Question

How can I loop through this array and print one result in each line. This is returned by google search api.

This works for me

print_r($rez->responseData);

But this doesn’t

print_r($rez->responseData->results); nor this print_r($rez->responseData['results']);

Below is the array

        stdClass Object
(
    [results] => Array

Answer 1

Something like:

$obj = new obj(); // your object

function printLies($obj)
{
    foreach ($obj as $elem)
    {
        if (is_array($elem) || is_object($elem))
        {
            printLies($obj);
        }
        else
        {
            echo $elem . '<br />';
        }
    }
}

Or I didn’t understand the question? Maybe you meant this?

$obj = new obj(); // your object

foreach ($obj->result as $result)
{
    print_r($result);
}
