[FX.php List] Random Image

[DC]

forget calculating a number and then parsing the array.
just use PHP's array_rand() to get a record key and use that.

this code is tested.

<?php

// mock up array like FX.php data
$searchResult['data'] = array(
'1.1' => array('fieldname' => array('data1')),
'2.2' => array('fieldname' => array('data2')),
'3.3' => array('fieldname' => array('data3')) );

echo '<pre>';
print_r(($searchResult['data']));
$rand_key = array_rand($searchResult['data']);
//print_r($rand_key);
print_r('RANDOM value from fieldname:');
print_r($searchResult['data'][$rand_key]['fieldname'][0]);
echo '</pre>';


?>
