You should use $this->balance, not $this->$balance. The latter is equivalent to
$this->'', where all your values are being stored.
If possible, you might consider raising the error_reporting level in your php.ini

The following class definition lists three vars, yet they are all treated as one, as the call to
report() shows. I'd love to be able to define more vars in a class.
<?
class bankaccount {
var $balance;
var $transactions;
var $history;
function bankaccount () {
$this->$balance = 0.00;
$this->$transactions = 0;
$this->$history[$transactions] = $this->$balance;
}
function report () {
echo $this->$balance . "<br>";
echo $this->$transactions . "<br>";
echo $this->$history[$transactions] . "<br>";
}
function credit ($amount) {
$amount = abs($amount);
$this->$balance += $amount;
}
function debit ($amount) {
$amount = abs($amount);
$this->$balance -= $amount;
}
}
$USDaccount = new bankaccount;
$USDaccount->credit(10000);
$USDaccount->debit(1000);
$USDaccount->debit(.78);
$USDaccount->report();
?>
the result is:
8999.22
8999.22
8999.22
Why?
