How to loop through this array and print one result in each line using php

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

This is the code that generates this.

<?php 

/**
 * google_search_api()
 * Query Google AJAX Search API
 *
 * @param array $args URL arguments. For most endpoints only "q" (query) is required.
 * @param string $referer Referer to use in the HTTP header (must be valid).
 * @param string $endpoint API endpoint. Defaults to 'web' (web search).
 * @return object or NULL on failure
 */
function google_search_api($args, $referer = 'http://localhost/test/', $endpoint = 'web'){
    $url = "http://ajax.googleapis.com/ajax/services/search/".$endpoint;

    if ( !array_key_exists('v', $args) )
        $args['v'] = '1.0';

    $url .= '?'.http_build_query($args, '', '&');

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    // note that the referer *must* be set
    curl_setopt($ch, CURLOPT_REFERER, $referer);
    $body = curl_exec($ch);
    curl_close($ch);
    //decode and return the response
    return json_decode($body);
}


print_r($rez->responseData);

Is it not possible to improve the format of this question. It is unreadable that way. — Ivaylo Strandjev

Please print_r your array and copy the result from the view source, and not the actual page. Place that here. — Madara's Ghost

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);
}

Can you give me an example what exactly result do you need with current array?

I didn't need a code. I'm trying to understand what do you want to get as a result.
