了解准备好的语句以防止SQL注入 – Jens

首先，您的代码对SQL注入开放，所以您可能试图执行该SQL语句中的任何内容。这导致了这一点...当查询失败时，查询是什么？什么是MySQL的错误？你目前没有检查这些东西。 – David

只是字段名称和使用破灭功能，而将数据做成了。

例如：

$data['name'] = 'abc'; 
    $data['description'] = 'description'; 
    $data['created'] = date("Y-m-d H:i:s");

查询：

 $fields = array_keys($data); 
     $sql = "INSERT INTO table_name . (`" . implode('`,`', $fields) . "`) 
       VALUES('" . implode("','", $data) . "')";

试试这个：

$qry = "INSERT INTO `pr`(`pur`, `empid`, `appb`, `expdate`, `appn`, `specification`, `qty`, `esp`) VALUES "; 
$i = 0; 
foreach($qty as $a => $b) {     

    $qry .= "('$pur[$a]','$empid[$a]','$appb[$a]','$expdate[$a]','$appn[$a]','$specification[$a]','$qty[$a]','$esp[$a]')"; 
    if($i == count($qty)) { 
     $qry .= ";"; 
    } else { 
     $qry .= ","; 
    } 

$i++; 
} 

$result = mysqli_query($mysqli, $qry);

如果您有大量的数据，然后使用插入查询一次，它会提高效率。
