Variables

[The Hobo]

I'm pretty sure someone has asked this before, but lets say I have this:

$title = "My Title";

if ($action == 'view') {
  view();
elseif ($action == 'show') {
  show();
}

function view() {
  echo $title;
}

function show() {
  echo $title;
} 

Nothing shows up?

variables in functions are considered local to that function, they do not have global scope

you can do this to overcome it, or use the global keyword at the top of the script to change the behaviour

$title = "My Title";

if ($action == 'view') {
  view($title);
elseif ($action == 'show') {
  show($title);
}

function view($title) {
  echo $title;
}

function show($title) {
  echo $title;
}

Or you can make the variable global:

$title = "My Title";

if ($action == 'view') {
  view();
elseif ($action == 'show') {
  show();
}

function view() {
  global $title;
  echo $title;
}

function show() {
  global $title;
  echo $title;
}
