(sorry for my English)
http://pecl.php.net/get/dio seems broken at the moment
to get dio extension follow these steps (steps 1.a and 1.b are equivalent):
1.a get source files using cvs (you may need cvsnt or similar):
(in shell run)
cvs -d :pserver:cvsread@cvs.php.net:/repository login
Password: phpfi
cvs -d :pserver:cvsread@cvs.php.net:/repository co pecl/dio
cd pecl/apc
-- or --
1.b manually download all files at http://cvs.php.net/cvs.php/pecl/dio clicking on the revision number link
move to the destination directory
2. (in shell run)
phpize (if the system is missing the 'phpize' command see http://php.mirrors.ilisys.com.au/manual/en/install.pecl.phpize.php)
./configure --enable-dio --with-php-config=/path/to/php-config (usually /usr/local/php/bin/php-config or /usr/bin/php-config)
make
make install (you need root/admin privilegies)

You can manually build the dio extension for your version of PHP, or install an older version of PHP that still bundled dio. It's not that hard to build it yourself, just a bit of a process, and it helps if you're on linux, and have a build environment... which I would assume you have if you are doing some kind of development that requires direct device I/O... Just get the dio source from the cvs repo, compile it, and then add the extension to your php configuration...

to use mandatory locking on a linux system, the filesystem has to be well prepared.
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/hda1 / ext3 errors=remount-ro,mand 0 1
/dev/hda2 none swap sw 0 0
proc /proc proc defaults 0 0
/dev/fd0 /floppy auto user,noauto 0 0
/dev/cdrom /cdrom iso9660 ro,user,noauto 0 0
For example here the ext3 partition has been prepared for mandatory locking. Otherwise no dio_function will work on the system.

IMPORTANT:
--enable-dio is NOT recognized as an option. After reporting a bug, i got following answer:
It is not bundled anymore. See http://pecl.php.net/dio to fetch the CVS version (being unmaintained, there is no release in pecl). Not a bug > bogus.
