PDO get the last ID inserted
database, mysql, pdo, php
Solution
That's because that's an SQL function, not PHP. You can use `PDO::lastInsertId()`.
Like:
$stmt = $db->prepare("...");
$stmt->execute();
$id = $db->lastInsertId();
If you want to do it with SQL instead of the PDO API, you would do it like a normal select query:
$stmt = $db->query("SELECT LAST_INSERT_ID()");
$lastId = $stmt->fetchColumn();
Problem
I have a query, and I want to get the last ID inserted. The field ID is the primary key and auto incrementing. I know that I have to use this statement: ``` LAST_INSERT_ID() ``` That statement works with a query like this: ``` $query = "INSERT INTO `cell-place` (ID) VALUES (LAST_INSERT_ID())"; ``` But if I want to get the ID using this statement: ``` $ID = LAST_INSERT_ID(); ``` I get this error: ``` Fatal error: Call to undefined function LAST_INSERT_ID() ``` What am I doing wrong?
