How to save multiple checkboxes values in different rows of database

I am working on a checkbox table, the submitted data should be saved in the mysql database. There are two columns in the table, auto-increment Id and another one for saving the values of the checkbox.

Currently it is only saving one value at a time even when I select multiple, only the latest one gets saved. Here's the code:

report.php

<?php


$active = "report";
require_once 'pages/header.php';
require_once './functions/schema-functions.php';

$course = Schema::getCourse();
$objective = Schema::getObjective();
?>




<form id="addReport" action ='./functions/report-functions.php' method="post">

<table id="table1" class="table">
    <?php
    echo '<tr><th>Objectives</th>';
    for ($i = 0; $i < count($course); $i++) {
        echo '<th id = "rotate1">'. $course[$i]->commonName . '</th>';            
    }
    echo '</tr>';

    for ($y = 0; $y < count($objective); $y++) {
        echo '<tr><th class=row-header>'.$objective[$y]->objective.'</th>';

    for ($x = 0; $x < count($course); $x++) {

        echo "<td><input name='check[]' type=checkbox value=c".$course[$x]->courseId."-o".$objective[$y]->objectiveId." id=checked></td>";

        }
        echo '</tr>';
    }
    ?>

</table>
<input type="submit" name= "submit" value= "Submit"/>

report-functions.php

<?php


 require_once 'db-connect.php';

if(isset($_POST['submit'])){
{


$conn = DatabaseConnection::getConnection();
    $conn->beginTransaction();
    if(isset($_POST['check'])){
   foreach($_POST['check'] as $value){
    $sql = $conn->prepare("INSERT INTO Report (ColRow) VALUES 
 ('$value')");
  }
    if ($sql->execute(array( ':checked' => $checked))) {
        $conn->commit();
        return true;
    } else {
        $conn->rollback();
        return false;
    }

   }
   }
   }
    ?>

I want to save multiple selected checkboxes in different rows of the database and after submit, I want to display the table again with the boxes being checked and the user should be able to make the checks and submit the data again.

For saving the records, you might try like this:

<?php

    if( isset( $_POST['submit'], $_POST['check'] ) ){
        try{

            require_once 'db-connect.php';
            $conn = DatabaseConnection::getConnection();


            $sql='insert into `report`  ( `colrow` ) values ( :value )';
            $stmt = $conn->prepare( $sql );



            if( $stmt ){

                $conn->beginTransaction();

                foreach( $_POST['check'] as $index => $value ) {
                    $result = $stmt->execute( [ ':value' => $value ] );
                    if( !$result ) {
                        throw new Exception( sprintf( 'Failed to execute query %d for %s', $index, $value ) );
                    }
                }

                $conn->commit();
                exit();
            }
        }catch( Exception $e ){
            $conn->rollback();
            exit( $e->getMessage() );
        }
    }
?>
