The method of periodic automatic cleaning in PHP _php tips

The following is to introduce you to the PHP set session of the regular automatic cleaning example, because the session default is 15 minutes automatically to clear the variable to the memory, but some time does not take effect, the following we will take a look.

After the configuration completes PHP, the default PHP will generate session into/TMP directory, resulting in a lot of/tmp directory files, so the session needs to be regularly cleaned up.

Modify PHP.ini:

[Root@hz scripts]# grep "Session.save_path ="/usr/local/php/lib/php.ini;   Session.save_path = "N;/path"; Session.save_path = "N; Mode;/path "Session.save_path ="/tmp "Session.save_path =" 2;/tmp/session "[Root@hz ~]#, Cat/byrd/script/cleartmpsen.  SH #!/bin/bash # version:1.0 # author:byrd # Site:www.t4x.org # contact:root#t4x.org # This is script'll clear PHP 
Session before 3 hours.
