posting updated date

is there a php code that posts the date that the database was last updated?

Are you asking about any row in the database being updated, or a single row in the table being updated? (The answer is no on the second option-- you must add a timestamp column to your table(s) to track the last update; there may be a way to do it on the first option)

Also it helps to provide basic info such as the database you are using (i.e. MySQL).

to clarify i am using a mysql database and i want the time to be updated every time there is a row added to one of the tables.

also is there a page that fully explains the different types of fields in a database?

A time updated that any row is updated? Well, instead of making a separate table for the status of the last update, you can query the table with the rows sorted descending on the date column and use the latest insert/update date. Not too difficult. e.g.

SELECT * FROM news ORDER BY updateTime DESC LIMIT 1

And use updateTime as the "latest update"

oh well i don't want to change the order i want there to be a thing that says table last updated: and has the date that the most recent row was added

It doesn't change the order. It's the order it retrieves the data in this particular query.

SELECT updateTime FROM news ORDER BY updateTime DESC LIMIT 1

Will select the time of the latest updated row if your column for updated time is updateTime.

<?php $query="SELECT updateTime FROM members ORDER BY updateTime DESC LIMIT 1" echo $updateTime ?>

I'm extremely new to php and thats the code i put on the site but its not working

I assumed you knew how to use MySQL databases with PHP.
