$internal_links=array();

I prefer to init arrays, it also avoids unnecessary notices, and sometimes
weird results, but either one of those while loops should make the desired
array

while($row = mysql_fetch_array($result, MYSQL_ASSOC))
 { array_push($internal_links, array('phrase'=>$row['phrase'],
'link'=>$row['link'])); }
or

while($row = mysql_fetch_array($result, MYSQL_ASSOC))  { $internal_links[] =
array('phrase'=>$row['phrase'], 'link'=>$row['link']); }

or

while($row = mysql_fetch_object($result))  { $internal_links[] =
array('phrase'=>$row->phrase,
'link'=>$row->link); }

(you can figure out how to do it with array_push if you choose to, but you
get the general idea)
