you can change this parameter to 1, so the probability is 100%.
See how the session works.
Overview: Every PHP request, a 1/100 probability (default) triggers a "session recycle". If "Session recycling" occurs, then the/tmp/sess_* file is checked, and if the last modification time is now more than 1440 seconds (gc_maxlifetime value), it is deleted, which means that the session expires.

/sess_* file is checked, and if the last modification time is now more than 1440 seconds (gc_maxlifetime value), it is deleted, which means that the session expires.
1. How does the session exist on the server side (typically Apache with PHP module)?
By default, PHP will save the session in the/tmp directory, the file name looks like this: sess_01aab840166fd1dc253e3b4a3f0b8381. Each of the files corresponds to a session.

and response time of SMTP mail servers.++++++++++++++ Availability RateAvailability is the percentage of the total time that a website or server can normally access.For example, the home page in a day can always be normal access, then the first page of the day's availability rate is 100%.If the home page has 9 minutes to access, and a total of 1440 minutes a day, then the first page availability rate is:((1440
Many people on the Web have given answers: Modify the Session.gc_maxlifetime in the PHP configuration file. If you want to learn more about the session recycling mechanism, continue reading. (This article Environment php5.2)

' process is started on every; Session initialization. The probability is calculated by using the following equation:; Gc_probability/gc_divisor. Where Session.gc_probability is the numerator and; Session.gc_divisor is the denominator in the equation. Setting this value to 1; When the Session.gc_divisor value was give you approximately a 1% chance; The GC would run on any give request. Increasing this value to the give you; A 0.1% chance the GC would run on any give request. For high volume pro
Under Windows or Linux, the default password for MySQL installation is empty.And when we've installed MySQL's management tools,phpMyAdmin after landing "Empty password login is prohibited (see allow password is null)". Cannot log on successfully

This article introduces the following, PHP set the session expiration method, introduced the more detailed, the need for friends, refer to it.The simplest way to set the session expiration in PHP is to modify the Session.gc_maxlifetime in the PHP configuration file.Overview: Every PHP request, a 1/100 probability (default) triggers a "session recycle". If "Session recycling" occurs, then the/tmp/sess_* file is checked, and if the last modification time is now more than
The default session validity period in PHP is 1440 seconds (24 minutes) [weiweiok note: the default value in php5 is 180 minutes]. That is to say, if the client does not refresh for more than 24 minutes, the current session will become invalid. Obviously, this cannot meet the needs.
The default session validity period in PHP is 1440 seconds (24 minutes) [weiweiok note: the default value in php5 is 180 minut
,Install all memcache instances.
We will not talk much about the applicability, because the three types of storage are files, databases, and memcache,It has a different scope of use, which requires personal experience.
Now let's talk about the program. In order to make it easier to use different storage mechanisms of this session, I made a session factory class to reduce coupling, so as to extend our futureThere will be great benefits.
