xattr_remove — Remove an extended attribute
Description
bool xattr_remove
( string $filename
, string $name
[, 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.
Parameters
- filename
-
The file from which we remove the attribute.
- name
-
The name of the attribute to remove.
- flags
-
Supported xattr flags XATTR_DONTFOLLOW Do not follow the symbolic link but operate on symbolic link itself. XATTR_ROOT Set attribute in root (trusted) namespace. Requires root privileges.
Return Values
Returns TRUE on success or FALSE on failure.
