string to attribute name in PHP classs

Hi

This works fine:

echo $xml -> value;

PHP:

but this doesn't:

$v = "value";
echo $xml -> $v;

PHP:

I'd get this error:
Notice: Array to string conversion in...

How can I change that string so php interprets it to an attribute name?

 

echo $xml->{$value};

try that

 

Are you suer you're using the exact same code you posted, or are you using a pseudo example ?
That should work as-is.
