A guess really,

If I do:
...
if (file_exists($filename))
{

and followed by
...
   @unlink($filename);
}

And that gives me a

unlink(/home/xxx/public_html/temp/yyy.zz) [function.unlink]: No such 
file or directory

The something between file_exists(...) and @unlink(...) must have 
removed the file.
Either that or one of the two functions is not working as expected.

As per the doc, http://php.net/manual/en/function.clearstatcache.php, to 
make sure that file_exists($filename) does return a cached value.

Because the warnings fill my logs and I aim for no warnings at all.
