php recursively delete the directory (folder)

recursive delete directory (folder) Here are two examples, one is to delete a separate empty directory code, a batch delete directory folder code.

// delete a single empty folder

$ dir = 'www.111cn.net';
if (is_dir ($ dir)) / / to determine whether the directory
{
if (rmdir ($ dir))
{
Echo 'directory deleted successfully';
}
else
{
echo 'did not delete the directory permissions';
}
}
else
{
echo 'is not a valid directory';
}
Let's look at a batch recursive delete function of the directory.

function deletedir ($ dir) {
if (! handle = @ opendir ($ dir)) {// Check if the directory to open exists
die ("no such directory");
}
while (false! == ($ file = readdir ($ handle))) {
if ($ file! == "." && $ file! == "..") {// exclude the current directory from the parent directory
$ file = $ dir .directory_separator. $ file;
if (is_dir ($ file)) {
deletedir ($ file);
} else {
if (@unlink ($ file)) {
echo "file <b> $ file </ b> deleted successfully."
} else {
echo "file <b> $ file </ b> failed to delete! <br>";
}
}
}
if (@rmdir ($ dir)) {
echo "directory <b> $ dir </ b> deleted successfully. <br> n";
} else {
echo "directory <b> $ dir </ b> failed to delete! <br> n";
}
}

//test program
$ dir = "/ var / www / test";
deletedir ($ dir);
