Re: Variable variables into an array.

Hi. Quick set of eyes needed to see what I've done wrong... The following is a reduced example ... <?php $Set = array(); $Entry = 'Set[1]'; $Value = 'Assigned'; $$Entry = $Value; print_r($Set); ?> The output is an empty array. Examining $GLOBALS, I end up with an entries ...

    [Set] => Array
        (
        )

    [Entry] => Set[1]
    [Value] => Assigned
    [Set[1]] => Assigned

According to http://docs.php.net/manual/en/language.variables.basics.php, a variable named Set[1] is not a valid variable name. The [ and ] are not part of the set of valid characters. In testing all the working V4 and V5 releases I have, the output is always an empty array, so it looks like it is me, but the invalid variable name is an issue I think. Regards, Richard. NOTE: The above is a simple test. I'm trying to map in nested data to over 10 levels.

For something like this, a string that looks like a nested array reference, you might need to involve eval for it to "derive" that nested array.
