Extending a class with a variable?

[law]

This works and is tested.

PHP Code:

$data_stats = json_decode($ret);
$projected_points = $data_stats->body->player_stats->42550689->FPTS 

I just need to know how to do it using a variable. Something like this:

PHP Code:

$data_stats = json_decode($ret);
$projected_points = $data_stats->body->player_stats->$id->FPTS 

How can I make $id work here?

 

Also is this called extending a class? I don't even know the correct terminology to describe my question.

No, extending a class is a completely different thing.

 

Can you give us the print_r of $data_stats?

[DavidAM]

Hm, I'm surprised it works. I did not think that methods or properties could start with a digit.

 

However,  to use a variable in that expression, you would put it in curly braces:

$projected_points = $data_stats->body->player_stats->{$id}->FPTS 

I've used it with property names and method calls, but never in the middle of a chain like that, so YMMV.

 

Oh, and NO, this is not what is meant by "extending a class" (unless I am really out of the loop here).

KevinM1 here is a snippet of the print r (it contains 100,000+ entries):

 

stdClass Object
(
    [body] => stdClass Object
        (
            [player_stats] => stdClass Object
                (
                    [1749143] => stdClass Object
                        (
                            [_empty_] => 0
                            [TM] => SEA
                            [FPTS] => 0
                            [GS] => 16.0
                            [G] => 16.0
                            [Pos] => LB
                        )

                    [1616752] => stdClass Object
                        (
                            [_empty_] => 0
                            [CmpPct] => 0
                            [FPTS] => 0
                            [RuAvg] => 0
                            [YAtt] => 0
                            [GS] => 16.0
                            [Pos] => RB
                            [TM] => PIT
                            [ReAvg] => 0
                            [G] => 16.0
                        )

 

My goal is to access these ids to pull the FPTS out.

 

DavidAM: I am getting a T_VARIABLE issue.

 

How should I describe this question? Sorry for the ignorance.

[DavidAM]

I would just json_decode it as an array instead of as objects. Then you can reference them as array keys:

 

$data_stats = json_decode($ret, true);
$projected_points = $data_stats['body']['player_stats'][$id]['FPTS'];

Thank you DavidAM, I found the error was due to my stupidity at checking the cleanliness of my code.

 

Both your array suggestion

and

$projected_points = $data_stats->body->player_stats->{$id}->FPTS;

work and are very helpful.

 

Thank you guys for the help.
