How 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 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.
