I want to print value of sku , name, price using foreach loop

Since im new to it i first started printing a single value

echo $data->items->arr[0]->sku;
Notice: Trying to get property of non-object  getting this error

but i want to print the values in foreach please help!

Answer 1

Items is a property of the main object, and in itself is an array. This is what you're after:

foreach($data->items as $d) {
   echo $d->name, '<br />', $d->sku, '<br />', $d->price;
}

If you want to access one of those element without a loop, you need to provide the array index, for example:

echo $data->items[0]->name

Answer 2

the easy way for you is convert object to array

function array2object($array) {

    if (is_array($array)) {
        $obj = new StdClass();

        foreach ($array as $key => $val){
            $obj->$key = $val;
        }
    }
    else { $obj = $array; }

    return $obj;
}

function object2array($object) {
    if (is_object($object)) {
        foreach ($object as $key => $value) {
            $array[$key] = $value;
        }
    }
    else {
        $array = $object;
    }
    return $array;
}


// example:

$array = array('foo' => 'bar', 'one' => 'two', 'three' => 'four');

$obj = array2object($array);

print $obj->one; // output's "two"

$arr = object2array($obj);

print $arr['foo']; // output's bar

Answer 3

foreach($data['items'] as $item) {

   echo $item['sku'].PHP_EOL
   echo $item['name'].PHP_EOL
   echo $item['price'].PHP_EOL;

}
