xattr_remove — Remove an extended attribute
Description
bool xattr_remove
( string $filename
, string $name

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.

- flags

Return Values
