[RESOLVED] Counting Output of Rand()

gsteak

Hi. I'm wondering how to count the output of rand().
Here's the layout for my code so far:

$flip=rand(0,1);

if $flip ==0
then heads

if $flip == 1
then tails

I need to then use a while loop to continue the rand function until there is 1 heads and 1 tails. How would I tell php to count this?

The Output must look like this:

Person: Heads, Tails
Person 1: 1, 9
Person 2: 2, 1
Person 3: 5, 1
....

etc.,

You can use sessions and count. like this:

<?PHP
session_start();


$flip = rand(0,1);


//bobs flipping a coin
if(isset($_POST['bob'])){

if($flip == '0'){
if (!isset($_SESSION['bobHeads']))
	$_SESSION['bobHeads']=1; else $_SESSION['bobHeads']++;
}elseif($flip  == '1'){
if (!isset($_SESSION['bobTails']))
	$_SESSION['bobTails']=1; else $_SESSION['bobTails']++;
}
}


//carls flipping a coin
if(isset($_POST['carl'])){


if($flip == '0'){
if (!isset($_SESSION['carlHeads']))
	$_SESSION['carlHeads']=1; else $_SESSION['carlHeads']++;
}elseif($flip  == '1'){
if (!isset($_SESSION['carlTails']))
	$_SESSION['carlTails']=1; else $_SESSION['carlTails']++;
}
}

?>

<html>
<body>
bob Heads:
<?php
echo ($_SESSION['bobHeads']);
?>
<br/>
bob Tails:
<?PHP
echo ($_SESSION['bobTails']);
?>
<form method="post" action="<?PHP $_SERVER['PHP_SELF']; ?>" >
<input type="submit" name="bob" value="bob">
</form>
<br/>
carl Heads:
<?php
echo ($_SESSION['carlHeads']);
?>
<br/>
carl Tails:
<?PHP
echo ($_SESSION['carlTails']);
?>
<form method="post" action="<?PHP $_SERVER['PHP_SELF']; ?>" >
<input type="submit" name="carl" value="carl">
</form>
</body>
</html>

hope that helps.

Thank you very much. I'll definitely look at your example as an alternative method, and edit my code accordingly.
I managed to solve it though. =] Thanks again for your quick response.

To be honest, based on what you wrote in your original post, I would not suggest sessions, since you stated nothing about persisting the state between page loads. All you need is two variables: one to store the count of heads, another to store the count of tails. An array could also suffice.
