Hi everybody, For the last few days I have been reading about Etags. In some articles they highly recommend to use Etags but in some not. So I am confused and I'll ask for your help. First, I'm using Apache server and for now one server is enough to serve my content. I've already using expire headers for images, css and js files. So my question is, should I remove Etags or configure it properly so that it works with expire headers properly? And if I'm gonna use it how do I configure it? From htaccess or from php? Cause in Yslow it says I have x misconfigured Etags. Thanks,

thanks for quick response.. How can we show the numbers day by day in the last week for example?

hello everyone, In my script, when a user registers I use a datetime field in db (mysql) to store registration date&time of users. What I want to do is, for my statistics module I want to show daily members count for a time period..for example, date1 - x users date2 - y users date3 - z users ... whats the best way to do this? Thanks

Sorry, my mistake that I forget the last parentheses. actually what I want to do is to combine if blocks. example; $class = ($lastNotified < strtotime($timeAdded)) ?'undread':''; $class .= ($i == $count)?' last':''; echo '<li'.(!empty($class))?' class="$class"':''.'>'.$row['message'].'</li>'; but, since I've been working with more than one class I couldn't make it work. any suggestions? thank you

how can i rewrite the code below in a more proffessional way. I mean avoiding repetation, using ternary operator in one line or at least two. if (($lastNotified) < strtotime($timeAdded) { if ($i == $count) { echo '<li class="unread last">'.$row['message'].'</li>'; } else { echo '<li class="unread">'.$row['message'].'</li>'; } } else { if ($i == $count) { echo '<li class="last">'.$row['message'].'</li>'; } else { echo '<li>'.$row['message'].'</li>'; } }

Hello, In a web project, let's say we have a thousand users. In our algorithm, first we randomly determine a lucky user and we want to notify other users how close they're to the lucky user. Example, user_id 365 -> lucky user my user_id 360 and in my page it should say 5 user away from the lucky user.. We cannot determine it using user_id cause there may be some irregularities due to the deleted user rows. Any suggestions on how to determine the difference between lucky user and others. Thanks
