Removing folder content

[oceans]

Dear Friends,

 

A member gave me this code

 

function delete_folder($folder)
{
if(!is_dir($folder))
{
	trigger_error("'{$folder}' is not a folder", E_USER_ERROR);
	return false;
}
$folder = str_replace('\\', '/', $folder);

if($folder[strlen($var)-1] == '/')
{
	$folder = substr($folder,0,strlen($folder)-1);
}
$dh = opendir($folder);
while($item = readdir($dh))
{
	if($item == '.' || $item == '..')
	{
		continue;
	}
	if(is_dir("{$folder}/{$item}"))
	{
		delete_folder("{$folder}/{$item}");
	}
	else 
	{
		unlink("{$folder}/{$item}");
	}
}
closedir($dh);
return rmdir($folder);
}

but some times, this removes not only the folder but also the parent folder, I can't understand, can any one help me to see why. thanks.

Well if it only does it sometimes that would lead me to believe it is a problem with the argument you are butting in for delete_folder($folder);

 

I looked at your code but don't see anything wrong at a glance, then again my scripts rarely require me to dable in directory modification

Dear SMC,

 

I will give you an example:

 

C:\grandparent\parent\folder

 

I want to remove "folder" and its entire content, but leave C:\grandparent\parent alone.

 

The problem is, it works fine and not fine somtimes.

 

Can you suggest me please.

 

the idea is to remove "folder" and its entire content, I did tried deleting using simple php comand, but then i had another problem, that is if the folder is not empty this php comand gives error mentioning the folder is not empty.

OK Friends,

 

I found the staff, the function is working perfectly as intended.

 

Idea is to delete the folder and its entire contant!

 

When I call this function, I call it like this

 

delete_folder("NewFolder/".$ID);

 

I think, if by chance $ID is "" (i.e. empty), the NewFolder gets deleted.

(Please correct me if I am wrong).

Can we make an addition in the function to say if the folder name is "NewFolder" don't delete it, will this help?
