What Does Insert Multiple Records Mean in PHP MySQL?

Inserting multiple records means adding more than one row into a MySQL table using a single or multiple SQL queries.

There are two common approaches:

• Multi-row INSERT query
• Loop-based INSERT using PHP

Prerequisites for Inserting Multiple Records

Before starting, ensure you have:

• PHP installed
• MySQL database created
• A working MySQL database connection
• A table with appropriate columns

---

Sample MySQL Table Used in Examples

CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(100),
    email VARCHAR(100),
    age INT
);

PHP MySQL Database Connection Code

<?php
$conn = mysqli_connect("localhost", "root", "", "testdb");

if (!$conn) {
    die("Database connection failed");
}
?>

---

Insert Multiple Records Using Single SQL Query

<?php
$query = "INSERT INTO users (name, email, age) VALUES
('Rahul', 'rahul@example.com', 25),
('Amit', 'amit@gmail.com', 30),
('Neha', 'neha@gmail.com', 22)";

if (mysqli_query($conn, $query)) {
    echo "Multiple records inserted successfully";
}
?>

Output:

Multiple records inserted successfully

This method is fast and efficient when data is static.

Insert Multiple Records Using PHP Loop

<?php
$users = [
    ['Suresh', 'suresh@gmail.com', 28],
    ['Pooja', 'pooja@gmail.com', 24],
    ['Ravi', 'ravi@gmail.com', 31]
];

foreach ($users as $user) {
    $query = "INSERT INTO users (name, email, age)
              VALUES ('$user[0]', '$user[1]', $user[2])";
    mysqli_query($conn, $query);
}

echo "Records inserted using loop";
?>

Output:

Records inserted using loop

---

Insert Multiple Form Records Using PHP

This method is useful when submitting dynamic form data.

<?php
$names = $_POST['name'];
$emails = $_POST['email'];
$ages = $_POST['age'];

for ($i = 0; $i < count($names); $i++) {
    $query = "INSERT INTO users (name, email, age)
              VALUES ('$names[$i]', '$emails[$i]', $ages[$i])";
    mysqli_query($conn, $query);
}

echo "Form records inserted";
?>

Output:

Form records inserted

---

Secure Insert Multiple Records Using Prepared Statements

Prepared statements are recommended for security.

<?php
$stmt = mysqli_prepare($conn,
    "INSERT INTO users (name, email, age) VALUES (?, ?, ?)");

mysqli_stmt_bind_param($stmt, "ssi", $name, $email, $age);

$records = [
    ['Anil', 'anil@gmail.com', 29],
    ['Kiran', 'kiran@gmail.com', 26]
];

foreach ($records as $rec) {
    $name = $rec[0];
    $email = $rec[1];
    $age = $rec[2];
    mysqli_stmt_execute($stmt);
}

echo "Multiple records inserted securely";
?>

Output:

Multiple records inserted securely

---

Insert Multiple Records Using MySQL Transaction

Transactions ensure data consistency.

<?php
mysqli_begin_transaction($conn);

try {
    mysqli_query($conn, "INSERT INTO users (name, email, age)
                         VALUES ('User1','u1@gmail.com',20)");
    mysqli_query($conn, "INSERT INTO users (name, email, age)
                         VALUES ('User2','u2@gmail.com',22)");

    mysqli_commit($conn);
    echo "Transaction completed successfully";
} catch (Exception $e) {
    mysqli_rollback($conn);
    echo "Transaction failed";
}
?>

Output:

Transaction completed successfully
