因此，这是用于邮寄用激活邮件注册唯一用户名密码的用户。现在我生成一个随机数，我将该特定的随机数存储在用户的数据库中，并且数据库中还有一个激活字段，它可以是0或1（对于未激活或未激活）。现在当用户登录时，我们检查激活字段，如果没问题，我们继续，否则我们检查url的$ _GET [激活]字段，如果它与存储在数据库中的随机数匹配，则继续返回激活错误。现在是我们如何做到这一点或有其他方式。另外我如何删除一段时间后未激活的账户。通过邮件激活用户账户

我不会用rand（）创建激活密钥。有可能两个人获得相同的号码。

所以我总是使用SHA1（）与用户名和当前时间。

对于灭活的账户的自动删除：

可以创建一个cronjob自动检查登记时间和当前时间之间的差。

SHA1（）做什么？以及cronjob做什么，在我如何实现它？ – Kraken

SHA1（）从字符串创建一个散列，请参阅http://php.net/manual/function.sha1.php。使用cronjob脚本会自动在特定的时间段之间调用。也许你的提供者提供类似的东西，但也有很多其他的免费系统。 – ComFreek

是SHA和SHA1一样吗？ – Kraken

user603003权说，cron的，用来执行调度操作简单的Linux程序，我个人用它来删除会话文件。如何使用cron

Here is the format of a cron job file: 

[min] [hour] [day of month] [month] [day of week] [program to be run] 

where each field is defined as 
[min] Minutes that program should be executed on. 0-59. Do not set as * or the program will be run once a minute. 
[hour] Hour that program should be executed on. 0-23. * for every hour. 
[day of month] Day of the month that process should be executed on. 1-31. * for every day. 
[month] Month that program whould be executed on. 1-12 * for every month. 
[day of week] Day of the week. 0-6 where Sunday = 0, Monday = 1, ...., Saturday = 6. * for every day of the week. 
[program] Program to be executed. Include full path information. 

Here are some examples: 

0,15,30,45 * * * * /usr/bin/foo 

Will run /usr/bin/foo every 15 minutes on every hour, day-of-month, month, and day-of-week. In other words, it will run every 15 minutes for as long as the machine it running.
