Help with Nightbot commands

You talk about the code to create a own command or one code to create a random answer command in nightbot.tv?

In php the code is:
<?php
$answers = array(
"Answer1",
"Answer2",
"Answer3",
"Answer4"
);
$random =
array rand($answer);
echo $answers[$random];
?>

After doing this, you upload the command to the Internet and make the next command in nightbot

!addcom ![command a name] $(urlfetch [URL of the command you uploaded to the internet])

I don't quite understand what a "the random viewer code" is. Depending on what type of random answers you want we can start to figure out where to start.

Hey @Sturdy Pig!

Please use the search bar, it's likely we already covered your question.

I'm thinking this could help, but without a clearer message, we can't help:
