php ftp 建立多个目录

Question

这是我的 PHP 代码。实际上效果很好：

            $newftpdir_parent   = date('Ymd');                              // YYYYMMDD
            $newftpdir_child    = $ext_folder;                              // username
            $newftpdir          = $newftpdir_parent.'/'.$newftpdir_child;   // YYYYMMDD/username
            $conn_id            = ftp_connect($uptoftp_server);
            ftp_login($conn_id, $uptoftp_username, $uptoftp_pass);

            $path_of_storage    = $uptoftp_path_abs.'/'.$uptoftp_path_rel; // /var/www/uploads
            if( !@ftp_chdir($conn_id, $path_of_storage.'/'.$newftpdir_parent) ){
                  ftp_mkdir($conn_id, $path_of_storage.'/'.$newftpdir_parent);
                  ftp_chmod($conn_id, 0777, $path_of_storage.'/'.$newftpdir_parent);
            }
            if( !@ftp_chdir($conn_id, $path_of_storage.'/'.$newftpdir) ){
                  ftp_mkdir($conn_id, $path_of_storage.'/'.$newftpdir);
                  ftp_chmod($conn_id, 0777, $path_of_storage.'/'.$newftpdir);
            }

            ftp_chdir($conn_id, $path_of_storage.'/'.$newftpdir);

            ftp_put($conn_id, $file_name, $filetoftp, FTP_ASCII);

            ftp_close($conn_id);

它将文件从本地服务器上传到远程 ftp 服务器。正如你所看到的，有 2 个丑陋的 if 条件检查目录是否存在，如果不存在，我们创建它并移入其中。再次针对子目录。由于我现在希望我的目录（在 ftp 服务器上）看起来像 YYYY/MM/DD/username 而不是 YYYYMMDD/username，因此我需要再创建两个这样的 if 块。它工作得很好，但它看起来不干净，我有点疯狂......我想知道是否有更好的方法来做到这一点，因为 ftp_mkdir() 无法创建多个目录（其中包含子目录的目录）？

例如，仅考虑 /uploads/ 目录存在，而不存在 /2013/ 子目录 /06/ 和 /11/ :

ftp_mkdir($conn_id, '/var/www/uploads/2013/06/11');

返回：

Warning: ftp_mkdir() [function.ftp-mkdir]: /var/www/uploads/2013/06/11: No such file or directory in /home/blabla/www/test.php on line 18

<?php

// function
function ftp_mksubdirs($ftpcon,$ftpbasedir,$ftpath){
   @ftp_chdir($ftpcon, $ftpbasedir); // /var/www/uploads
   $parts = array_filter(explode('/',$ftpath)); // 2013/06/11/username
   foreach($parts as $part){
      if(!@ftp_chdir($ftpcon, $part)){
         ftp_mkdir($ftpcon, $part);
         //ftp_chmod($ftpcon, 0775, $part);
         ftp_chdir($ftpcon, $part);
      }
   }
}

// usage
$path_of_storage = '/var/www/uploads';
$newftpdir = '2013/06/11/username';

$conn_id = ftp_connect($ftpserver);
ftp_login($conn_id, $login, $pass);
ftp_mksubdirs($conn_id,$path_of_storage,$newftpdir);
ftp_close($conn_id);

?>

找到这个，也许有帮助：

function ftp_mkdir_recusive($con_id,$path){
    $parts = explode("/",$path);
    $return = true;
    $fullpath = "";
    foreach($parts as $part){
            if(empty($part)){
                    $fullpath .= "/";
                    continue;
            }
            $fullpath .= $part."/";
            if(@ftp_chdir($con_id, $fullpath)){
               ftp_chdir($con_id, $fullpath);
            }else{
                    if(@ftp_mkdir($con_id, $part)){
                            ftp_chdir($con_id, $part);
                    }else{
                            $return = false;
                    }
            }
    }
    return $return;
}

$dir = "/2012/05/02/"

if(ftp_mkdir_recusive($con_id,$dir)){
     print("Successfully created $dir");
}else{
    print("There was a problem while creating $dir");
}

我定义了完整的功能，你可以使用（我在wordpress中测试，使用没有问题）：

function ftp_mksubdirs($con_id,$ftpbasedir,$path){
        // Set Base Dir
        if($ftpbasedir == null || ftp_chdir($con_id, $ftpbasedir)){
            //Check If Path is Exist, 
            $ftp_exist = ftp_nlist($con_id, $path);
            if (is_array($ftp_exist) || (is_bool($ftp_exist) && $ftp_exist == true)){
                // Path Is Exist, Move to $path
                ftp_chdir($con_id, $path);
                return true;
            }
            // Split Path
            $parts = explode("/",$path);
            // Check Part by Part Of Path
            foreach($parts as $part){
                // if Part is not Empty 
                if(!empty($part)){
                    /////////////////////////////
                    ///   ***  Filters  ***   \\\
                    if(str_replace(" ","",$part) != ".."){
                        //Go To Parent Directory
                        ftp_cdup($con_id);
                        // Check Next $part
                        continue;
                    
                    }else if(str_replace(" ","",$part) != ".") {
                        //Ignore & pass
                        continue;
                    }
                    /// *** [END] Filters *** \\\
                    /////////////////////////////
                    // Check If Folder is't Exist
                    $exis = ftp_nlist($con_id, $part);
                    if (is_bool($exis) && $exis == false) {
                        //If Can Make Folder
                        if(ftp_mkdir($con_id, $part)){
                            // Move Directory To this Folder
                            ftp_chmod($con_id, 0777, $part);
                            ftp_chdir($con_id, $part);
                        }
                        else {
                            // We can't Create Folder, Check Your User Permission.
                            return false;
                        }
                    }else{
                        // Folder Existed.
                        // Move Directory To this Folder
                        ftp_chdir($con_id, $part);
                    }
                }
            }// End Foreach
        }else{
            //Can't Set The Base
            // return ftp_mksubdirs($con_id,$ftpbasedir,$path);
        }
        
        return true;
    }

演示使用：

$path = "/hamid/reza/irani";
$conn_id = ftp_connect($ftp_server, $ftp_server_port); 
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
// if you don't need to change base, set it to null; else : Your Path
// -> I Recommend set base path in $BASE; 
$base = null; // or $base = "/";
if(ftp_mksubdirs($con_id, $base, $path )){
     print("Successfully created $dir");
}else{
    print("There was a problem while creating $dir");
}
