Arrays in class

[zgstyle]

Please help!
I need to parse XML file and in script i have following piece of code:

class abc {
var $dum= array();
var $mas = array();

function set_data($varname,$dat) {
$this->$varname[] = $dat;
}
}
$temp = new abc();
$temp->set_data("mas","Hello");

print_r($temp->mas);

When i run thic code I get :
Fatal error: Cannot use [] for reading...

Is this a PHP bug or my mistake?

Try
{$this->$varname}[] = $dat;

Interesting. You are trying to pass the name of a member array variable and assign to it.

$this->$varname = $dat;
Works but of course it's not an array.
I tried various permutations using the $$ syntax as discussed in the manual but no joy. And I tried assorted {}.

We need a real guru to solve this one.

By the way, the var $mas = array() line is not really doing anything. You can only initialize stuff in a constructor.

first of all:
var $mas = array();

in the class does get initialised, when the new object is created i.e. in $temp = new abc;

the initial value of the var $mas is array(), no matter whether it was set in constructor or not.

coming to the point, you should be doing assorting like this:

$this->{$varname}[] = $dat;

which works.
