来自PHP数组的JS变量值不带整个数组值

I'm developing a holiday summer house rental website with a Jquery datepicker calendar that disables unavailable dates based on a MySQL query.

<?php
$datos = $con->query("SELECT * FROM bookings WHERE Status = 'Accepted' ");
?>

In order to calculate the disabled dates based on range of dates (checkin - checkout) I use a PHP code that calculates the dates in between and then puts those values in an array as follows:

<?php
while ($user = mysqli_fetch_array($datos)) {
    ?>
    <?php

// Declare two dates

    $Date1 = $user['Check_in'];
    $Date2 = $user['Check_out'];

// Declare an empty array

    $array = [];

// Use strtotime function

    $Variable1 = strtotime($Date1);
    $Variable2 = strtotime($Date2);

// Use for loop to store dates into array
    // 86400 sec = 24 hrs = 60*60*24 = 1 day

    for ($currentDate = $Variable1; $currentDate <= $Variable2;
        $currentDate += (86400)) {
        $Store   = date('Y-m-d', $currentDate);
        $array[] = $Store;}

// Display the dates in array format

    $finalvalue = $array;

// Write it to the output

    echo json_encode($finalvalue);?> <?php }?>

?>

$finalvalue outputs:

["2019-04-03","2019-04-04","2019-04-05","2019-04-06","2019-04-07", 
"2019-04-08","2019-04-09","2019-04-10","2019-04-11",  "2019-04-12","2019-04-13","2019-04-14"]   
["2019-04-24","2019-04-25"]

////// Now in my JS for the datepickers:

var disabledDates = <?=  json_encode($finalvalue)?>;
console.log(disabledDates)

////// for some reason finalvalue$ outputs only:

["2019-04-24","2019-04-25"] 

$("#checkin").datepicker({
    changeMonth: false,
    dateFormat: 'yy-mm-dd',
    defaultDate: new Date(),
    minDate: new Date(),
    beforeShowDay: function (date) {
        var string = jQuery.datepicker.formatDate('yy-mm-dd', date);
        return [disabledDates.indexOf(string) == -1]
    },
    prevText: '<i class="fa fa-chevron-left"></i>',
    nextText: '<i class="fa fa-chevron-right"></i>',
    onSelect: function (selected) {
        $("#checkout").val(selected);
        $("#checkout").datepicker("option", {minDate: new Date(selected)})
        calcDiff();
    }
});

Why isn't JS bringing the whole string of dates as in the PHP first output?

Could be that you are passing the variable in as a JSON encoded string but not parsing that data into a Javascript array? What if you did something like

var disabledDates = JSON.parse(<?= json_encode($finalvalue)?>);
