How to transfer time with php int?

php converts int type into time type

I encountered the problem of timestamp conversion during this project

Time of database design The stamp is in int format and requires certain conversion

$lasTtime=time();//这个是添加一个time时间戳

This timestamp will output the current time and convert it to int type: 1558321414 //This is the timestamp when I wrote this

When extracted, you can use

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

This timestamp will become: 2019-05-20 11:03:34 //This is the timestamp when I wrote this

　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

　It will finally 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
$time_str = 1313994356;
echo date('i',$time_str);//要与当前时间去计算的话不用转为时间型
$c_time = time()-$time_str;//$c_time得到的就是秒,分钟的话除以60,$c_time/60
