php怎么样变量到一定时间清理？php中session定期自动清理的方法

配置完成php后默认php会将session生成到/tmp目录下，导致/tmp目录文件很多，因此需要对session进行定期的清理。

修改php.ini：

代码如下

复制代码

[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 will clear php session before 3 hours.

i="0 1 2 3 4 5 6 7 8 9 a b c d e f"

forbyrd in$i;

forx in$i;

mkdir-p /tmp/session/$byrd/$x;

done;

done

chown-R bywww:bywww /tmp/session

chmod-R 1777 /tmp/session

find /tmp/session -amin +180 -execrm -rf {} ＼;

if[ `grep'session.save_path ='/usr/local/php/lib/php.ini | wc -l` -eq 3 ];then

sed -i's#;session.save_path = "/tmp"#;session.save_path = "/tmp"＼nsession.save_path = "2;/tmp/session"#g'/usr/local/php/lib/php.ini

else

exit1

定时任务：

[root@hz scripts]#echo'#This is a config php session BY:BYRD AT:2015-11-12'>>/var/spool/cron/root

[root@hz scripts]#echoƆ 3 * * 0 /bin/bash /byrd/scripts/spehspsion.sh >/dev/null 2>&1'>>/var/spool/cron/root
