PHP time function: php date, Time function

Date ("Y-m-d", Time ()) gets a string of times in a particular format. Time () is a timestamp value, or it can be omitted, the default current time. You can also fill in the value.
All functions in PHP are in the Unix era, starting January 1, 1970. The date is the number of seconds to start at this time. When a function call is counted as a number of seconds from this time, it is treated as a (timestamp) timestamp.
local time function
1. String date (string Format,inieger timestamp)
The function returns a string representing the time, which is controlled by the string format.
Such as:
?
Print (Date ("Y year M month D Day");//output current, Month day.
Print (Date ("Y year M month D Day", 60*60*24*365*10);//Output January 1, 1980.
?>
Perhaps you would ask, "How come there is no timestamp?" If timestamp is empty, or does not write, it indicates that the current time timestamp is used.
