Calling functions from external class within functions

[birdzhavefangs]

So I'm having trouble getting a larger project to work- namely calling functions (from an outside class) within functions.  I'm sure this has been asked before, but I can't really think of a way to phrase it well enough for searching, so I apologize!

 

Here's my example:

First off is bob.php, the class file

<?php
class Bob {
   function loud( ) {
     echo "Bob\n";
   }
   function greet($name) {
     echo "Hello, ".$name."!\n";
   }
}
?>

 

And second is bobuser.php, that requires bob:

<?php
require_once("bob.php");
$B = new Bob;
$B->loud();
function bob2(){
 $B->loud();
}
bob2();
echo "oh noes";
?>

 

The output I want is:

Bob

Bob

oh noes!

 

Versus the output I'm getting is:

Bob

 

I'm working on large project right now, and I don't want to post it's code (due to mess, and laaarge size), hence the very simple example.  Thank you for your attention!

$B does not exist within your bob2 function, you will need to pass it in as an argument.

 

<?php
require_once("bob.php");
$B = new Bob;
$B->loud();
function bob2(Bob $obj) {
   $obj->loud();
}
bob2($B);
echo "oh noes";
?>

Thanks thorpe! 

I got it to work! Although, declaring with ($obj) instead of (Bob $obj)

function bob2($obj) {
   $obj->loud();
}

[trq]

function bob2(Bob $obj) {

 

would force $obj to be of type Bob which is in this case what you want.
