xattr_remove — Remove an extended attribute
$filename

[, int $flags = 0
] )This function removes an extended attribute of a file.
Extended attributes have two different namespaces: user
and root. The user namespace is available to all users, while the root namespace
is available only to users with root privileges. xattr operates on the user
namespace by default, but this can be changed with the
flags parameter.
filename
The file from which we remove the attribute.
name
The name of the attribute to remove.
flags
XATTR_DONTFOLLOW |

Returns TRUE on success or FALSE on failure.
Example #1 Removes all extended attributes of a file
<?php
$file = 'some_file';
$attributes = xattr_list($file);
foreach ($attributes as $attr_name) {
xattr_remove($file, $attr_name);
}
