HTML static pages are generated when you add an article, but if you want to delete an article, the HTML static page generated when you add the article should also be deleted, otherwise it becomes a redundant file, so we should delete the useless article while deleting the generated HTML static page, below to see how the PHP article system inside how to delete the generated HTML static page, here is just a simple principle system, can be used as a reference, more mature system can refer to a more mature CMS system, the following is the source file.

Ob_start ();

Require_once (". /inc/conn.php ");

$id =$_get["id"];

$path =$_get["path"];

$sql = "Delete from newscontent where newsid= $id";

mysql_query ($sql);

if (file_exists. /newslist/$path "))

{

Unlink (". /newslist/$path ");

$foldername =substr ($path, 0,10);

$folder =fopen (". /newslist/$foldername ");

$n = 0;

while ($f =readdir ($folder))

{

if ($f <> "." && $f <> "...")

{

$n + +;

}

}

Closedir ();

if ($n ==0)

{

RmDir (". /newslist/$foldername ");

}

}

Header ("location:del.php");

?>

The while statement here is a read directory and does not need to be understood in depth.

A perfect article generation of HTML static page system should be, add the article while generating static HTML file, update the article also update the generated HTML static page, delete the generated HTML static page deleted at the same time, update the static page to regenerate the site is not introduced here, With the addition of the article is a truth, is to judge the $path of the article, and then the corresponding regeneration on the line, but to the static file write permission, otherwise update, delete static HTML article also want to give full permission, otherwise it will be wrong.
