comparing arrays

[Ustag]

Hello, I have a problem comparing arrays and printing them. My code looks soemthing like this:

$players_world = array();$players_world[] = $td->nodeValue; $players_guild = array();$players_guild[] = $td2->nodeValue; echo array_intersect($players_world, $players_guild);

This should print a number of names but I only get "Array", how come?

it sounds like the array_intersect() function is returning an array. try this to quickly see the values in the array:

$results = array_intersect($players_world, $players_guild);print_r($results);

edit: you cant just echo out the array you would need to specify which of the values in the array that you want to echo out. http://www.w3schools.com/php/php_arrays.asp

Thank you very much, my solution is this:

$compare_names = array_intersect($players_world, $players_guild);foreach($compare_names as $names_online)  {echo $names_online.'<br>';}
