echoing array index and getting a blank page

[my8code]

<?

$array = array('eggs', 'bacon', 'football', 'baseball', 'ford', 'toyota'); 

$rand_index = mt_rand(0, count($array) / 2 - 1) * 2; 
?>



<?php echo "$array[$rand_index]"; ?><?php echo "$array[$rand_index+1]"; ?>

 

i dunno why this doesn't work. I want to echo both values three of the pairs such as eggs bacon  or football baseball

Use array_chunk and shuffle.

 

<?php

$array = array('eggs', 'bacon', 'football', 'baseball', 'ford', 'toyota');
$array = array_chunk($array, 2);
shuffle($array);

echo $array[0][0] . ' and ' . $array[0][1];
?>

Get rid of the double quotes in your echo statements.
