php怎麼增加多行數據

php增加多行資料的方法：1、建立一個PHP範例檔案；2、連接資料庫；3、透過mysqli_multi_query()函數執行多條SQL語句並使用INSERT語句向資料表增加多行數據即可。

本文操作環境：windows7系統、PHP7.1版、DELL G3電腦

php怎麼增加多行資料？

mysqli_multi_query() 函數可用於執行多條SQL語句。

以下實例為"MyGuests" 表新增了三個新的記錄:

實例(MySQLi - 物件導向)

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
 
// 创建链接
$conn = new mysqli($servername, $username, $password, $dbname);
// 检查链接
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
} 
 
$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES (&#39;John&#39;, &#39;Doe&#39;, &#39;john@example.com&#39;);";
$sql .= "INSERT INTO MyGuests (firstname, lastname, email)
VALUES (&#39;Mary&#39;, &#39;Moe&#39;, &#39;mary@example.com&#39;);";
$sql .= "INSERT INTO MyGuests (firstname, lastname, email)
VALUES (&#39;Julie&#39;, &#39;Dooley&#39;, &#39;julie@example.com&#39;)";
 
if ($conn->multi_query($sql) === TRUE) {
    echo "新记录插入成功";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}
 
$conn->close();
?>

Note 請注意，每個SQL語句必須使用分號隔開。

實例 (MySQLi - 面向過程)

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
 
// 创建链接
$conn = mysqli_connect($servername, $username, $password, $dbname);
// 检查链接
if (!$conn) {
    die("连接失败: " . mysqli_connect_error());
}
 
$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES (&#39;John&#39;, &#39;Doe&#39;, &#39;john@example.com&#39;);";
$sql .= "INSERT INTO MyGuests (firstname, lastname, email)
VALUES (&#39;Mary&#39;, &#39;Moe&#39;, &#39;mary@example.com&#39;);";
$sql .= "INSERT INTO MyGuests (firstname, lastname, email)
VALUES (&#39;Julie&#39;, &#39;Dooley&#39;, &#39;julie@example.com&#39;)";
 
if (mysqli_multi_query($conn, $sql)) {
    echo "新记录插入成功";
} else {
    echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}
 
mysqli_close($conn);
?>
