PHP MySQLi Get Last ID
PHP Tutorial » PHP MySQLi Get Last ID
How can I get the last insert / updated ID in PHP?
We have various methods for selecting the last insertion id from the MySQL table.
1. We can select a single row from the table in descending order and store the id.
2. Select Maximum value.
If we INSERT or UPDATE a row on a SQL table with AUTO_INCREMENT field, we can get the ID of the last inserted or updated record from table.
We have a table "Users" like the one below and we insert another row in it, then we get the last ID from DataBase.| ID | First Name | Last Name | UserName | |
|---|---|---|---|---|
| 1 | Clark | Kent | clarkkent | clarkkent@mail.com |
| 2 | John | Carter | johncarter | johncarter@mail.com |
| 3 | Peter | Parker | peterparker | peterparker@mail.com |
PHP Get Last ID - MySQLi (object oriented)
Before accessing data from the MySQL database, we must be able to connect to the server.
For this example we'll use the same Users table that we've created in the PHP MySQL create tables, which has three rows and five columns as: id, first_name, last_name, user_name and email, where id is the primary key column and marked with AUTO_INCREMENT flag.
<?php
$server_name = "localhost";
$user_name = "my_username";
$password = "my_password";
$db_name = "my_DB";
// Create connection
$link = new mysqli($server_name, $user_name,
$password, $db_name);// Check connection
if ($link->connect_error) {
die("Connection failed: " . $link->connect_error);
}
$sql = "INSERT INTO Users (first_name, last_name, user_name, email)
VALUES ('Stwart', 'Martin', 'StwartM', 'StwartM@agernic.com')";
if ($link->query($sql) === TRUE) {
$last_id = $link->insert_id;
echo "New record created successfully. Last inserted ID is: " . $last_id;;
} else {
echo "Error: " . $sql . "<br />" . $link->error;
}
$link->close();
?>
