PHP PDO
Introduction
The PDO (PHP Data Objects) extension allows developers to connect to numerous different types of databases and execute queries against them in a uniform, object oriented manner.
Syntax
PDO::LastInsertId()PDO::LastInsertId($columnName)// some drivers need the column name
Remarks
Warning
Do not miss to check for exceptions while using lastInsertId(). It can throw the following error:
SQLSTATE IM001 : Driver does not support this function
Here is how you should properly check for exceptions using this method :
// Retrieving the last inserted id
$id = null;
try {
$id = $pdo->lastInsertId(); // return value is an integer
}
catch( PDOException $e ) {
echo $e->getMessage();
}
