Hey there

Im working on a script right now and to make it more effecient im going to need to use a " For() loop with a counter"

Can someone supply just the base code of a for loop with a counter that i can work off =)

Thanks

   echo $i . "

}

 

Outputs

//Your starting number & Ending number
$start_point = 0;
$end_pont = 5;


for($i = $start_point; $i < $end_point; $i++) 
//What we do here is the following:
// $i = $start_point == your starting number
// $i = $end_point == your ending number
// $i++ == counts to that number to stop


//Start the loop
{

//echo out your restult
echo $i.'
';


//close the loop
}

 

Hope thats a good description to help you.

Yeah thanks alot.

Basically i have a query selecting 3 ids from a table in the DB. Now i need to select those 3 IDs and send 3 different numbers to that users account. So i figured if i used a for() loop with a counter that would be the best way to do it?

I think a while function would be best.

 

//Your ids bellow
$array = array(1,2,3);

//Fetch rows
$row = mysql_query("SELECT userid FROM users WHERE userid=1 AND userid=2 AND userid=3");

//Count / leave
$i = -1;

//fetch $row values
while($soc = mysql_fetch_assoc($row))

//open loop
{
//random number
$rand = rand(1,10);

//count up
$i++

//Event user with random number
event_add($soc[$array[$i]],"Random Number: ".$rand.".");

//if $i = 3 exit script and cloose loop
if($i == 2)
{
	exit;
}

//End loop
}

 

That should help i hope. :lol:

Re: Need base code to work off.

Hmmmm, i dont think that will do it. Im selecting three IDs from a table that i have. A userid is in each ID (Not selecting from the users table)

Then once they are selected im sending three differents precentages of money out of a total lot. The reason i need the loop is obviously for looping the Event ad and the update money etc and i thought the counter for the different percentages being sent which is why i came to the conclusion of a for() loops witha counter, lol...

Ill contact you on msn.

A while function can do that for you.
