I didn't want to leave without trying to help. Perhaps a more foreach-friendly variant of
array_rand() could be useful:
function Select_Random_Indices($source_array, $count = 1)
{
if($count >= 0)
{
if($count == 1)
{
result = array(array_rand($source_array, $count));
}
else
{
result = array_rand($source_array, $count);
}
}
else
{
$result = array();
}
return $result;
}
Then you could do something like this:
function Select_Random_Entries($source_array, $count = 1)
{
$result = array();
$index_array = Select_Random_Indices($source_array, $count);
foreach($index_array as $index)
{
$result[] = $source_array[$index];
}
return $result;
}
