PHP Object Array from API call

Question

I have made an API call $client->orders->get() and I get a response with the data formatted like:

Array ( [0] => stdClass Object ( [id] => 5180 [order_number] => 5180 [created_at] => 2016-12-21T14:50:08Z [updated_at] => 2016-12-21T15:01:51Z [completed_at] => 2016-12-21T15:01:52Z [status] => completed [currency] => GBP [total] => 29.00 [subtotal] => 29.00 [total_line_items_quantity] => 1 [total_tax] => 0.00 [total_shipping] => 0.00 [cart_tax] => 0.00 [shipping_tax] => 0.00 [total_discount]...........

So I loop through the data:

foreach ( $client->orders->get() as $order ) {

// skip guest orders (e.g. orders with customer ID = 0)
print_r($order);
    echo $order[0];
    echo $order->subtotal;
}

Trouble I have is outputting the data, if I use the print_r function I get an output but I don't know how to access the individual elements of the array.

If I try:

echo $order[0].[id];

I get:

Catchable fatal error: Object of class stdClass could not be converted to string in.

I have searched high and low on this but I just can't find anything I understand. Help please... :)

Answer 1

The $order within the following loop

foreach ( $client->orders->get() as $order ) { .. }

is each of elements that belongs to this $client->orders->get() array and they are in the form of object.

thus to output ( for e.g the subtotal entry) you do echo $order->subtotal :

foreach ( $client->orders->get() as $order ) { $order->subtotal }

• echo $order[0] (inside the loop) is invalid, because doing so is treating the $order as an array meanwhile its type is object. Do $order->somefields instead to reference its properties.
• print_r($order) (inside the loop) is valid because you can use print_r to print the properties of object.
• $client->orders->get()[0]->subtotal (if put outside the loop) is also valid.

Just in case the array's elements contains both form of object or array

$myarray = $client->orders->get();

• // True because the first element is object echo (is_object($myarray[0])) ? 'True':'False';

• // False because the first element is object, not an array echo is_array($myarray[0]) ? 'True':'False';

And for this

// the same with echo is_array($client->orders->get()) ? 'True':'False';
echo is_array($myarray) ? 'True':'False';

sure that would be true, .

You can access the subtotal column value without using foreach loop. Here is the code.

$response = $client->orders->get();
$subtotal = $response[0]->subtotal;

If you would like to use foreach then you can access like this.

foreach ( $client->orders->get() as $order ) {
 echo $order->order_number;
}
