<?php
class OO
{
private $array = array();
function __construct() {}
function __set($name, $value)
{
$this->array[$name] = $value;
}
function __get($name)
{
if (isset($this->array[$name]) == true)
return null;
else
return $this->array[$name];
}
}
$o = new oo();
$o->foo = 'bar';
echo (isset($o->foo) == true ? 'foo is set' : 'foo is not set');
#Expecting result
# => foo is set
#Real result
# => foo is not set
?>
If PHP provide __set() and __get() function in order to create property
dynamicaly, PHP function like isset() MUST BE USED with these "dynamic"
properties as usual.
So, in my example, isset() MUST return TRUE !! and not FALSE !!

This works fine for me:
[EMAIL PROTECTED]:~$ cat bug29917.php
<?php
class oo {
var $a;
}
$o = new oo;
echo isset($o->a) ? "yes\n" : "no\n";
$o->a = 'bar';
echo isset($o->a) ? "yes\n" : "no\n";
?>
[EMAIL PROTECTED]:~$ php bug29917.php
no
yes
Come up with a short example like mine that shows that it doesn't work.
Just saying $o->a won't work doesn't help.

Still not resolved, you still have to use the following code to access
the properties:
$a = $o->a;
echo isset($a) ? "yes\n" : "no\n";
Another guy thought that it would be neat if there was a __isset magic
method.

Sorry, but if you do that :
$o->a = 'foo';
echo isset($o->a) ? "yes\n" : "no\n";
Expected result was true, but actual result is false !
And $o->a is set !

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
This is correct, the isset() checks if a variable is set or not. In
your case it\'s simply not set (it will be set after __get() is
executed on it once).
