PHP - Using Count With Where
Hello, I'm using the following code to count the amount of SQL results and divide it. Works great as is but I want to alter it so it works with categories.
$amount = mysql_query('SELECT COUNT(`car_id`) AS num FROM `tbl_cars`') or die(mysql_error()); $amount_row = mysql_fetch_assoc($amount); I tried adding... WHERE car_cat = '".$cat."' which causes an error. Why doesn't this work, and how can I get the amount of results as a variable? Similar TutorialsHi guys, I need your help.

But i am not getting how eactly i can get this.

Thanks! hey i'm just woundering how i would go abouts on echoing unread messages sent to a user i want to beable to see how many unread messages i have $count=0; $numb=50; foreach ($sepkeys as $dbkey) { for ($page=10;$page<=$numb;$page=$page + 10) { // the if block $count=$count+1; } } I am trying to maintain a separate a count for each key number in the above code. Eg: key- 574, it searches from pages 10-50 and increments the count by 1. The problem that I have is the count is continuous. After searching for the first key and moves on to the next key and them I need the count to start from the beginning rather than being continuous. Eg: key-874 : count = 22, in my case the next key 875 : the count is 23 I need to make it 1. I removed the if block and several lines because the code is too long.

Hi, I want the user to be able to go to one page and hit a button, once he hits the butten I want a count down to start from 10 minutes. When the user goes to the page within those 10 minutes, I want it to show him a live countdown until those ten minutes run out. Any ideas how I would go about doing this?

Thanks in advanced.
I did find this counter that works but the numbers appear 0.0.1 if counting up. I don't want to confuse the user. I really want to display to the user how long they was on a certain page.
