//Delete subdir
if(file_exists($sSubDir) && $sSubDir!="." && $sSubDir != ".."){
	rmdir($sSubDir);
}

...better.

I have a specific subdirectory on my site where users can upload images
files associated with some text stored in a database. The question
concerns
deleting those uploaded images. Deleting the record is the easy
part...even
deleting the images and subdirectory is easy. However, my concern is
what
precautions should I take to make sure that the wrong subdir (or the
whole
site!!) doesn't get blown away. In the code below I'm using file_exists
to
delete the images and subdir but is there anything else that I should do
to
bullet proof the procedure? 

//Note: $sSubDir is the subdirectory path stored in the corresponding
MySQL
record.

//Delete images
for($i=0;$i<5;$i++){
		$sImageName = $sSubDir . "image$i.jpg";
		if(file_exists($sImageName)){		
			unlink($sImageName);
		}	
	}
//Delete subdir
if(file_exists($sSubDir)){
	rmdir($sSubDir);
}
