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;
}
}
?>

// 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;
