如果使用php在数据库中，我如何检查复选框中的值 - How can i check the value in checkbox if its in database using php

How can i check the value in checkbox if its in database using php

如果值保存在数据库中，我会尝试选中复选框，但我根本不知道。

首先，我的复选框是关于尺寸的。超小型、小型、中型等

这是我显示尺寸和复选框的代码

$statement = $db->prepare("SELECT * FROM sizestops order by sizestopsID ASC");
$statement->execute();
while($rows = $statement->fetch(PDO::FETCH_ASSOC)) {
    $sizetopsCode = $row['sizetopsCode'];   
    echo "
        <label style='display: inline-block;
                font-size: 100%;
                font-family: Arial;
                width: 100px;'>
            <input type='checkbox' name='sizes[]' class='checkbox' id='sizesprod' onchange='checksize()' value='" .$rows['sizestopsID']. "'>" . $rows['sizetopsName'] ."</label>
            ";
    }

如何检查尺寸的值？请帮我T_T

<?
$statement = $db->prepare("SELECT * FROM sizestops ORDER BY sizestopsID ASC");
$statement->execute();
while($rows = $statement->fetch(PDO::FETCH_ASSOC)) 
{
    $sizetopsCode = $rows['sizetopsCode'];   
    $sizetopsID=$rows['sizestopsID'];
    $sizetopsName=$rows['sizetopsName'];
    ?>
    <label style='display: inline-block;font-size: 100%;font-family: Arial;width: 100px;'>
        <input type='checkbox' name='sizes[]' class='checkbox' id='sizesprod' onchange='checksize()' value="<? echo $sizetopsID;?>"><? echo $sizetopsName;?>
    </label>
