PHP loops Delete directories and files in directories

Share two usage functions: PHP loop Delete directories and directories under the file and only delete files under the specified directory, do not delete the directory folder!

Code One: PHP loop delete directories and files under the directory

<?php

Loop Delete directory and file functions

function Deldirandfile ($dirName)

{

if ($handle = Opendir ("$dirName")) {

while (false!== ($item = Readdir ($handle))) {

if ($item! = "." && $item! = "...") {

if (Is_dir ("$dirName/$item")) {

Deldirandfile ("$dirName/$item");

} else {

if (unlink ("$dirName/$item")) echo "Successfully deleted files: $dirName/$item <br/>n";

}

}

}

Closedir ($handle);

if (RmDir ($dirName)) echo "Successfully deleted directory: $dirName <br/>n";

}

}

?>

Code two: Delete only the files under the specified directory, do not delete the directory folder.

All files in the loop directory

function Delfileunderdir ($dirName = ": /smarty/templates/templates_c ")

{

if ($handle = Opendir ("$dirName")) {

while (false!== ($item = Readdir ($handle))) {

if ($item! = "." && $item! = "...") {

if (Is_dir ("$dirName/$item")) {

Delfileunderdir ("$dirName/$item");

} else {

if (unlink ("$dirName/$item")) echo "Successfully deleted files: $dirName/$item <br/>n";

}

}

}

Closedir ($handle);

}

}

How to call it needless to say, Haha, a friend who encounters a similar problem can try the amount!
