PHP chooses the side the cube has?
The php section of my code does not perform the correct operations when the user submits his number, for example, if the user submits 5, I want the rand function to randomly output 5 as the selected number; however my code sometimes works and other times doesn't.

<body>
<h1>Choose a die number</h1>
<form method = "post" action="choosedie.php"/>
<!--If the user selects a number of sides the die is suppose to have
rand should go through and pick the number randomly, and echo out the
number that was entered by the user-->
Please choose how many sides a die should have from 1 through 6:
<br/>
<input type = "text" name = "roll"/>
<?php
//Roll a random dice from 1 through 6:
$roll = rand(1,6);
// Add random variable to do comparison on.
Is there a way for me to just compare rand here without creating another variable?
$random = rand(1,6);
// If $roll is equal to $random echo the output out to the user.
If ($roll == $random)
{
echo "<br/>Here is the random $roll with the appropriate maximum value $random\n";
If the user selects 5, I want this to come out of 5, but I get different values?
}
?>

I think what you are trying to do here is to ask the user to enter the number of sides that the stamp has and then output the value? The question doesn't make a lot of sense ... but if above you are trying this, this should work:
choosedie.php
<h1>Choose a die number</h1>
<form method = "post" action="choosedie.php"/>
Please choose how many sides a die should have from 1 through 6:
<br/>
<input type="text" name="roll"/>
<input type="submit" value="Submit" />
</form>
<?php
if (isset($_POST["roll"])) {
$roll = rand(1, $_POST["roll"]);
printf("A %s was rolled, with a maximum roll of %s", $roll, $_POST["roll"]);
}
?>
This will allow the user to enter the number of sides that the stamp has and then print what has been unfolded along with the number of sides.

I'm not sure what you are trying to do. Each time this page loads, it will pick two random numbers, $ random and $ roll, and if they are equal, print them.
If you want users to enter data, you need to use $ _POST.
$users_dice_roll = $_POST["roll"];
$random_dice_roll = rand(1,6);
if($random_dice_roll == $users_dice_roll){
echo "You rolled: $users_guess";
}
Also, don't you need a submit button?
