HomeBackend DevelopmentPHP TutorialHow to create a multi-level directory with complete encapsulation classes in PHP

本篇文章主要介绍php创建多级目录完整封装类的方法,感兴趣的朋友参考下,希望对大家有所帮助。

创建多级目录函数中调用创建指定下的指定文件的函数:

 public function create_dir($dir,$mode=0777)
  {
    return is_dir($dir) or ($this->create_dir(dirname($dir)) and mkdir($dir, $mode));
  }

创建指定路径下的指定文件,string 需要包含文件名和后缀path(需要包含文件名和后缀),booleanover_write 是否覆盖文件,int 设置时间。默认是当前系统时间time设置时间。默认是当前系统时间,intatime 设置访问时间。默认是当前系统时间。函数如下中调用了create_dir创建目录函数及删除unlink_file函数:

public function create_file($path,$over_write=FALSE,$time=NULL,$atime=NULL)
  {
    $path = $this->dir_replace($path);
    $time = empty($time) ? time() : $time;
    $atime = empty($atime) ? time() : $atime;
    if(file_exists($path) && $over_write)
    {
      $this->unlink_file($path);
    }
    $aimDir = dirname($path);
    $this->create_dir($aimDir);
    return touch($path,$time,$atime);
  }

删除非空目录函数,说明:只能删除非系统和特定权限的文件,否则会出现错误,string目录路径dirName目录路径,booleanis_all是否删除所有,boolean $del_dir 是否删除目录,函数如下:

public function remove_dir($dir_path,$is_all=FALSE)
  {
    $dirName = $this->dir_replace($dir_path);
    $handle = @opendir($dirName);
    while (($file = @readdir($handle)) !== FALSE)
    {
      if($file != '.' && $file != '..')
      {
        $dir = $dirName . '/' . $file;
        if($is_all)
        {
          is_dir($dir) ? $this->remove_dir($dir) : $this->unlink_file($dir);
        }
        else 
        {
          if(is_file($dir))
          {
            $this->unlink_file($dir);
          }
        }
      }
    }
    closedir($handle);
    return @rmdir($dirName);
  }

替换路径中//的字符相应的字符函数:

public function dir_replace($path)
  {
    return str_replace('//','/',str_replace('\\','/',$path));
  }

/**
   * 指定文件编码转换
   * @param string $path 文件路径
   * @param string $input_code 原始编码
   * @param string $out_code 输出编码
   * @return boolean
   */
  public function change_file_code($path,$input_code,$out_code)
  {
    if(is_file($path))//检查文件是否存在,如果存在就执行转码,返回真
    {
      $content = file_get_contents($path);
      $content = string::chang_code($content,$input_code,$out_code);
      $fp = fopen($path,'w');
      return fputs($fp,$content) ? TRUE : FALSE;
      fclose($fp);
    }
  }

/**
* 取得上传文件信息
* @param $file file属性信息
* @return array
*/

public function get_upload_file_info($file)
  {
    $file_info = $_FILES[$file];//取得上传文件基本信息
    $info = array();
    $info['type'] = strtolower(trim(stripslashes(preg_replace("/^(.+?);.*$/", "\\1", $file_info['type'])), '"'));//取得文件类型
    $info['temp'] = $file_info['tmp_name'];//取得上传文件在服务器中临时保存目录
    $info['size'] = $file_info['size'];//取得上传文件大小
    $info['error'] = $file_info['error'];//取得文件上传错误
    $info['name'] = $file_info['name'];//取得上传文件名
    $info['ext']  = $this->get_ext($file_info['name']);//取得上传文件后缀
    return $info;
  }

/**
* 取得文件路径信息
* @param $full_path 完整路径
* @return ArrayObject
*/

public function get_file_type($path)
  {
    //pathinfo() 函数以数组的形式返回文件路径的信息。
    //---------$file_info = pathinfo($path); echo file_info['extension'];----------//
    //extension取得文件后缀名【pathinfo($path,PATHINFO_EXTENSION)】-----dirname取得文件路径【pathinfo($path,PATHINFO_DIRNAME)】-----basename取得文件完整文件名【pathinfo($path,PATHINFO_BASENAME)】-----filename取得文件名【pathinfo($path,PATHINFO_FILENAME)】
    return pathinfo($path);
  }

/**
* 返回指定文件和目录的信息
* @param string $file
* @return ArrayObject
*/

public function list_info($file)
  {
    $dir = array();
    $dir['filename']  = basename($file);//返回路径中的文件名部分。
    $dir['pathname']  = realpath($file);//返回绝对路径名。
    $dir['owner']   = fileowner($file);//文件的 user ID (所有者)。
    $dir['perms']   = fileperms($file);//返回文件的 inode 编号。
    $dir['inode']   = fileinode($file);//返回文件的 inode 编号。
    $dir['group']   = filegroup($file);//返回文件的组 ID。
    $dir['path']    = dirname($file);//返回路径中的目录名称部分。
    $dir['atime']   = fileatime($file);//返回文件的上次访问时间。
    $dir['ctime']   = filectime($file);//返回文件的上次改变时间。
    $dir['perms']   = fileperms($file);//返回文件的权限。 
    $dir['size']    = filesize($file);//返回文件大小。
    $dir['type']    = filetype($file);//返回文件类型。
    $dir['ext']    = is_file($file) ? pathinfo($file,PATHINFO_EXTENSION) : '';//返回文件后缀名
    $dir['mtime']   = filemtime($file);//返回文件的上次修改时间。
    $dir['isDir']   = is_dir($file);//判断指定的文件名是否是一个目录。
    $dir['isFile']   = is_file($file);//判断指定文件是否为常规的文件。
    $dir['isLink']   = is_link($file);//判断指定的文件是否是连接。
    $dir['isReadable'] = is_readable($file);//判断文件是否可读。
    $dir['isWritable'] = is_writable($file);//判断文件是否可写。
    $dir['isUpload']  = is_uploaded_file($file);//判断文件是否是通过 HTTP POST 上传的。
    return $dir;
  }

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.

PHP Dependency Injection: Boost Code MaintainabilityPHP Dependency Injection: Boost Code MaintainabilityMay 07, 2025 pm 02:37 PM

Dependency injection provides object dependencies through external injection in PHP, improving the maintainability and flexibility of the code. Its implementation methods include: 1. Constructor injection, 2. Set value injection, 3. Interface injection. Using dependency injection can decouple, improve testability and flexibility, but attention should be paid to the possibility of increasing complexity and performance overhead.

How to Implement Dependency Injection in PHPHow to Implement Dependency Injection in PHPMay 07, 2025 pm 02:33 PM

Implementing dependency injection (DI) in PHP can be done by manual injection or using DI containers. 1) Manual injection passes dependencies through constructors, such as the UserService class injecting Logger. 2) Use DI containers to automatically manage dependencies, such as the Container class to manage Logger and UserService. Implementing DI can improve code flexibility and testability, but you need to pay attention to traps such as overinjection and service locator anti-mode.
