Question

so I acquired a json object from an API and json decoded it…

but then the returned object is of the following:

stdClass Object
(
    [id] => stdClass Object
        (
            [$t] => some string
        )
)

And as you can see there is a property with a $ sign in it

but when I do $object->id->$t <–that returns error since it thinks $t is a variable

how would I go about fetching that variable with $ sign?

Answer 1

Encapsulate it as a single-quoted string:

echo $object->id->{'$t'};

Note that you cannot use double quotes for the same reason you cannot use $object->id->$t: PHP will attempt to interpolate $t. However, you could use double quotes if you escape the dollar sign:

echo $obj->id->{"\$t"};

You can see it working in this simple demo.
