PHP memcached会话无法正常工作

I started to use memcached for storing session files, but Session doesn't work and apache sends response too slow. How can I solve the problem?

Modifications in php.in are:

;session.save_handler = files
session.save_handler = memcached
session.save_path = "tcp://127.0.0.1:11211?persistent=1&weight=1&timeout=1&retry_interval=15"

I solved the problem, Solution is connection url without tcp:// ,so session.save_path should be

session.save_path = "127.0.0.1:11211?persistent=1&weight=1&timeout=1&retry_interval=15"

read this page:
http://www.php.net/manual/en/memcached.sessions.php
you should modify php.ini like that

session.save_handler = memcached 


Change memcached to memcache
Maybe Helpful for you
Else
That Check For Server Permissions And Check For Charset of Your PHP script And
Put this code:
in being:

<?php
ob_start ();
?>


at the end:

<?php
ob_flush ();
?>
