如何使用PHP將多維數組存儲到mysql中

Question

我創建了一個名為“test”的數據庫，並創建了一個名為“biodata”的表。 我在biodata表中創建了名為“Name”“Age”和“Description”的3列。 現在如何將我的數組結果存儲到每一列。

以下是完整的代碼......

<?php

    $ip = "localhost";
    $username = "root";
    $password = "";
    $dbname = "test";
    $res = mysql_connect($ip,$username,$password);
    if(!$res)
    {
        echo "DB Connection Failed.";
        exit;
    }
    if(!mysql_select_db("test"))
    {
        echo "NOT SELECTED";
        exit;
    }

        $company =  array(
                    'Record1'=>array('Shabbir',26,'Designer'),
                    'Record2'=>array('Burhan',24,'Architecture'),
                    'Record3'=>array('Huzeifa',20,'Accountant'),
                );

        foreach ($company as $employees=>$details){

        echo '<strong>'.$employees.'</strong><br>';

        foreach($details as $employeeinfo){

            echo $employeeinfo.'<br>';

        }

        }

        $sql = "INSERT INTO biodata (Name, Age, Description) VALUES ($employeeinfo[0], $employeeinfo[1], '$employeeinfo[2]')";
        mysql_query($sql);

?>

Answer 1

您的mysql_query假設在您的foreach語句中...您還需要因SQL Injection而清理數據

你也不需要2個foreach聲明......

更正

foreach ($company as $employees =>$details){
    echo '<strong>'.$employees.' - OK</strong><br>';
    mysql_query(sprintf($sql,mysql_real_escape_string($details[0]),mysql_real_escape_string($details[1]),mysql_real_escape_string($details[2])));
}

全文安排

$ip = "localhost";
$username = "root";
$password = "";
$dbname = "test";
$res = mysql_connect($ip,$username,$password);
$sql = "INSERT INTO biodata (Name, Age, Description) VALUES ('%s', '%d', '%s')";
$company =  array(
        'Record1'=>array('Shabbir',26,'Designer'),
        'Record2'=>array('Burhan',24,'Architecture'),
        'Record3'=>array('Huzeifa',20,'Accountant'),
);

if(!$res)
{
    echo "DB Connection Failed.";
    exit;
}

if(!mysql_select_db("test"))
{
    echo "NOT SELECTED";
    exit;
}

foreach ($company as $employees =>$details){
    echo '<strong>'.$employees.' - OK</strong><br>';
    mysql_query(sprintf($sql,mysql_real_escape_string($details[0]),mysql_real_escape_string($details[1]),mysql_real_escape_string($details[2])));
}

Answer 2

旁注。 無論循環有多小（迭代次數少）都不要在其中放置查詢。 而是僅使用循環來構造包含所有數據的一個復雜查詢，然后在循環外執行查詢。

編輯：您可以在循環中構造的查詢示例。

INSERT INTO table 
    (name, age, position)
VALUES
   ('Shabbir', 26, 'Designer'),
   ('Burhan', 24, 'Architecture'),
   ('Huzeifa', 20, 'Accountant');

Answer 3

你的SQL查詢只是在錯誤的地方：

foreach ($company as $employees=>$details)
{
    echo '<strong>'.$employees.'</strong><br>';
        foreach($details as $employeeinfo)
        {
            echo $employeeinfo.'<br>';
        }
    $sql = "INSERT INTO biodata (Name, Age, Description) VALUES ($details[0], $details[1], '$details[2]')";
    mysql_query($sql);
}
