Here is my code

$array1 = array('royalty', 'free', 'picture');

for ($i=0; $i < count($array1); $i++) { 
$array2 = array(
    array('Affordable and search from millions of royalty free'),
    array('from millions of royalty picture'),
    array('Provides free picture upload and hosting'),
    array('Post your picture here Get permanent links picture'),
    array('Choose your own unique username to access image')
);

foreach($array2 as &$item) {
    $item = count(array_intersect(explode(' ', $array1[$i]), explode(' ', $item[0])));
}

print_r($array2); }

Answer 1

Change the array order cause intersect return all array from the first array. Check the below code i have modified. It may helps. Thanks

   $array1 = array('royalty', 'free', 'picture');

   for ($i=0; $i < count($array1); $i++) { 
   $array2 = array(
   array('Affordable and search from millions of royalty free'),
   array('from millions of royalty picture'),
   array('Provides free picture upload and hosting'),
   array('Post your picture here Get permanent links picture picture'),
   array('Choose your own unique username to access image')
  );

  foreach($array2 as &$item) {
      $item = count(array_intersect(explode(' ', $item[0]), explode(' ',     $array1[$i])));
  }

print_r($array2);

I have modified here

**$item = count(array_intersect(explode(' ', $item[0]), explode(' ',     $array1[$i])));**

Thanks,
