How to get random value out of an array

I have code applying a random font to a div of text which is taken from the last 20 lines of a .txt file. I would like to apply a different random font to each line… any pointers?

<?php 

$fonts = array("Helvetica", "Arial", "Courier", "Georgia", "Serif", "Comic Sans", "Tahoma");
shuffle($fonts);
$randomFont = array_shift($fonts);

$output = "";
$lines = array_slice(file("users.txt"), -20, 20);

foreach ( $lines as $line )

{
$output .= '<div style="font-family:' . $randomFont . '; margin-left: ' . rand(0, 60) . '%; opacity: 0.8;">' . $line . '</div>';
}

echo $output;
?>

Live demo here.

The code:

$fonts = array("Helvetica", "Arial", "Courier", "Georgia", "Serif", "Comic Sans", "Tahoma");
shuffle($fonts);

$output = "";

$lines = array();
for($i = 0; $i < 40; $i++) $lines[] = "line $i";

$i = 0;
foreach ( $lines as $line ) {
  if($i == count($fonts)) {
    shuffle($fonts);
    $i = 0;
  }
  $output .= '<div style="font-family:' . $fonts[$i] . '; margin-left: ' . rand(0, 60) . '%; opacity: 0.8;">' . $line . "</div>\n";
  $i++;
}

echo $output;
