Is it possible to do something like this :

function __construct() { ... }
function __get($key)

return (isset($this->array[$key]) == false ? null : $this->array[$key]);
}
function __set($key, $value) { $this->array[$key] = $value; } }
$foo = new foo();
if (isset($foo->bar) == false) $foo->bar = 'bar'; else echo $foo->bar;
It seems that isset($foo->bar) return ALWAYS false. Bug ?
Fred.
It seems that you are right. I've tried off this code:
<?php
class OO
{
private $elem = array("a" => 1);
public function __get ($prop)
{
if (isset($this->elem[$prop])) {
return $this->elem[$prop];
} else {
return NULL;
}
}
public function __set ($prop, $val)
{
$this->elem[$prop] = $val;
}
}
$o = new OO();
echo isset($o->a) ? "yes\n" : "no\n"; echo isset($o->b) ? "yes\n" : "no\n";
echo is_null($o->a) ? "yes\n" : "no\n"; echo is_null($o->b) ? "yes\n" : "no\n";
?>
I expected something like this:
yes no no yes
But got this:
no no no yes
It looks like isset() can't handle object properties correctly. I'll post the bug on php.net.
