Storing an image in a database/table field

the unlink will generate php warnings and notices if the file/path supplied to it doesn't exist or the permissions are wrong.

Code:

function deleteFile($strFile)
{
    $blSuccess = FALSE;
    clearstatcache();
    if (is_readable($strFile) && !is_dir($strFile)) {
        if(@unlink($strFile)) {
            $blSuccess = TRUE;
        }
    }
    return $blSuccess;
}

When you use the is_dir() and is_readable() functions the results are cached for faster future use which is why I use the clearstatcach(0 function to ensure that the checks are current. Prefixing the unlink() function call with "@" suppresses the warnings and notices should any be generated.
