Bug description:__set() ignores setting properties with empty names
Description:
------------
Within only __set(), you can set a value of a new property with an empty
name ($p = null; $this->$p = 1;). The property won't really be created
though - the effects will be invisible to the user. No errors, warnings,
or notices are generated. This lack of an error message might cause
difficult to pinpoint bugs since all assignments of previously undeclared
properties within object scope regardless of originating method are routed
through __set();
Elsewhere in the object, attempting this will cause a fatal 'Cannot access
empty property' error as expected.
Test script:
---------------
<?php
class A{
function __set($prop, $val) {
echo "SET $prop = $val\n";
$this->$prop = $val; // should've caused error
}
}
$a = new A();
$prop = null;
$a->$prop = 2;
print_r($a); // empty object
?>
Expected result:
----------------
fatal 'Cannot set empty property' or 'invalid property name' error.
Actual result:
--------------
Nothing.
