[SOLVED] array_intersec_assoc question, about what it does

[silverglade]

i was wondering if anyone could help me understand array_intersec_assoc. or what it does.

 

in my book it has

 

$array1 = array( "a" => "apple , "b" => "orange", "c" => "banana");
$array2 = array( "prune", "orange", "banana");
$simArray = array_intersect_assoc($array1,$array2);

 

it says in the book that $simArray will be  empty since none of the keys are the same. but im not sure what array_intersect_assoc does or what it is looking for in both arrays, what  conditions, and what it tries to put into $simArray. sorry if this is confusing. any help is greatly appreciated. thanks. derek

It returns an array with all of the key value combinations that are the same in two different arrays
