Evaling anything makes a bit uncomfortable, but most especially
strings pulled out of the database. I typically use something like
this instead:

// db string is '%variable% word'
$db_string = str_replace('%variable%', $variable, $db_string);


If you have lots of things to replace, strtr() works well:

$vars = array(
  '%foo%' => $foo,
  '%bar%' => $baz,
  '%baz%' => $baz
);
$db_string = strtr($db_string, $vars);
