PHP的灵活FTP和SSL-FTP客户端。该库提供了一些易于使用的辅助函数来管理远程文件。

此包旨在保持简单和轻量。它仅是PHP的FTP原生API的包装，并提供了一些有用的辅助函数。如果您想自定义一些方法，可以通过继承包中的3个类之一来实现。

安装

• 使用composer: require yeling/php-ftp-client

• 或使用GIT克隆命令: git clone git@github.com:tc_net/php-ftp-client.git

• 或下载库，配置自动加载器或包含php-ftp-client/src/FtpClient目录中的3个文件。

入门

连接到FTP服务器

$ftp = new \FtpClient\FtpClient();
$ftp->connect($host);
$ftp->login($login, $password);

或

通过SSL连接到FTP服务器（在990端口或另一个端口）

$ftp = new \FtpClient\FtpClient();
$ftp->connect($host, true, 990);
$ftp->login($login, $password);

注意：脚本执行结束时（对象被销毁时），连接会隐式关闭。因此，除非您要进行显式重新连接，否则无需调用$ftp->close()。

用法

上传所有文件和所有目录非常简单

// upload with the BINARY mode
$ftp->putAll($source_directory, $target_directory);

// Is equal to
$ftp->putAll($source_directory, $target_directory, FTP_BINARY);

// or upload with the ASCII mode
$ftp->putAll($source_directory, $target_directory, FTP_ASCII);

注意：FTP_ASCII和FTP_BINARY是PHP内部预定义的常量。

获取目录大小

// size of the current directory
$size = $ftp->dirSize();

// size of a given directory
$size = $ftp->dirSize('/path/of/directory');

计算目录中的项目数

// count in the current directory
$total = $ftp->count();

// count in a given directory
$total = $ftp->count('/path/of/directory');

// count only the "files" in the current directory
$total_file = $ftp->count('.', 'file');

// count only the "files" in a given directory
$total_file = $ftp->count('/path/of/directory', 'file');

// count only the "directories" in a given directory
$total_dir = $ftp->count('/path/of/directory', 'directory');

// count only the "symbolic links" in a given directory
$total_link = $ftp->count('/path/of/directory', 'link');

所有文件和目录的详细列表

// scan the current directory and returns the details of each item
$items = $ftp->scanDir();

// scan the current directory (recursive) and returns the details of each item
var_dump($ftp->scanDir('.', true));

支持并改进了所有FTP PHP函数

// Requests execution of a command on the FTP server
$ftp->exec($command);

// Turns passive mode on or off
$ftp->pasv(true);

// Set permissions on a file via FTP
$ftp->chmod(0777, 'file.php');

// Removes a directory
$ftp->rmdir('path/of/directory/to/remove');

// Removes a directory (recursive)
$ftp->rmdir('path/of/directory/to/remove', true);

// Creates a directory
$ftp->mkdir('path/of/directory/to/create');

// Creates a directory (recursive),
// creates automaticaly the sub directory if not exist
$ftp->mkdir('path/of/directory/to/create', true);

// and more ...

获取远程FTP服务器的帮助信息

var_dump($ftp->help());

结果

array (size=6)
  0 => string '214-The following SITE commands are recognized' (length=46)
  1 => string ' ALIAS' (length=6)
  2 => string ' CHMOD' (length=6)
  3 => string ' IDLE' (length=5)
  4 => string ' UTIME' (length=6)
  5 => string '214 Pure-FTPd - http://pureftpd.org/' (length=36)

注意：结果取决于FTP服务器。

扩展

创建您自定义的FtpClient。

// MyFtpClient.php

/**
 * My custom FTP Client
 * @inheritDoc
 */
class MyFtpClient extends \FtpClient\FtpClient {

  public function removeByTime($path, $timestamp) {
      // your code here
  }

  public function search($regex) {
      // your code here
  }
}

// example.php
$ftp = new MyFtpClient();
$ftp->connect($host);
$ftp->login($login, $password);

// remove the old files
$ftp->removeByTime('/www/mysite.com/demo', time() - 86400));

// search PNG files
$ftp->search('/(.*)\.png$/i');
