Redis replaces php file storage session

: This article describes how to replace the PHP file storage session in redis. For more information about PHP tutorials, see. Before viewing an instance, please first understand the usage of the PHP session_set_save_handler function

Define a SessionManager class
Class SessionManager {
Private $ redis;
Public function _ construct (){
$ This-> redis = new Redis ();
$ This-> redis-> connect ('192. 168.0.102 ', 192 );
$ Retval = session_set_save_handler (
Array ($ this, "open "),
Array ($ this, "close "),
Array ($ this, "read "),
Array ($ this, "write "),
Array ($ this, "destroy "),
Array ($ this, "gc ")
);
Session_start ();
}
Public function open ($ path, $ name ){
Return true;
}
Public function close (){
Return true;
}
Public function read ($ id ){
$ Session_value = $ this-> redis-> get ($ id );
If ($ session_value ){
Return $ session_value;
} Else {
Return "";
}
}
Public function write ($ id, $ data ){
If ($ this-> redis-> set ($ id, $ data )){
Return true;
} Else {
Return false;
}
}
Public function destroy ($ id ){
If ($ this-> redis-> delete ($ id )){
Return true;
} Else {
Return false;
}
}
Public function gc ($ maxlifetime ){
Return true;
}
Public function _ destruct (){
Session_write_close ();
}
}

The code for creating a session_set.php is as follows:

Include ("SessionManager. php ");
New SessionManager ();
$ _ SESSION ['User _ name'] = "xxdcsnd@sina.com ";

The code for creating a session_set.php is as follows:

Include ("SessionManager. php ");
New SessionManager ();
Echo $ _ SESSION ['User _ name'];

Test output result xxdcsnd@sina.com

Note: php. ini session. save-hadler is set to user, otherwise session_set_save_handler will not take effect

The above introduces the replacement of PHP file storage session in redis, including the content, hope to be helpful to friends interested in PHP tutorials.
