second, time stamp
1.strtotime Parse the datetime description of any English text into a Unix timestamp
Format: int strtotime (string time[,inttime[,intnow])
The first parameter of Strtotime can be our common English time format, such as "2008-8-20" or "Ten September 2000" and so on. It can also be a time description based on the parameter now, such as "+1 Day" and so on.
One, gets the UNIX timestamp for the specified date
Strtotime ("2009-1-22") examples are as follows:
1.echo strtotime ("2009-1-22")
Results: 1232553600
Description: Return January 22, 2009 0:0 0 seconds timestamp
Second, get the English text date time
1. Get the relevant timestamp for a few days ago or a few days + or-' Day ' or ' Day '
Strtotime ("+10 days")
2. Get a few weeks ago or a few weeks after the time + or-' Week ' or ' weeks '
Strtotime ("+10 Week")
3. Get a time stamp for a specified number of days and hours of the week
Strtotime ("+1 Week 2 days 4 hours 2 seconds");
4. Get timestamp for last Monday or next Thursday
Strtotime ("Last Monday")
Strtotime ("next Thursday")
5 getting timestamps a few years ago or years later
Strtotime ("+3 Years")
6. Get the first day of next month
Date (' Y-m-1 ', Strtotime (' +1 month '))
7. Get the last day of the month
Idea: The first day of next month, minus one day
Tmp=date (' Y−m−1′,strtotime (' +1month′)); Vardump (Date (' Y−m−d′,strtotime ') (Tmp=date (' y−m−1′,strtotime '); Vardump (Date (' Y−m−d′,strtotime (tmp. '-1 day '));
