So, the PHP website runs a lot of queries How do you tell which ones are specifically slowing down the server? (stats/analysis?)

Instead of doing this: if($action=="1" || $action=="2" || $action=="6" || $action=="99").. Can I do a shortcut? if($action==[2,6,3])) something like this?

For example. In my index.php, I have a simple text box. I put in a word, and click Submit. I want to have my C++ script analyze this word, and do some calculations. Then, I want to pass this back to my PHP, and spit out the length, etc. to the audience. The question is: How can I use both PHP and C++ to do things?? Thank you!

Multiple time zones...?

Hi, is there anyway to set limits within ONE select query? SELECT * FROM my_table WHERE (date = '123') <<< SET A LIMIT of 4 here. OR (name = 'sun') << SET A LIMIT of 3 here. I know that it's possible to break this into 2 SELECTS and UNION them. But is there a way to keep 1 query, and set limits between the "ORs"? thank you!

Hello, Does anybody know how to find the GET variable? www.domain.com?UNKOWN=255 Is there a way to figure out what Unknown is (using some method?) and also get the value? Thanks!

Well, even with this it doesn't really work: RewriteRule ^/([0-9a-z])$ /index.php?code=$1 [L]

What is the maximum size of php sessions? For example, this has been a really weird problem lately. I have a form which a user types a Question. This question is then stored in a Session. Then I Header("Location: ") To redirect to another page, then echo the Session. The weird thing is, sometimes, it works, sometimes it doesn't!! It's really really weird. If I click around my site (logged into my site), then it works. If I just enter my site and post the Question (logged in), it won't work.

What is that? I'm total noob about it. Can u explain more about it please? Thanks!

Hi, I'd like to know if anyone knows how to do this: Suppose I have a form where people submit stuff through a textbox. Each time they submit something, their score +1. Their timestamp is recorded. How can I make a list of "This week's top submitters"?

How do I order by relevance? Thanks
