If there are any mistakes, please correct me and learn together
*/
header("Content-type: text/html; charset=gb2312");

function delete_dir($tmp_path){

if(!is_writable($tmp_path) && is_dir($tmp_path)){
chmod($tmp_path,0777);
}

$encode = mb_detect_encoding ($tmp_path, array('UTF-8','GB2312','ASCII','GBK'));
$tmp_path = iconv($encode,'gb2312',$tmp_path);

$handle_object = scandir($tmp_path);

if(count(scandir($tmp_path))==2){

if(rmdir($tmp_path) ){
                                                                                          echo $tmp_path.' return ;

}

foreach($handle_object as $val){

if($val!='..' && $val!='.' && $ val!=''){

If(filetype($tmp_path.'/'.$val)=='dir'){

If(count(scandir($tmp_path.' /not)) == 2) {
IF (RMDIR ($ tmp_path. '/'. $ Val)) {
echo $ $ tmp_path. '/'. $ val. '& lt; br /& gt; ';
} else {
echo $ $ tmp_path.' /'. $ value.' & lt; br /& gt; '; $tmp_path.'/'.$val);
                                                                                                                                                    echo $$tmp_path.'/ '. $ value.' & lt; br /& gt; ';
} else {

echo $ tmp_path.'
';
}else{

}

delete_dir('D:/AppServ/www/testing/haha');

?>

Example 3: Parameter $dir file name example: admin/runtime like this

Copy code

The code is as follows:

//Delete directory and contained files function
function deldir($dir) {
//Open file directory
$dh = opendir($dir);
// Loop through reading files
while ($file = readdir($dh)) {
if($file != '.' && $file != '..') {
$fullpath = $dir . '/' . $file;

// Determine if it is a directory
if(!is_dir($fullpath)) {
echo $fullpath."Deleted
";
} else { > dir ($dir)) {
// return true;
// } else {
// return false;
// }
}

Example 4:

Copy code

The code is as follows:

function deldir($dirname){ if (file_exists($dirname)){//First determine whether the directory is valid

Use readdir to loop through the contents of the directory

if($filename != "." && $filename != ".."){//Exclude the two special directories "." and ".."

Use recursion to delete subdirectories > closedir($dir);//Close the file Operation handle rmdir($dirname);//Delete directory } } ?>

Example 5:

Copy code

The code is as follows:

/**
* Delete non-empty directory
* @method rrmdir
*/
function rrmdir ($dir) {

if (is_dir($dir)) {

$fs = array_slice(scandir($dir), 2);
foreach ($fs as $f) {
$path = $dir . '/' . $f;
is_dir( $path) ? rrmdir($path) : unlink($path);
}
reset($fs);
return rmdir($dir);
}

}

Example 6:

Copy code The code is as follows:

function del_dir( $dir )
{
if ( $handle = opendir( $dir ) )
{
while ( false !== ( $item = readdir( $handle ) ) )
{
if ( $item != "." && $item != ".." )
;
( $handle );
rmdir( $dir ) ;

}
}
