              	foreach($datesquerysss as $task){

            ]
        })
    });

how to parse in json

Answer 1

Horses mixed up in a bunch, people ...
In the controller, iterate over the array into a new structure that matches the required format, such as:

$events = [
  'events' => [
    ['title' => '...', 'start ' => '...'],
    ['title' => '...', 'start ' => '...'],
    ['title' => '...', 'start ' => '...'],
    ['title' => '...', 'start ' => '...'],
  ]
];

in the view, pass the result through json_encode, you get:

{
  "events": [
    {
      "title": "...",
      "start ": "..."
    },
    {
      "title": "...",
      "start ": "..."
    },
    {
      "title": "...",
      "start ": "..."
    },
    {
      "title": "...",
      "start ": "..."
    }
  ]
}

and output with echo or the appropriate construct of your template engine:

var caledarEvents = <?php echo json_encode($events); ?>;
$(document).ready(function() {
        $('#calendar').fullCalendar(caledarEvents)
});

I think you should start learning from the basics.
You have mixed everything together. First, for some reason, you convert a string to Json, then you try to parse it in a loop ...
If you need data from php to javascript, then you can do this, for example:
index.html

<?php
    $datesquerysss = ....
?>
<script>
   var jsonstring = ' <?php  echo json_encode($datesquerysss);  ?> ';
    ...... 
    var jsonobject =  JSON.parse(jsonstring );
   console.log(jsonobject);
</script>

In json, you can not convert at all, but immediately collect the js object.
