php converts int type to time type

This project encountered the problem of timestamp conversion

The timestamp designed in the database is in int format, so certain conversion is required

$lasTtime=time();//这个是添加一个time时间戳

这个时间戳会输出当前时间并转换成int类型：1558321414  //这个是我写这个的时候的时间戳

When extracted You can use

$time=date("Y-m-d",$lastTime);//date是按你指定格式转换的函数

这个时间戳会变成：2019-05-20 11:03:34  //这个是我写这个的时候的时间戳

If you still want to convert 2019-05-20 11:03:34 into int format,

$lastTime=strtotime($time);//$time是你要转换的变量

will eventually become: 1558321414 / /This is the timestamp when I wrote this

If there is a time difference, you can use date_default_timezone_set("PRC"); to solve the 8-hour time difference problem

'Y-m-d H:i:s'
//这个是定义的时间格式
//需要什么取什么
//秒是s,分钟是i,小时是H,天是d,月是m,年是Y
echo date('i',$time_str);
//要与当前时间去计算的话不用转为时间型
$time_str = 1313994356;
c_time = time()-$time_str;
c_time得到的就是秒
//分钟的话除以60
c_time/60跟5去比较
