Php, date manipulation? -

I am new to php and i would like to know some date manipulation things in php.

  // Get current date $ date = date ("Y-M-D");  

What if I want to reduce the current date and a specific date, so says "today - 2008-06-26"?

If today, a customer accepts today's date 2009-06-26, after 1 week I Want to delete my account from my database, how do I do this? (I am using mysql)

What can we do if we store the user's date in our database? For example, we can store the date of the user's fleet, so when he sent some emails to him on his late day. What else can you do?

First of all, you need, and

returns the current timestamp (a int represents the current time and date).

, with no parameters, is similar to the parameters, this allows you to get the timestamp for a set time parameter is in this order: hour, minute , Seconds, month, day, year

Now, your question :

Question 1

To manipulate time, you can do the following:

  $ today = mktm (0,0,0); // today, neutral $ otherDate = mktime (0, 0, 6, 26, 2008); // 2008-06-26, Time Neutral $ sec Betterdates = $ Today- $ Other Date;  

Question 2

You are better than doing something directly in your SQL. Here are the ways you can do the two most common database servers running in PHP. I'm assuming that subscribed to date is a valid date in Datat.

  --- MySQL DELETE from 'Customer' Where Now () & lt; DATE_ADD (`Date Weekly ', Interval 1 week); --- Delete PostgreSQL from "Customers" Where CURRENT_TIMESTAMP & lt; ("Date subscribed" + Interval '1 week');  

Question 3

It depends on your DBMS. / html>
