About directory operations in PHP

This article mainly introduces PHP directory operations. It summarizes and analyzes PHP's related functions and usage skills for common operations such as directory reading, traversal, and closing in the form of examples. Friends in need can refer to it

The example in this article summarizes the PHP directory operation method. Share it with everyone for your reference, the details are as follows:

Directory operation

New directory: mkdir (path, permissions, recursive creation)

Delete directory: rmdir()

Move (rename): rename()

Get directory content：

//Open directory

Directory handle = opendir()

//Read directory

File name = readdir(directory handle)

Read the file names in sequence and move the file handle pointer downward at the same time. If it cannot be read, return false

//Close the directory

closedir()

Recursively read the directory content:

'; if(is_dir($path.'/'.$file)){ $func = __FUNCTION__; $func($path.'/'.$file,$dep+1); } } }

The running effect is as follows:

'; print_r($res); function showDir($path){ $pos = opendir($path); $next = array(); while(false!==$file=readdir($pos)){ if($file=='.'||$file=='..') continue; $fileinfo = array(); $fileinfo['name'] = $file; if(is_dir($path.'/'.$file)){ $fileinfo['type'] = 'dir'; $func = __FUNCTION__; $fileinfo['next'] = $func($path.'/'.$file); }else{ $fileinfo['type'] = 'file'; } $next[] = $fileinfo; } closedir($pos); return $next; }

The running effect diagram is as follows:

Recursively delete the directory:

'; if(is_dir($path.'/'.$file)){ $func = __FUNCTION__; $func($path.'/'.$file,$dep+1); }else{ unlink($path.'/'.$file); } } rmdir($path); closedir($pos); }

Directory file encoding problem:

Convert operating system encoding to response data encoding when displaying

windows For gbk, the project utf-8

iconv('gbk',utf-8',file);

code address exists in Chinese: it needs to be converted to system encoding

iconv(utf-8','gbk',file);
