Question

I need to know the time since a table in my MySQL database was edited. Is there any way to do this in PHP? The only way I can think of is to get the update time, and compare it to the current time (which will be a little bothersome).

Answer 1

One solution would be to add a timestamp field, that is automatically updated whenever a row is changed.
Then you can find the last change time by selecting the last update value:

# Add a timestamp column:
ALTER TABLE [TABLENAME] add column `ts_update` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP;

# Get the last update value:
SELECT MAX(ts_update) from [TABLENAME];
