Description:
------------
<pre>
file NumericVarName.php
<?php
$TestVar = 8888;
$$TestVar = 'See the KEY\'s type...';
$SeeThis = get_defined_vars();
function MyEcho($_Msg) {echo '<script>alert(\'' . $_Msg .
'\');</script>';}
isset($$TestVar) && MyEcho('Case A!');
isset($SeeThis[8888]) && MyEcho('Case B!');
isset($SeeThis['8888']) && MyEcho('Case C!');
foreach ($SeeThis as $_Ui => $_Uk) {
($_Ui === 8888) && $_Temp = 'Case B too!';
($_Ui === '8888') && $_Temp = 'Case C too!';
isset($_Temp) && MyEcho($_Temp);
}
?>

My English is poor.Just explain my question shortly:
The output contains "Case A!" & "Case C too!",
but why not contain "Case C!" before "Case C too!" ?
------------------------------------------------------------------------------
Hope you can analyse what I've talk about,
maybe something not expect comes such as:
- syntax-parser do not check "$$var" when "$var" is numeric.
- do "foreach array" with get_defined_vars()'s return has a
shortcoming.
- ...
Wish PHP better & better...
