Write your own class of PHP file and folder operations (create, delete, move, copy)

/** * Manipulating file Classes * Example * Fileutil::createdir (' A/1/2/3 '); Test build folder Build a A/1/2/3 folder * Fileutil::createfile (' B/1/2/3 '); Test build file Build a 3 file under the b/1/2/folder * Fileutil::createfile (' b/1/2/3.exe '); Test build file Build a 3.exe file under the b/1/2/folder * Fileutil::copydir (' B ', ' d/e '); Test the Replication folder create a d/e folder and copy the contents of the B folder * Fileutil::copyfile (' b/1/2/3.exe ', ' b/b/3.exe '); Test the copy file to create a b/b folder and copy the 3.exe files in the B/1/2 folder * Fileutil::movedir (' A ', ' b/c '); Test the Move folder to create a b/c folder and move the contents of the a folder into the folder and delete the A folders * Fileutil::movefile (' b/1/2/3.exe ', ' b/d/3.exe '); Test the move file to create a b/d folder and move the 3.exe in the B/1/2 * Fileutil::unlinkfile (' b/d/3.exe '); Test Delete file Delete b/d/3.exe file * Fileutil::unlinkdir (' d '); Test Delete folder Delete D folder */ Class Fileutil { /** * Create a folder * * @param string $AIMURL * @return Viod */ function Createdir ($AIMURL) { $AIMURL = Str_replace (', '/', $AIMURL); $aimDir = "; $arr = explode ('/', $AIMURL); $result = true; foreach ($arr as $str) { $aimDir. = $str.
