PDO get the last ID inserted php
In PHP with PDO and MySQL, you can retrieve the last inserted ID using the lastInsertId() method. This method returns the ID of the last inserted row in the database, which is often useful when dealing with auto-increment primary keys. Here's how you can use it:

php

// Assuming you have already established a PDO connection, you can use it to execute your query.

// Your SQL INSERT statement
$sql = "INSERT INTO your_table (column1, column2) VALUES (:value1, :value2)";

// Prepare the statement
$stmt = $pdo-prepare($sql);

// Bind parameters if needed
$stmt bindParam(':value1', $value1);
$stmt-bindParam(':value2', $value2);

// Execute the query
$stmt-execute();

// Get the last inserted ID
$lastInsertedID = $pdo-lastInsertId();

// Now you can use the $lastInsertedID as needed (e.g., to update related records or display the ID to the user).

Here's a breakdown of the code:

Replace your_table with the name of the table where you are inserting the data.
Replace column1 and column2 with the column names where you are inserting the values.
$value1 and $value2 are the actual values you want to insert into column1 and column2.
After executing the query with $stmt-execute(), you can use $pdo-lastInsertId() to retrieve the last inserted ID.

This method is reliable for obtaining the last inserted ID for the current connection. It is especially useful when working with auto-increment primary keys, as it ensures you get the correct ID even in multi-user scenarios.
