i have a movie table and i want to compare the common movies of two users.
$array1=array();
$array2=array();
$query2="select name from movie where user_id='1'";
$result2=mysql_query($query2) or die(mysql_error());
while($rss = mysql_fetch_assoc ($result2))
{
$array1[]=$rss;
}
print_r($array1);
This will print
Array ( [0] => Array ( [name] => Snatch ) [1] => Array ( [name] => The Social Network Movie )<br />[2] => Array ( [name] => Death Note ) [3] => Array ( [name] => Titanic ) <br />[4] => Array ( [name] => Once Upon a Time in the West ) )
And for second user
$query3="select name from movie where user_id=1";
$result3= mysql_query($query3) or die(mysql_error());
while($rss1= mysql_fetch_assoc($result3))
{
$array2[]=$rss1;
}
print_r($array2);
This will print
Array ( [0] => Array ( [name] => The Lord of the Rings Trilogy ) [1] => Array ( [name] => Snatch ) <br />[2] => Array ( [name] => The Social Network Movie ) [3] => Array ( [name] => Scarface ) <br />[4] => Array ( [name] => Once Upon a Time in the West ) [5] => Array ( [name] => Legend of the Guardians: The Owls of Ga'Hoole ) [6] => Array ( [name] => Once Upon a Time in America ) <br />[7] => Array ( [name] => Butch Cassidy and the Sundance Kid ) [8] => Array ( [name] => Fracture ) <br />[9] => Array ( [name] => Invictus ) [10] => Array ( [name] => Pride and Glory ) [11] => Array ( [name] => Casablanca ) )
When i compare these two arrays it gives me the first array.
$match= array_intersect($array1, $array2);
print_r($match);
The result will is
Array ( [0] => Array ( [name] => Snatch ) [1] => Array ( [name] => The Social Network Movie )<br />[2] => Array ( [name] => Death Note ) [3] => Array ( [name] => Titanic ) <br />[4] => Array ( [name] => Once Upon a Time in the West ) )
But the Common movies are:
Snatch , The social network movie , once upon a time in the west
