Convert the php timestamp to time

Time ();
Returns the current time, but returns an integer.

You can format it.
Date ("Y-m-d H: I: s", time ());
In this way, the connections are displayed in minutes.
Date ("Y-m-d", time (); year, month, and day only

For details, see hi.baidu.com/..9.html.

SQL statements also have time functions. You can check them here.

In js, convert a date to a timestamp, for example, 2013-08-30 to a timestamp.

I have encountered a timestamp issue before. In order not to be despised by everyone, let's talk about the concept first.

I don't know how to define the specific timestamp, but Baidu encyclopedia says, "The timestamp is the total number of seconds from January 1, January 1, 1970 (00:00:00 GMT) to the current time ".

According to this definition, there is a similar function in the programming language, getTime (), but this function returns the total number of milliseconds from January 1, January 1, 1970 to the current time, rather than the total number of seconds.

In js, converting a character to the Date type is not difficult:
Var str = '2017-08-30 '; // Date string

Str = str. replace (/-/g, '/'); // replace-with/, because the following constructor only supports date strings separated /.

Var date = new Date (str); // construct a date type data with the value of the input string

In the preceding section, the new Date (str) constructs a Date. The str parameter must provide at least three parts: year, month, and day, that is, the string in the form of "2013/03/08". It cannot be "2013/03 ", otherwise, a NaN is obtained. The constructed time is: 00:00:00. You can also specify the hour, minute, and second, but not the hour, for example, 2013/03/08 17. This parameter also produces a NaN. The parameter can be "17:20:05" or "" to get the correct time. If the number of seconds is not given, the default value is 0.

In this case, we get the date data. To get the so-called timestamp above, we can do this:
Var time = date. getTime ();
In this way, we get a value that represents the number of milliseconds from 00:00:00 on the first day of the month to the date. If we divide this number by 1000, we get the number of seconds. We also continue to divide it by 60 to get the minute, divide by 60 to get the hour and so on.

Tip: using this getTime () function, you can get the number of milliseconds of two dates and convert them into seconds, minutes, hours, or even days to compare the difference between the two dates.
