This is the deldir() function. The function of this function is to delete files

function deldir($dir){

If(is_dir($dir)){

         $rdir = $dir;

If($dirlist = scandir($rdir)){ //Scan directory
                 array_shift($dirlist);Remove ".."
                 array_shift($dirlist);Remove "."
foreach($dirlist as $d){

           $rd = $rdir.'/'.$d;

If(isset($d) && is_file($rd)){

​​​​​unlink($rd);//Delete file

           }else{

​​​​​deldir($rd);//Recursion

         }

                                                                                               

​​​​​​ rmdir($rdir);//Delete empty directories

         }else{

              return false;

}

}

Return true;

}

This function also uses a recursive algorithm to delete directories and files,

The following is the filename() function. The function of this function is to rename the file

function Filename($path,$nname){

// Get the old file name

if($path == "" || substr($path,-1) ==="/" || strlen($path)>255){

exit('Illegal operation!');

}else{

$oname = substr($path,strrpos($path,"/")+1);
$opath = substr($path,0,strlen($path) - strlen(substr($path,strrpos($path,"/")+1)));//Get the current path of the file

}

//Rename

if(preg_match("/^w{1,255}.w{1,8}$/i",$nname,$temp_name) && preg_match("/^w{1,255}.w{1,8}$ /i",$oname,$otemp_name)){ //Match file name

Rename_file_folder($path,$opath,$nname);//These functions are discussed below

}else if( preg_match("/^w{1,255}$/i",$nname,$temp_name) && preg_match("/^w{1,255}$/i",$oname,$otemp_name)){ //Match folder name

Rename_file_folder($path,$opath,$nname);
}else{
echo("File info Error");

}}

function Rename_file_folder($path,$opath,$newname){

if(is_dir($path)){
if(is_writable($path)){

if(is_dir($opath.$newname)){ exit("Sorry Dir is exists");}

echo rename($path,$opath.$newname)?'Rename Success':'Rename Fail Error';
}else{
echo('Can't Rename dir not is_writable');

}

}else{
if(file_exists($path) && is_writable($path)){
if(file_exists($opath.$newname)){ exit("file exists"); }
echo rename($path,$opath.$newname)?'Rename success ':'Rename fail';
}else{
echo "file can't is_writable";
}
}

}
