Question

我想使用预处理语句向表中插入多行。为此，我使用循环从数组中提取数据并将其用于y语句参数，这是我的代码示例：

require_once("connect.php");
$data_array = Array();
$string = 'faycal,18,12,2016,podes|Arab,19,12,2016,kashi|faycal,20,12,2016,exec';
function create_array($input){
    $formated_array = explode('|', $input);
    $query = $con->prepare("INSERT INTO my_table (bill_name,bill_num,month,year,type) VALUES(?, ?, ?, ?, ?)");
        for ($i = 0;$i < count($formated_array);$i++){
            for($j = 0;$j < 5;$j++){
                $data_array[$i][$j] = explode(',', $formated_array[$i])[$j];
            }
            $query->bind_param($name, $num, $month, $year, $type);
            $name =  $data_array[$i][0];
            $num = (int)$data_array[$i][1];
            $month = (int)$data_array[$i][2];
            $year = (int)$data_array[$i][3];
            $type = $data_array[$i][4];

            $query->execute();
        }   
        echo "Records have been saved successfully";

}
create_array($string);

我在没有执行语句的情况下测试了这个函数并试图回显data_array，一切都运行得很好所以我假设我的SQL语句出了问题我无法理解进行。

SCOPE，范围，范围默认情况下，$con变量在函数内部不可见。 SO将其作为参数传递给函数

require_once("connect.php");
$data_array = Array();
$string = 'faycal,18,12,2016,podes|Arab,19,12,2016,kashi|faycal,20,12,2016,exec';

function create_array($con, $input){
    $formated_array = explode('|', $input);
    $query = $con->prepare("INSERT INTO my_table (bill_name,bill_num,month,year,type) VALUES(?, ?, ?, ?, ?)");
    for ($i = 0;$i < count($formated_array);$i++){
        for($j = 0;$j < 5;$j++){
            $data_array[$i][$j] = explode(',', $formated_array[$i])[$j];
        }
        $query->bind_param($name, $num, $month, $year, $type);
        $name =  $data_array[$i][0];
        $num = (int)$data_array[$i][1];
        $month = (int)$data_array[$i][2];
        $year = (int)$data_array[$i][3];
        $type = $data_array[$i][4];

        $query->execute();
    }   
    echo "Records have been saved successfully";
}

create_array($con, $string);

如何在FOR循环中多次执行准备好的SQL语句？
