如何用PHP删除指定目录下的所有文件?
答
http://us.php.net/manual/en/function.unlink.php。 你会发现在评论中许多功能,包括做什么,你需要
一个例子:
function unlinkRecursive($dir, $deleteRootToo)
{
if(!$dh = @opendir($dir))
{
return;
}
while (false !== ($obj = readdir($dh)))
{
if($obj == '.' || $obj == '..')
{
continue;
}
if ([email protected]($dir . '/' . $obj))
{
unlinkRecursive($dir.'/'.$obj, true);
}
}
closedir($dh);
if ($deleteRootToo)
{
@rmdir($dir);
}
return;
}
答
$dir = '/some/path/to/delete/';//note the trailing slashes
$dh = opendir($dir);
while($file = readdir($dh))
{
if(!is_dir($file))
{
@unlink($dir.$file);
}
}
closedir($dh);

此功能将递归删除(如rm -r
)。小心!
function rm_recursive($filepath)
{
if (is_dir($filepath) && !is_link($filepath))
{
if ($dh = opendir($filepath))
{
while (($sf = readdir($dh)) !== false)
{
if ($sf == '.' || $sf == '..')
{
continue;
}
if (!rm_recursive($filepath.'/'.$sf))
{
throw new Exception($filepath.'/'.$sf.' could not be deleted.');
}
}
closedir($dh);
}
return rmdir($filepath);
}
return unlink($filepath);
}
答
function Delete($path)
{
if (is_dir($path) === true)
{
$files = array_diff(scandir($path), array('.', '..'));
foreach ($files as $file)
{
Delete(realpath($path) . '/' . $file);
}
return rmdir($path);
}
else if (is_file($path) === true)
{
return unlink($path);
}
return false;
}
这也将删除指定目录 – apelliciari 2009-12-17 09:15:08
