Declare a global object and add to it

[timgerr]

Here is my problem, I am used to different languages (java,flex) where I can declare somthing and then add to it when I want. Here is my problem, I want to declare an object, run a function that will add an array to the object and then add to that object from another function. It might be easier to show you what I am trying to say:

global $test;
 $test = new stdClass;
 $test->name = 'Master';
 function AddTest()
 {
 	$arr = array();
	$a = new stdClass;
	$a->name = 'Tom';
	$arr[] = $a;
	$test->children = $arr;
 }
 
 AddTest();
 print_r($test);

This outputs

stdClass Object ( [name] => Master )

I want it to output

stdClass Object ( [name] => Master, [children] => Array ( [0] => stdClass Object ( [name] => Tom)))

Can I create a global something to add to it whenever I want?

Thanks for the read and help,

the global keyword is a bit of a misnomer. it bring a global variable available in the local scope, it can also make a variable that exists only in the local scope, variable. read up in the manual.

it's usage is from inside areas of local scope, however. you cannot use global from the global scope.

so to access $test from your Addtest() function you must use the global keyword from within the function.

 //global $test;
 $test = new stdClass;
 $test->name = 'Master';
 function AddTest(){
    [red]global $test;[/red]
    $arr = array();
    $a = new stdClass;
    $a->name = 'Tom';
    $arr[] = $a;
    $test->children = $arr;
 }
 
 AddTest();
 print_r($test);

the alternative is to use the $GLOBALS array which will contain references to all the variables in the global scope.
