php deleting a specific folder and all its contents
Question
I'm using php to delete folders containing images of posts that where deleted. I'm using the code below which I found online and does a good job.
I want to know how can I delete only a specific folder in a folder when there are other folders in it.
When I using the code below, how is it possible to do this? Using: /dev/images/norman/8 -> Will not delete folder 8 Using: /dev/images/norman/ -> Will delete all folders
Eg:
/dev/images/norman/8 -> I need to delete only this folder
/dev/images/norman/9
/dev/images/norman/10
/dev/images/norman/11
/dev/images/norman/12
<?php
$path = $_SERVER['DOCUMENT_ROOT'].'/dev/images/norman/8';
emptyDir($path);
function emptyDir($path) {
// INITIALIZE THE DEBUG STRING
$debugStr = '';
$debugStr .= "Deleting Contents Of: $path<br /><br />";
// PARSE THE FOLDER
if ($handle = opendir($path)) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
// IF IT"S A FILE THEN DELETE IT
if(is_file($path."/".$file)) {
if(unlink($path."/".$file)) {
$debugStr .= "Deleted File: ".$file."<br />";
}
} else {
// IT IS A DIRECTORY
// CRAWL THROUGH THE DIRECTORY AND DELETE IT'S CONTENTS
if($handle2 = opendir($path."/".$file)) {
while (false !== ($file2 = readdir($handle2))) {
if ($file2 != "." && $file2 != "..") {
if(unlink($path."/".$file."/".$file2)) {
$debugStr .= "Deleted File: $file/$file2<br />";
}
}
}
}
if(rmdir($path."/".$file)) {
$debugStr .= "Directory: ".$file."<br />";
}
}
}
}
}
echo $debugStr;
}
?>

<?php
delete_directory($dirname) {
if (is_dir($dirname))
$dir_handle = opendir($dirname);
if (!$dir_handle)
return false;
while($file = readdir($dir_handle)) {
if ($file != "." && $file != "..") {
if (!is_dir($dirname."/".$file))
unlink($dirname."/".$file);
else
delete_directory($dirname.'/'.$file);
}
}
closedir($dir_handle);
rmdir($dirname);
return true;
}
?>
if you are using, version 5.1 and above,
<?php
function deleteDir($dir) {
$iterator = new RecursiveDirectoryIterator($dir);
foreach (new RecursiveIteratorIterator($iterator, RecursiveIteratorIterator::CHILD_FIRST) as $file)
{
if ($file->isDir()) {
rmdir($file->getPathname());
} else {
unlink($file->getPathname());
}
}
rmdir($dir);
}
deleteDir("temporary");
?>

You want to hear about rmdir .
if(is_file($path."/".$file)) {
if(unlink($path."/".$file)) {
$debugStr .= "Deleted File: ".$file."<br />";
}
} else {
if(rmdir($path."/".$file)) {
$debugStr .= "Deleted Directory: ".$file."<br />";
}
}
EDIT: as rmdir can only handle empty dirs, you may use this solution as reported in rmdir's page comments:
function rrmdir($dir) {
foreach(glob($dir . '/*') as $file) {
if(is_dir($file))
rrmdir($file);
else
unlink($file);
}
rmdir($dir);
}
It just recursively deletes everything in $dir , then gets rid of directory itself.

You can use system commands ex. exec("rm -rf {$dirPath}"); or if you want to do it by PHP you have to go recursive, loops won't do it right.
public function deleteDir($path) {
if ($handle = opendir($path)) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
// IF IT"S A FILE THEN DELETE IT
if(is_file($path."/".$file)) {
if(unlink($path."/".$file)) {
$debugStr .= "Deleted File: ".$file."<br />";
}
} else {
deleteDir($path."/".$file."/");
rmdir($path."/".$file);
}
}
}
}
}
When I using the code below, how is it possible to do this? Using: /dev/images/norman/8 -> Will not delete folder 8 Using: /dev/images/norman/ -> Will delete all folders
I think your problem is that you're missing "/" at the end of "/dev/images/norman/8"

I added an $exclude param to your function, this param it's an array with the names of directories you want to exclude from being deleted, like so:
$path = $_SERVER['DOCUMENT_ROOT'].'/dev/images/norman/';
emptyDir($path); //will delete all under /norman/
emptyDir($path, array('8')); //will delete all under /norman/ except dir 8
emptyDir($path, array('8','10')); //will delete all under /norman/ except dir 8 and 10
function emptyDir($path,$exclude=false) {
// INITIALIZE THE DEBUG STRING
$debugStr = '';
$debugStr .= "Deleting Contents Of: $path<br /><br />";
if (!$exclude) {
$exclude = array();
}
// PARSE THE FOLDER
if ($handle = opendir($path)) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
// IF IT"S A FILE THEN DELETE IT
if(is_file($path."/".$file)) {
if(unlink($path."/".$file)) {
$debugStr .= "Deleted File: ".$file."<br />";
}
} else if (!in_array($file, $exclude)) {
// IT IS A DIRECTORY
// CRAWL THROUGH THE DIRECTORY AND DELETE IT'S CONTENTS
if($handle2 = opendir($path."/".$file)) {
while (false !== ($file2 = readdir($handle2))) {
if ($file2 != "." && $file2 != "..") {
if(unlink($path."/".$file."/".$file2)) {
$debugStr .= "Deleted File: $file/$file2<br />";
}
}
}
}
if(rmdir($path."/".$file)) {
$debugStr .= "Directory: ".$file."<br />";
}
}
}
}
}
echo $debugStr;
}

$path='./ggg';
rrmdir($path);
function rrmdir($dir) {
if (is_dir($dir)) {
$objects = scandir($dir);
foreach ($objects as $object) {
if ($object != "." && $object != "..") {
if (filetype($dir."/".$object) == "dir") rrmdir($dir."/".$object); else unlink($dir."/".$object);
}
}
reset($objects);
rmdir($dir);
}
