數組中的字符串轉換錯誤

Question

我有一個查詢，它是回溯id的列表。這些ID在一個數組中，我需要使用這些ID將它保存在表中。我嘗試使用implode使這些id的字符串我可以在where子句中使用，但我不斷收到此錯誤。

$save_food = $_POST['save_food']; 
$unserializedData = array(); 
parse_str($save_food,$unserializedData); 
foreach($unserializedData as $unserializedData1){ 
$query = mysql_query("insert into subscribefood (s_user_id,s_food) values ('$ft_user_id','".implode($unserializedData1, ',')."')"); 
}

試試這個

<?php 
$save_food = $_POST['save_food']; 
$unserializedData = array(); 
parse_str($save_food,$unserializedData); 
$datalist = $unserializedData['foodtype']; 
foreach($datalist as $data){ 
$query = mysql_query("insert into subscribefood (s_user_id,s_food) values ('$ft_user_id','$data')"); 
} 
?>
