Sql insert id from one table to entry in another

I have two tables in my database. When I insert record to first table I need to take id that automatically generate by Mysql and add it to a new record in 2nd table.

So I need to take id from this record:

$sql = "INSERT INTO movies (title, year, format);

and put it inside this record:

$sql = "INSERT INTO actors(name, last_name, movi_id);
-----------------------------------------------^
                                              HERE

Use below in-built PHP function for getting id from your last Insert Query:

mysqli_insert_id();

Your code must be like below to resolve your issue:

$sql = "INSERT INTO movies (title, year, format) VALUES ($title, $year, 
$format)";    
$movi_id = mysqli_insert_id();
$sql = "INSERT INTO actors(name, last_name, movi_id) VALUES ($name, 
$last_name, $movi_id)";

It's better if you can write above query in Prepared Statements to make it more secure:

// prepare and bind Movies Query
$queryMovies = $conn->prepare("INSERT INTO movies (title, year, format) 
VALUES (?, ?, ?)");
$queryMovies->bind_param("sss", $title, $year, $format);

// execute Movies Query
$queryMovies->execute();

// Get last inserted Id of Movies Query
$movi_id = $queryMovies->insert_id;

// prepare and bind Actors Query
$queryActors = $conn->prepare("INSERT INTO actors (name, last_name, movi_id) 
VALUES (?, ?, ?)");
$queryActors->bind_param("sss", $name, $last_name, $movi_id);

// execute Actors Query
$queryActors->execute();

// Close Connections
$queryMovies->close();
$queryActors->close();
