How to show checkboxes as checked when values are set in the database in codeigniter

i use foreach for show data came form database.

This is for Plan_data

<?php foreach ($veddingPlanData as $row) { ?>

<input box with value containing "echo row->value_name" >

<?php  }  ?>

THis is for task data as check box [hear i want to show the checkbox list in which the task is given to plan_id they appear as cheeked chekbox and remaining list with not checked status)

<?php foreach ($veddingPlanTaskMappingData as $row) { ?>
<input type="checkbox" name="task_id[]" value="<?php echo $row->task_id ;?>" checked><?php echo $row->task_name?><br>
<?php } ?>  

Hear i show the whole task list in check box.

<?php foreach ($allVedingTasks as $row) { ?>
<input type="checkbox" name="task_id" value="<?php echo $row->task_id ;?>" ><?php echo $row->task_name?><br>
<?php } ?>  

i want to foreach the task_name list with selected some task as there mapped plan_id.
