What are the potential errors or exceptions that can occur when trying to retrieve the last inserted ID value in PHP?

When trying to retrieve the last inserted ID value in PHP, potential errors or exceptions that can occur include not having a primary key defined on the table, the database connection not being established correctly, or the query not actually inserting a new record. To solve this, make sure that the table has a primary key defined, check the database connection, and verify that the insert query is successful before trying to retrieve the last inserted ID. 

// Assuming a successful database connection has been established

// Perform the insert query
$query = "INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2')";
$result = mysqli_query($connection, $query);

if($result){
    // Retrieve the last inserted ID
    $last_insert_id = mysqli_insert_id($connection);
    echo "Last inserted ID: " . $last_insert_id;
} else {
    echo "Error inserting record";
}
