I'm trying to use the following statement to insert photograph information into photograph table:

$stmt = $mysqli->prepare("INSERT INTO Photographs(Genre, Name, Photographer, Camera, location) VALUES(?,?,?,?,?)");
$stmt->bind_param('isiis', $genre, $name, $photographer, $camera, $location);

After successful insert I would like to get the auto incremented primary key value of the photograph table and insert into a junction table (for my many to many relationship) as such:

$stmtPhotoGenre = $mysqli->prepare("INSERT INTO PhotoGenre(idPhotograph, Genre) VALUES(?,?)");
$stmtPhotoGenre->bind_param('ii', $idPhotograph);

Is there a way to get the id of the last insert using MySQL or PHP? I thought of using timestamp but there is always a chance that two people can be inserting at the same time and some sort cross mapping could happen. Any solution or suggestions?

    You can get it back using this class variable named mysqli_insert_id.

    It looks like all you have to do is access $stmtPhotoGenre->insert_id;, or run mysqli_insert_id($link); if you're not going the OOP route.

    I think the MySQL LAST_INSERT_ID function will meet your needs.
