It looks like you need to call json_encode on $json['json'] before pass it to $a, You actually encode it AFTER you have passed the array to $a

<?php
    $i=0;
    $handle = fopen("./uploads/csv_temp.csv", "r");
    while (!feof($handle) ) {

        $line_of_text = fgetcsv($handle, 1024, ",");
        $json['json_'] = $line_of_text[0];
        **$a= json_encode($json['json_']);**
        echo $a;
    }
?>

<html>
<head></head>
<body>
    <script>
    var abc= " <?php echo $a; ?> ";
    </script>
</body>
</html>
