Description:
------------
Currently when a an array/object is compared to a number (or string), PHP doesn't issue any E_NOTICE or E_STRICT, the comparison is done and the array/object is always greater (as documented in http://php.net/manual/en/language.operators.comparison.php).

I think that this 'feature' is detrimental to PHP and a source of confusion and waiting to happen catastrophes.

Reasons:
- 99.9% of such comparison are programming mistakes.
- There is no reason to expect objects or arrays to be always greater than _any_ number or string.
- The fact that no error at all is thrown when such comparison is performed is generally unexpected.

So I think that in future versions of PHP it would be nice if at least an E_STRICT was thrown.


Test script:
---------------
<?php

error_reporting(E_ALL | E_STRICT);

var_dump([7, 11] > 'foo', [1] > 42);

Expected result:
----------------
E_STRICT
NULL
E_STRICT
NULL


Actual result:
--------------
bool(true)
bool(true)

Hi,
I've faced this issue recently. An array was mistakenly compared to an integer and no notice was emitted.
I'm not in favor to change the result of a such comparison but raising a notice would be a great help.
