Re: [PHP] Deleting Objects

Not exactly true.  unset() destroys the reference to the value, not the 
value itself.  For instance,

error_reporting(E_ALL);
$var1 = "foo";
$var2 = &$var1;
print "$var1\n$var2\n\n";
unset($var1);
print "$var1\n$var2";
will output:

foo
foo
<br />
<b>Notice</b>:  Undefined variable:  var1 in <b>PHPDocument1</b> on line 
<b>7</b><br />

foo

In other words, unsetting $var1 will NOT destroy $var2.
