如何回顯0，何時不勾選複選框？

當按下提交按鈕，它會回顯11 但我想回聲101（回聲0未檢查ckeckbox）。

我該怎麼做？

<form id="form02" name="form02" method="post"> 
    <input name="h_type[]" type="checkbox" id="h_type[]" value="0" checked/><input type="hidden" name="more[]" value="1"> <br/> 
    <input name="h_type[]" type="checkbox" id="h_type[]" value="1" /><input type="hidden" name="more[]" value="1"> <br/> 
    <input name="h_type[]" type="checkbox" id="h_type[]" value="2" checked/><input type="hidden" name="more[]" value="1"> <br/>  
    <input type="submit" name="button" id="button" value="Submit" /> 
</form> 


<?php 
$data_h_type=$_POST['h_type']; 
$data_more=$_POST['more']; 

if(count($data_h_type)>0){ 
    foreach($data_h_type as $key=>$value){ 
      echo $data_more[$value]; 
        echo "<br>"; 
    } 
} 

?>

echo isset($data_more[$value]) ? $data_more[$value] : 0;
