PHP Dynamic Variable Name

Question

I want a dynamic property name like this:

$_taxVocabName = 'name';
$node->field_ . $_taxVocabName;

This should call:

$node->field_name

How can I do this?

I could not find anything on php.net or elsewhere.

Thanks Sascha

php.net/manual/en/language.variables.variable.php this is what you want I think — Oli

Two ways:

First, use a variable:

$property = 'field_' . $_taxVocabName;

$node->$property;

Second, use curly brackets:

$node->{'field_' . $_taxVocabName};

I'd think a much better way to do this would be

$taxVocabName = "name";
$property = "field_" . $taxVocabName;

Then you would have to set the variable to a value of course...

like so:

$$property = "My variable variable";

or:

$field_name = "My variable variable";

I know it's a bit later, but maybe this will help someone else down the road.
