File directory operation class implemented by php

/**
 * File directory operation class
 * Editor: bbs.it-home.org
 * Example:
 * $fileutil = new fileDirUtil();
 * $fileutil->createDir('a/1/2/3') ; To test the creation folder, create a/1/2/3 folder
 * $fileutil->createFile('b/1/2/3'); To test the creation file, create it under the b/1/2/ folder A 3-file
 * $fileutil->createFile('b/1/2/3.txt'); To test the creation file, create a 3.exe file under the b/1/2/ folder
 * $fileutil-> ;writeFile('b/1/2/3.txt','this is something i write!'); Write content in the file
 * $arr = $fileutil->readFile2array('example/mysql.txt') ;
 * $arr = $fileutil->readsFile('example/mysql.txt');
 * $size=$fileutil->bitSize($fileutil->getDirSize("example")); Get the file or The size of the directory
 * $fileutil->copyDir('b','d/e'); Test the copy folder to create a d/e folder and copy the contents of the b folder into it
 * $fileutil-> ;copyFile('b/1/2/3.exe','b/b/3.exe'); Test copy the file to create a b/b folder, and put 3. in the b/1/2 folder. Copy the exe file into it
 * $fileutil->moveDir('a/','b/c'); Test the moving folder, create a b/c folder, move the contents of the a folder into it, and delete it a folder
 * $fileutil->moveFile('b/1/2/3.exe','b/d/3.exe'); Test moving files to create a b/d folder and put b/ Move the 3.exe in 1/2 in
 * $fileutil->unlinkFile('b/d/3.exe'); Test deletion of the file and delete the b/d/3.exe file
 * $fileutil->unlinkDir ('d'); Test deletion folder to delete d folder
 * $list = $fileutil->dirList("E:example"); Test list folder to list all files in the directory
 * $list = $fileutil ->dirTree("/"); Test list folder tree lists the direct tree relationship of all files in the directory
