I POST a form with
<select name="2size">

and I read it back with  
if (isset ($HTTP_POST_VARS['2size']))
{$size = $HTTP_POST_VARS['2size'];
}

PHP 4.2 accepts this without errors. Isn't this considered an illegal variable name? PHP Manual says: "A valid variable name starts with a letter or underscore,"

The manual is right, but there is no variable named '2size', it just a key in a hash which is perfectly valid.
