{
if (file_exists($dir))
{
if(!is_dir($dir))
exit("{$dir}不是一个目录");
else
{
$dirObj = dir($dir);
while ($file = $dirObj->read())
{
if (is_dir($dir .'http://www.jb51.net/'. $file) && $file !== '.' && $file !== '..')
{
clearDir($dir .'http://www.jb51.net/'. $file);
if (@!rmdir($dir .'http://www.jb51.net/'. $file))
echo "没有权限删除{$dir}/{$file}目录
";
}
elseif ($file !== '.' && $file !== '..')
{
if (unlink($dir .'http://www.jb51.net/'. $file))
echo "{$file}文件成功删除
";
}
}
}
}
else
exit("{$dir}不存在");
}
clearDir('./demo');
