PHP uses Memcache to store session method Summary _php tutorial

Set session with Memcache to store

Method I: Global settings in php.ini
Session.save_handler = Memcache
Session.save_path = "tcp://127.0.0.1:11211"

Method II: In a directory. htaccess
Php_value Session.save_handler "Memcache"
Php_value Session.save_path "tcp://127.0.0.1:11211"

Method III: Again or in one application

< span="">< span="">("Session.save_handler", "Memcache"< span="">< span="">< span="">("Session.save_path", " tcp://127.0.0.1:11211 ");

Use multiple memcached servers separated by commas "," and, as described in the memcache::addserver () documentation, can take additional parameters "persistent", "weight", "timeout", "Retry_ Interval "And so on, like this:" Tcp://host1:port1?persistent=1&weight=2,tcp://host2:port2 ".

If the installed pecl is memcached (which relies on the extension of the libmemcached library), the configuration should be
PHP Code Collection Code
Ini_set ("Session.save_handler", "memcached"); It's memcached, not memcache.
Ini_set ("Session.save_path", "127.0.0.1:11211"); Don't tcp:[/b]

code example (the one that does not depend on the libmemcached library)

 
   < span="">< span="">< span=""> (! < span=""> (  < span="">  ['  test  ' [' test '] = < span=""> < span="">  < span=""> < span="">< span="">< span=""> < span="">< span=""> < /c26>< span="">    < span="">  < span="">  [' TEST3 '] =  < span="">  < span=""> [' < span=""> TEST '   < span="">  < span="">   < span="">   < span=""> < span=""> "

 < span="">  "  < span="">   [' < span=""> TEST3 '   < span="">   < span=""> < span=""> < span=""> "

"< span="">< span=""> < span=""> < span="">< span="">< /c72>< span="">  ?>

Use SessionID to go to memcached to check:

 
  Get (' 19216821213c65cedec65b0883238c278eeb573e077 ')); $memcache->set (' aaaa ', ' hello everyone '); Var_dump ($memcache->get (' aaaa '));?>

　　

'll see
String (PNS) "test|i:1177556731; test3|i:1177556881; "
This output proves that the session is working properly.
