Question

Here’s the code

<?php
echo "<table border=\"0\">";
for ($d = 1; $d <= $times;$d++ )
 {
echo "<tr><td>";
echo  rand(1,6), "\n";
echo "</td></tr>";
} 
echo "</table>"; ?>

I’m trying to get the max,min and sum of the rand(1,6), "\n";
But i can’t figure it out. And it’s killing me.

You need to collect the random numbers in an array, too:

echo "<table border=\"0\">";
$rands = array();
#################
for ($d = 1; $d <= $times; $d++)
{
    echo "<tr><td>";
    echo $rands[] = rand(1,6), "\n"; 
         ###########
    echo "</td></tr>";
} 
echo "</table>"; ?>

Afterwards you can make use of max, min and array_sum (all these links come with nice examples).

As your code already shows you should start to differ between code that does data-processing and code that does the HTML output:

// handle the data

$randomNumbers = array();
foreach (range(1, $times) as $d)
{
    $randomNumbers[$d] = rand(1,6);
}


// output the data

echo '<table border="0">';
foreach ($randomNumbers as $number) {
    printf("<tr><td>%d</tr></td>", $number);
}
echo "</table>";
