Note: in javascript (for AJAX context), it would be new Date().getTime() but it's in milliseconds instead of seconds. In mysql, the queries handling that epoch time must use from_unixtime function and unix_timestamp, which are luckily in seconds like in PHP. Going via epoch timestamp is a requisite when you don't want to have to consider timezones and summer time shift. time() is a very necessary function that every languages should have an equivalent.

Thanks for the complement :) I hope I'll always be giving away some usable stuff, there are some even more beginner oriented things on the way too! Hi rruben!

Whether the PHP articles stay here or move somewhere else, I will probably be a regular reader if the tips stay as great as this one ;) Great post!
