($conn, “hers.zip”, “his.zip”, FTP_BINARY); //PHP提供两种方法:一种是简单列示文件名和目录,另一种就是详细的列示文件的大小,权限,创立时间等信息。 //第一种使用ftp_nlist()函数,第二种用ftp_rawlist().两种函数都需要一个目录名做为参数,都返回目录列做为一个数组,数组的每一个元素相当于列表的一行。 $filelist = ftp_nlist($conn, “.”); //函数ftp_size(),它返回你所指定的文件的大小,使用BITES作为单位。要指出的是,如果它返回的是 “-1”的话,意味着这是一个目录 $filelist = ftp_size($conn, “data.zip”); ?>
2. FTP upload class (ftp.php)
<?php /******************************************** * MODULE:FTP类 *******************************************/ 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 ftp('222.13.67.42',21,'hlj','123456'); // 打开FTP连接 $ftp->up_file('aa.wav','test/13548957217/bb.wav'); // 上传文件 //$ftp->move_file('aaa/aaa.php','aaa.php'); // 移动文件 //$ftp->copy_file('aaa.php','aaa/aaa.php'); // 复制文件 //$ftp->del_file('aaa.php'); // 删除文件 $ftp->close(); // 关闭FTP连接 //******************************************************************************/
3. PHP uses FTP function to create a directory
<?php // create directory through FTP connection function FtpMkdir($path, $newDir) { $server='ftp.yourserver.com'; // ftp server $connection = ftp_connect($server); // connection // login to ftp server $user = "me"; $pass = "password"; $result = ftp_login($connection, $user, $pass); // check if connection was made if ((!$connection) || (!$result)) { return false; exit(); } else { ftp_chdir($connection, $path); // go to destination dir if(ftp_mkdir($connection,$newDir)) { // create directory return $newDir; } else { return false; } ftp_close($conn_id); // close connection } } ?>
The above is the entire content of this article, I hope it will be useful to you It will be helpful for everyone to learn PHP programming.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
