CLXXIII. xattr Functions

Введение

The xattr extension allows for the manipulation of extended attributes on a filesystem.

Требования

To use xattr, you will need libattr installed. It is available at http://oss.sgi.com/projects/xfs/.

Замечание: These functions only work on filesystems that support extended attributes, and have them enabled at mount time. Some common filesystems that support extended attributes are ext2, ext3, reiserfs, jfs, and xfs.

Установка

xattr is currently available through PECL http://pecl.php.net/package/xattr.

If PEAR is available on your *nix-like system you can use the pear installer to install the xattr extension, by the following command: pear -v install xattr.

You can always download the tar.gz package and install xattr by hand:

Пример 1. xattr install by hand

gunzip xattr-xxx.tgz
tar -xvf xattr-xxx.tar
cd xattr-xxx
phpize
./configure && make && make install
