set javascript variable to a php variable that has the name of a js variable [closed]

So I got 4 php variables, and I have 1 javascript variable with the name of one of those 4 php variables, how can I call it.

$p1 = ...
$p2 = ...
$p3 = ...
$p4 = ...
<script>
    var myoption = 'p1';
    var myarray = <?= $p1 ?>;
    console.log(myarray);
</script>

In this case instead of setting myarray to $p1, I want to do it with myoption, once myoption can be p2 or p3
