Thank you for the report, and for helping us make our documentation

"Accessing by [] or {} to variables of other type silently returns
NULL."

Surely it is intended.

OK, so we're back at Feature/Change Request. Except on further thought
I like the way it works and would prefer it not change. I just want
clarification of what is supposed to happen when you apply square
brackets to a non-array.
If it is working as intended (silenty returns NULL), please document
it.
If it isn't working as intended, please fix it.

Change requests belong to the "Feature/Change Request" category.
Reclassified.

Changed category... I thought I put it in as "Arrays related", but I
guess I missed and it ended up as "Feature/Change Request". To me, this
is either a bug, or a documentation improvement request, not a feature
request.

Description:
------------
If I index a scalar or NULL variable as if it were an array, I get NULL
back with no warning or notice. This is true for any index value,
including 0. I expected an Undefined offset or incorrect type message.
The manual says an integer variable = n will convert to array(0=>$n);
that works on casting to array but not on indexing.
Reproduce code:
---------------
<?php
error_reporting(E_ALL+E_STRICT);
$arry = array(1=>1);
$notarry = NULL;
$intvar = 123;
echo "1. arry[1] = " . $arry[1] . "\n";
echo "2. arry[2] = " . $arry[2] . "\n";
echo "3. intvar[0] = " . $intvar[0] . "\n";
echo "4. intvar[1] = " . $intvar[1] . "\n";
echo "5. notarry[1] = " . $notarry[1] . "\n";
Expected result:
----------------
"Notice: Undefined offset" (or incorrect type) for (2), (3), (4), and
(5). Or maybe (3) should echo "123" via implicit cast. But only (2)
raises a Notice; the others just echo NULL.
Actual result:
--------------
1. arry[1] = 1
Notice: Undefined offset: 2 in /a5/home/ljb/lang/php/p.php on line 7
2. arry[2] =
3. intvar[0] =
4. intvar[1] =
5. notarry[1] =
