Answer 1

Try with this:
function getWord($words){
$association = array();
foreach($words as $word)
{
$query = mysql_query("SELECT typewords FROM words WHERE word = '$word' ");
if($row = mysql_fetch_array($query))
$association[$word] = $row['typewords'];
elseif(preg_match('/[\.\,\:\;\?\!]/',$word)==1)
$association[$word] = $word;
}
return $association;
}
$typewords = getWord($b);
foreach($b as $w)
echo $w.'/'.$typewords[$w];

Answer 2

function getWord($word){
// concat the word your searching for with the result
// http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_concat
$query = mysql_query("SELECT CONCAT(word,'/',typewords) as this_result FROM words WHERE word = '$word' ");
$row = mysql_fetch_array($query);
return $row['this_result']." "; // added a space at the end.
}
// loop through the $b array and send each to the function
foreach($b as $searchword) {
echo getWord($searchword);
}

You assume the function parameter to be an array, but it is a string.
Edit: In your function you treat $word as an array as well as a string. Decide what you want and recode your function.
