PHP function code for operating file classes (file and folder creation, copying, moving and deletion)_PHP tutorial

/**
* Manipulate file class
*
* Example:
* FileUtil::createDir('a/1/2/3'); Test to create a folder and create a/1/2/3 Folder
* FileUtil::createFile('b/1/2/3'); To test the creation of files, create a 3-file file under the b/1/2/ folder
* FileUtil::createFile('b /1/2/3.exe'); To test the creation file, create a 3.exe file under the b/1/2/ folder
* 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 files to create a b/b folder, and copy the 3.exe file in the b/1/2 folder into it
* FileUtil::moveDir('a/','b/c' ); Test the moving folder to create a b/c folder, move the contents of the a folder into it, and delete the a folder
* FileUtil::moveFile('b/1/2/3.exe' ,'b/d/3.exe'); Test moving files to create a b/d folder and move 3.exe in b/1/2 into it
* FileUtil::unlinkFile('b/d /3.exe'); Test deleting files to delete b/d/3.exe files
* FileUtil::unlinkDir('d'); Test deleting folders to delete d folders
