In this issue, the editor will bring you about how to use unlink to delete folders in php. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

The method to delete a folder using unlink in php: [if ($handle = opendir ("$dirName")) {while (false! = ($item = readdir ($handle) {if ($item...].

Deleting files in PHP is actually a very simple thing, because PHP has prepared the appropriate functions for us, the unlink and rmdir functions. The recursive delete operation can also be completed by using these two functions.

Next, let's take a look at the specific implementation code!

The implementation code is as follows:

All files in the class shanchu {/ / circular 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/$item") } else {/ / Open source code phpfensi.com if (unlink ("$dirName/$item")) echo "successfully deleted file: $dirName/$itemn";} closedir ($handle);}

Suppose you need to delete all the files in a directory called "upload", but you don't need to delete the directory folder, you can do it with the following code:

Php deletes all directories as follows:

Function deltree ($pathdir) {echo $pathdir;// if (is_empty_dir ($pathdir)) / / if it is empty {rmdir ($pathdir); / / directly delete} else {/ / otherwise read this directory, except. And... Outside $d=dir ($pathdir); while ($if ($pathdir.'/'.$a)-> read ()) {unlink ($pathdir.'/'.$a) } / / if it is a file, delete if directly (is_dir ($pathdir.'/'.$a) & & ($astute roomroom.`) & ($astute roomroom.directory) {/ / if it is a directory if (! is_empty_dir ($pathdir.'/'.$a)) / / whether it is empty {/ / if not, call itself, but the original path + his subordinate directory name deltree ($pathdir.'/'.$a) } if (is_empty_dir ($pathdir.'/'.$a)) {/ / delete rmdir ($pathdir.'/'.$a) directly if it is empty;} $d-> close (); echo "must delete all files in the directory first"; / /}} function is_empty_dir ($pathdir) {/ / determine whether the directory is empty $d=opendir ($pathdir); $iTun0; while ($a=readdir ($d)) {$icalendar;} closedir ($d) If ($I > 2) {return false;} else return true;}

PHP deletes the directory and all files under the directory, as follows:
