Question

Ok, I’m very new to PHP. I will try my best to explain my question.

This is a var_dump of a json object.
What i am trying to do is access the information in the ‘register_sale_products’ object.
It contains product info like SKU, Price etc of the products in each sale. In the example below i am trying to list the SKU’s.

object(stdClass)[1]
  public 'register_sales' => 
    array
      0 => 
        object(stdClass)[2]
          public 'id' => string '7c969b77-6825-bc65-3e04-64f922a570eb' (length=36)
          public 'register_id' => string '07709f8e-8d90-11e0-8e09-4040f540b50a' (length=36)
          public 'invoice_number' => string 'BH8464' (length=6)
          public 'register_sale_products' => 
            array
              ...
          public 'totals' => 
            object(stdClass)[6]
              ...
          public 'register_sale_payments' => 
            array
              ...
      1 => 
        object(stdClass)[9].......

I managed to get one SKU from the first “Product” object array ‘register_sale_products’ using this code.

$array = array()    ;
foreach($data->register_sales as $sale){
    $array =    $sale->register_sale_products ;
    }
foreach($array as $saleprod){
        $details = explode(' / ', $saleprod->sku);
    $result = $details[0];
    }
echo $result;

I really need to get an a result of each object in the array.
Any help much appreciated.

You are overwriting $result every time this loops:

foreach($array as $saleprod){
    $details = explode(' / ', $saleprod->sku);
    $result = $details[0];
}
echo $result;

What you have to do is echo inside the loop, let $result be a new array or let $result be a string which you append to:

foreach($array as $saleprod){
    $details = explode(' / ', $saleprod->sku);
    echo $details[0], '<br>';
}

// or
$result = array();
foreach($array as $saleprod){
    $details = explode(' / ', $saleprod->sku);
    $result[] = $details[0];
}
foreach($result as $r) {
    echo $r;
}

//or
$result = '';
foreach($array as $saleprod){
    $details = explode(' / ', $saleprod->sku);
    $result .= $details[0] . ' ';
}
echo $result;
