Implementing a simple lookup table with PHP -


i find myself needing simple php lookup table don't want bother using database.

for instance, might have:

1 stands "good" 2 stands "bad" 3 stands "ugly"

two ways implemented shown below. 1 more efficient other? there other more intuitive ways implement this?

switch($code) {     case 1:$result="good";break;     case 2:$result="bad";break;     case 3:$result="ugly";break;     default:$result=null; }  $array=array(1=>"good",2=>"bad",3=>"ugly"); $result=$array[$code];

it's matter of going lookup.

  • if it's lookup of key -> value pairs - array way go
  • if want perform different actions based on key - it's use case strategy pattern - no case or array way @ all.

so, case option inferior in cases, less scalable , not able change in run time.

to simulate default case, use like

$result = in_array($key, $lookup) ? $lookup[$key] : $default;

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
