New to PHP and just trying to understand a little code.

I hope I'm not annoying anyone or breaking the rules but I was wondering about this bit of code right here:

        " <?php

$people = Array(

Array('name' => 'Kalle', 'salt' => 856412),

Array('name' => 'Pierre', 'salt' => 215863)

);

for($i = 0; $i < sizeof($people); ++$i)

{

$people[$i]['salt'] = rand(000000, 999999);

}

?> "

 

Okay from what I can get from this $i will continue to increase and the code will execute until ..... this seems too random or me to realize the goal of this code.

It looks like all it is doing is changing the value of the salt key

<?php
// Populate $people with two arrays, each containing two entries.
// "name" and "salt"
$people = Array
          (
                Array('name' => 'Kalle', 'salt' => 856412),
                Array('name' => 'Pierre', 'salt' => 215863
          )
);

// for($i = 0; $i < the size of $people, which is two; add one to i)
for($i = 0; $i < sizeof($people); ++$i)
{
    // Assign a new value for "salt" on this array item.
    $people[$i]['salt'] = rand(000000, 999999);
}

?>

That cleared things up thanks a lot guys. PHP is a lot of fun. I started off on HTML but it was good and simple but for some reason I thought something was missing. Now that I have moved on to PHP I realized that it was control that creates all the fun. Hope to talk to you guys soon.
