PHP read first item in object array - php

Question

I have my code in PHP which is returning this Array of data:
GoCardlessPro\Core\ListResponse Object
(
[records] => Array
(
[0] => GoCardlessPro\Resources\Mandate Object
(
[model_name:protected] => Mandate
[created_at:protected] => 2017-04-01T16:49:09.642Z
[id:protected] => ID001
[links:protected] => stdClass Object
(
[customer_bank_account] => CB001
[creditor] => CR001
[customer] => CU001
)
[metadata:protected] => stdClass Object
(
)
[next_possible_charge_date:protected] => 2017-04-06
[payments_require_approval:protected] =>
[reference:protected] => RE001
[scheme:protected] => bacs
[status:protected] => active
[data:GoCardlessPro\Resources\BaseResource:private] => stdClass Object
(
[id] => 123
[created_at] => 2017-04-01T16:49:09.642Z
[reference] => RE001
[status] => active
[scheme] => bacs
[next_possible_charge_date] => 2017-04-06
[payments_require_approval] =>
[metadata] => stdClass Object
(
)
[links] => stdClass Object
(
[customer_bank_account] => 001
[creditor] => CR001
[customer] => CU001
)
)
[api_response] =>
)
)
)
I want to be able to read the ID of the first item in therecords array.
This data is contained inside a variable called $GC_Mandate;
I have tried these:
echo $GC_Mandate->records->{0}->id;
echo $GC_Mandate->records->0->id;
echo $GC_Mandate->records->[0]->id;
$GC_Mandate = $GC_Mandate->records;
echo $GC_Mandate->{0}->id;
But none will return the data

Answer 1

To get the first record, the syntax you need is $GC_Mandate->records[ 0 ].
However, that object is a GoCardlessPro\Resources\Mandate object and its member id is protected1, so we'd need to know the interface of GoCardlessPro\Resources\Mandate (its public methods1), to know if we can somehow retrieve the value of id.
My guess would be getId(), so the full syntax would become
$GC_Mandate->records[ 0 ]->getId()
But, that's just a guess. You'd have to look into the documentation/class definition of GoCardlessPro\Resources\Mandate, to be sure if you can retrieve id.
Turns out (provided I'm linking to the correct github repository) you can do:
$GC_Mandate->records[ 0 ]->id
since GoCardlessPro\Resources\Mandate extends GoCardlessPro\Resources\BaseResource, which exposes the protected members through GoCardlessPro\Resources\BaseResource::__get()2.
1. visibility in PHP
2. magic methods in PHP

Answer 2

I can't comment so I guess I'll have to post.
You should try to print_r($GC_Mandate); and see what it gives out and then go from there.

Answer 3

Try $GC_Mandate->records[0]->__get('id')

Answer 4

it will return all data ..for perticulat data put this in foreach loop
print_r($GC_Mandate['records']);
