Through a coding error of mine, I stumbled upon a "feature" of variable
variables, that is quite sickening to me. Usually php doesn't support an empty string or integers as variable-names, but these things are all possible and you won't get a single warning...shouldn't this get changed?
<?php
$varname = "";
//$varname = 6;
$$varname = new stdClass();
${""}->{""} = "bar";
//${"6"}->{"6"} = "bar";
$$varname->$varname = "foo";
?>
Regards,
Alexander
