если у вас есть массив, используйте эту функцию в PHP

        function addOCheckBoxValuesByArray($arr) {      
                foreach ($arr as $key => $value) {
                echo"<input type= 'checkbox' name='formBylist[]' value='$value' />$value<br />";
                }

        }



    below code access data after user press submit button

    if(isset($_POST['formBylist']))
        {   
            $selectedDataBylist = $_POST['formBylist'];
            if(!isset($selectedDataBylist))
            {  // is data not selected
                echo "You didn't select data from below checkbox Table";
            }
            else
            { // data is user selected
                $Cnt = count($selectedDataBylist);

                for($i=0; $i < $Cnt; $i++)
                {           
                $result =$selectedDataBylist[$i]);

                    }
    }
    enter code here

}



to put all check boxes in scroll bar - use CSS 

<html lang="en">
<head>
<style>
.container { border:2px solid #ccc; width:400px; height: 500px; overflow-y: scroll; } 
</style>
</head>



///
<form action="<?php echo htmlentities($_SERVER['PHP_SELF']); ?>" method="post">         
                <div class="container">             
                                   addOCheckBoxValuesByArray($chekboxarray);?>
                </div>
