Search google+ api for public posts and pages - php

Question

I'm trying to use the google-api-php-client SDK along with google plus api service. The documentation isnt very clear. Do I search activities? Do I need to get an oAuth token to do what i want?
Update: Now using
$params = array(
'orderBy' => 'best',
'maxResults' => '20',
'query' => 'Google+ API'
);
$results = $plus->activities->search($params);
returns
Array
(
[kind] => plus#activityFeed
[etag] => "5NTCbsXue5u92XtxuV0QeM_x9B4/58mHUy-IErItGIABIAhYhhUjJ-M"
[selfLink] => https://www.googleapis.com/plus/v1/activities?query&maxResults=10
[title] => Plus Search

Answer 1

I had a same problem and here is how I have done it:
$query = "some query";
$params = array(
'orderBy' => 'best',
'maxResults' => '20',
);
$results = $plus->activities->search($query, $params);
foreach($results['items'] as $result) {
print "Result: {$result['object']['content']}\n";
}
Even dough in an examples query is a part of parameters it is not. It should be sent as separated value as you can see in the implementation of the search method for plus service Link
Hope this helps you.

You don't need an OAuth token to search activities. You only need to register a Developer Key in the Google APIs Console.
Register a Developer Key in the Google APIs Console.
Check out the latest version of the Google APIs PHP Client .
Take a look at the Google+ sample app. https://code.google.com/p/google-api-php-client/source/browse/trunk/examples/plus/index.php
Sample:
$params = array(
'orderBy' => 'best',
'maxResults' => '20',
'query' => 'Google+ API'
);
$results = $plus->activities->search($params);
foreach($results['items'] as $result) {
print "Result: {$result['object']['content']}\n";
}
