First of all, we would like to show you how to delete only files from a folder.

<?php

//The name of the folder.
$folder = 'files';

//Get a list of all of the file names in the folder.
$files = glob($folder . '/*');

//Loop through the file list.
foreach($files as $file){
//Make sure that this is a file and not a directory.
if(is_file($file)){
//Use the unlink function to delete the file.
unlink($file);
}
}

Earlier we have seen about deleting just files which are present in a directory. Now, What if you have sub directories with files inside the folder. In that case the above script won’t able to work. You’ll need to create recursive function to delete all files, sub-directories and parent directory altogether.

Simply deleting a folder with using php’s function rmdir() won’t work. It will throw some exceptions if you attempt to remove folder directly with files in it. So first of all you have to delete files one by one from each sub folder and then delete folders by removing parent folder.

So, here is the recursive function to delete files and sub folders from the folder.

<?php
// delete all files and sub-folders from a folder
function deleteAll($dir) {
foreach(glob($dir . '/*') as $file) {
if(is_dir($file))
deleteAll($file);
else
unlink($file);
}
rmdir($dir);
}
?>

This is the function which will help you out to delete folder and sub folders and also files. You can use this function by simply calling:

<?php deleteAll('folder_name'); ?>

The function above basically checks to see if the $file variable represents a path to a file. If it does represent a path to a file, it deletes the file using the function unlink. However, if $file represents a directory, then it gets a list of all files in said directory before deleting each one. Finally, it removes the sub-directory itself by using PHP’s rmdir function.

You can use the above php script to delete files and sub-directories in a given folder programmatically. The script is relatively fast but it depends on the amount of files and folders to be deleted.

function EmptyDir($dir) {

$handle=opendir($dir);


while (($file = readdir($handle))!==false) {

echo "$file <br>";

@unlink($dir.'/'.$file);

}

closedir($handle);

}

EmptyDir('images');

echo "<form method=post name='f1' action=''>";
while (list ($key, $val) = each ($ar)) {
if(strlen($val)>3){
echo "<input type=checkbox name=box[] value='$val'>$val<br>";
}
}
echo "<input type=submit value='Delete'></form>";

while (list ($key,$val) = @each ($box)) {
$path=$dir	."/".$val;
if(unlink($path)) echo "Deleted file ";
echo "$val,";
}

<?Php
$dir='test_dir'; // directory name 
$ar=scandir($dir); 
$box=$_POST['box'];  // Receive the file list from form

// Looping through the list of selected files ///
while (list ($key,$val) = @each ($box)) {
$path=$dir	."/".$val;
if(unlink($path)) echo "Deleted file ";
echo "$val,";
}
echo "<hr>";

/// displaying the file names with checkbox and form ////
echo "<form method=post name='f1' action=''>";
while (list ($key, $val) = each ($ar)) {
if(strlen($val)>3){
echo "<input type=checkbox name=box[] value='$val'>$val<br>";
}
}
echo "<input type=submit value='Delete'></form>";
?>

$ar=scandir($dir);

<?Php
$dir='test_dir'; // directory name 
$ar=scandir($dir); 
$box=$_POST['box'];  // Receive the file list from form

// Looping through the list of selected files ///
while (list ($key,$val) = @each ($box)) {
$path=$dir	."/".$val;
if(unlink($path)) echo "Deleted file ";
echo "$val,";
}
echo "<hr>";
$ar=scandir($dir);// Once again directory content is scanned to exclude deleted files. 
/// displaying the file names with checkbox and form ////
echo "<form method=post name='f1' action=''>";
while (list ($key, $val) = each ($ar)) {
if(strlen($val)>3){
echo "<input type=checkbox name=box[] value='$val'>$val<br>";
}
}
echo "<input type=submit value='Delete'></form>";
?>
