pass php variable to select the right option

I'm trying to select the option based on the php variable value. So I need option value=1 is selected in the first <select> and option value=6 selected in second . Since I have a bunch of other <select> in the form, eventually, I will have an php array of some values, and I need each of the value match up with the option value under corresponding index in the a group of <select> that sharing the same class='si_1', and assign selected to that option.

Thanks

php part

<?php 
$select_1 = "1";
$select_2 = "6";
?>

JQuery part

$(document).ready(function(){
    var sel_class = $(".si_1");
    var array = {"<?php echo $select_1?>","<?php echo $select_2?>"};
    JQuery.each(array, function(index, value) {
        var current = sel_class.get(index);
        $(current + " option[value=" + value + "]").attr('selected', 'selected');
    });
});

I don't know if $(current + " option[value=" + value + "]") is the correct syntax to target the <select> at index in $(".si_1") that has option where the option attribute value has value that's at index in array

HTML part

<select class="si_1">
    <option value="1">Test 1</option>
    <option value="3">Test 3</option>
    <option value="5">Test 5</option>
    <option value="7">Test 7</option>
</select>
<select class="si_1">
    <option value="2">Test 2</option>
    <option value="4">Test 4</option>
    <option value="6">Test 6</option>
    <option value="8">Test 8</option>
</select>

You can do this in the JavaScript:

selectedVal1 = "<?= $select_1; ?>";
selectedVal2 = "<?= $select_2; ?>";

When the client looks at it, it will look like this:

selectedVal1 = "1";
selectedVal2 = "6";

Then it's just using jQuery to set the selected attribute to selected (Just do .attr('selected', 'selected'))
