comparing 2 arrays in a loop

[dsaba]

I have 2 arrays:

 

$array1[] = 'hello';

$array1[] = 'how';

$array1[] = 'are';

$array1[] = 'you';

$array1[] = 'bob';

 

$array2[] = 'hello how';

$array2[] = 'are you steve';

 

I want to compare $array1 with $array2, and if any value of $array1 is found in $array2 I want to perform an action

 

I know this has to be in a loop, i'm confused about how to set it up

it dose'nt need a loop.

 

$matches = array_intersect($array1,$array2);
if (count($matches) > 0)
{
// matches found so do you stuff.
print_r($matches); // print the matches just to check.
}
