Time (); Returns the current Unix timestampExample: $a =time (); Var_dump ($a); Output: Int (1392192781)2.strtotime (); resolve other formats to Unix timestamps Example: $b = Strtotime ("Now"); Var_dump ($b); Output: Int (1392192781) /* Format example in parentheses: ("Ten September 2000") ("+1 Day")Tomorrow ("+1 days")Tomorrow ("+1 Week") ("+1 Week 2 days 4 hours 2 seconds") ("Next Thursday")Next Tuesday ("Last Monday") ("2011-5-19 14:07"); */3.mktime (time [, minute [, Seconds [, Month [, Day [, Year]]]]); Can go beyond the natural range, such as 27 months, exceeding the high plus; returns false if the overall value is outside the computer's ability range.

second, return an array1.getdate (); timestamp (default today) returns an array. $today = getdate (); Var_dump ($today); /* Output array: Array (11) { ["Seconds"]=>int (32) ["Minutes"]=>int (27) ["Hours"]=>int (8) ["Mday"]=>int (12) ["Wday"]=>int (3) ["Mon"]=>int (2) ["Year"]=>int (2014) ["Yday"]=>int (42) ["Weekday"]=>string (9) "Wednesday" ["Month"]=>string (8) "February" [0]=>int (1392193652) } */

Iv. Modifying the default time zone1, repair php.ini configuration file: Date.timezone = etc/gmt+82, Date_default_timezone_set (); Sets the default time zone for all datetime functions in a script.such as: Date_default_timezone_set ("PRC"); China time zone.Another: Date_default_timezone_get (); Get Current time zone
So here's the question:
1. Ask for a time stamp of the morning?
2. What are the days of January 1 next year from today (early morning of the next day)?
