Return PHP object by index number (not name)

Question

Goal: retrieve an element of data from within a PHP object by number.

This is the print_r($data) of the object:

stdClass Object
(
    [0] => stdCl         


        

Answer 1

Normally, PHP variable names can't start with a digit. You can't access $data as an array either as stdClass does not implement ArrayAccess — it's just a normal base class.

However, in cases like this you can try accessing the object attribute by its numeric name like so:

echo $data->{'0'}->UserName;

The only reason I can think of why Spudley's answer would cause an error is because you're running PHP 4, which doesn't support using foreach to iterate objects.
