php delete folder and all files under it_PHP tutorial

We use unlink deletion to delete files and directories in php. If we want to delete a directory that is not empty, we mainly use readdir and opendir to traverse the directory.

The code is as follows

代码如下	复制代码
// 删除文件夹，及其其下所有文件 function deldir($dir) { $dh=opendir($dir); while ($file=readdir($dh)) { if($file!="." && $file!="..") { $fullpath=$dir."/".$file; if(!is_dir($fullpath)) { unlink($fullpath); } else { deldir($fullpath); } } } closedir($dh); if(rmdir($dir)) { return true; } else { return false; } } ?>

Copy code

// Delete the folder and all files under it

function deldir($dir) {

$dh=opendir($dir);

while ($file=readdir($dh)) {

If($file!="." && $file!="..") {
​
$fullpath=$dir."/".$file;
​
If(!is_dir($fullpath)) {
           
              unlink($fullpath);
           
} else {
           
​ ​ ​ deldir($fullpath);
           
} }
​
}

}

closedir($dh);

if(rmdir($dir)) {

Return true;

} else {

Return false;

} }
