Answer 1

SELECT
  table1.movie_title AS movie_title,
  GROUP_CONCAT(table2.genre_title) AS genre_titles
FROM
  table3
INNER JOIN
  table1
  ON table1.movie_id = table3.movie_id
INNER JOIN
  table2
  ON table2.genre_id = table3.genre_id

Results:

title_movie_1 | title_genre_1,title_genre_2
title_movie_2 | title_genre_1,title_genre_3
title_movie_3 | title_genre_1,title_genre_2,title_genre_3

Php code :

<?php
// Make a MySQL Connection
mysql_connect("server", "user", "password") or die(mysql_error());
mysql_select_db("db") or die(mysql_error());

$result = mysql_query("SELECT ... FROM ...") 
or die(mysql_error());  

// keeps getting the next row until there are no more to get
while($row = mysql_fetch_array( $result )) {
  echo "Movie: " + $row['movie_title'];
  echo "Genre: " + $row['genres_title'];
} 

?>
