switch statement question

[netmastan]

Any request(ie.action=del) other then(action=file,action=index) should shows file not found.
How to do that.. here is my code..

switch ($_GET['action'])
{
case "file":
checkfile();
break;



default:
index();
break;
}

if u use session , do u have to start session in every function(ie.index()) as inside this function there will be html code.

Or just session start at the begining of php file ?

thanks

switch ($_GET['action'])
{
case "file":
checkfile();
break;
case "index":
index();
break;
default:
filenotfound();
break;
}

if you want to access session variables from session you retrieve it by doing thjis.

function some(){
global $var;
print $var;
}

thank you but I want to index() default.

you do that by placing the 'index' case smack up against the default case without any break...

switch( $action ) {
  ...
    case 'index':
    default:
        index();
}

you can double or put as many case'': together as you want, if it doesn't see a break; then it will just fall through to what is below
