mysql - php while loop + where

list table

• id


• name


• illness


• recipe



• directions

  
  
  

  $illness = 'Highblood';
  $list = mysql_query("SELECT * FROM list ",$con);
  while($row=mysql_fetch_array($list, MYSQL_ASSOC)){
   $test[] = $row['recipe'];
  
   $test2[] = $row['directions'];
   }
  

I want to only get the rows

• $row['recipe'];


• $row['directions'];

if the value of illness column is equals to highblood.
how do I do this?
