<?php session_start();      $client_id = '';     $client_secret = '';     $api_key = '';     $redirect_uri = 'http://localhost:8888/oauth';     $scope = "https://www.googleapis.com/auth/plus.me";      if (!isset($_request['code']))     {         $login_path = "https://accounts.google.com/o/oauth2/auth?";         $login_path .= "redirect_uri=" . $redirect_uri;         $login_path .= "&response_type=code";         $login_path .= "&client_id=" . $client_id;         $login_path .= "&approval_prompt=force";         $login_path .= "&scope=" . $scope;         $login_path .= "&access_type=offline";          echo "<a href='" . $login_path . "'>login</a>";     }      else     {          $ch = curl_init();          curl_setopt($ch, curlopt_url, "https://accounts.google.com/o/oauth2/auth");          curl_setopt($ch, curlopt_post, true);          // option set true response         // doesnot printed , stored directly in         // variable         curl_setopt($ch, curlopt_returntransfer, true);          $post_params = "code=" . $_request['code'] . "&";         $post_params = "redirect_uri=" . $redirect_uri . "&";         $post_params .= "client_id=" . $client_id . "&";         $post_params .= "scope=" . $scope . "&";         $post_params .= "client_secret=" . $client_secret . "&";         $post_params .= "grant_type=authorization_code&";         $post_params .= "response_type=code";           curl_setopt($ch, curlopt_postfields, $post_params);          $data = curl_exec($ch);          curl_close($ch);          //commented since data showing empty         //$data = json_decode($data);          print '<pre>';         print $data;         print '</pre>'; } 

update: else having same problem figured out. here working code.

$client_id = ''; $client_secret = ''; $api_key = ''; $redirect_uri = 'http://localhost:8888/oauth'; $scope = "https://www.googleapis.com/auth/plus.me"; $api_call = "https://www.googleapis.com/plus/v1/people/me?access_token=";  if (!isset($_request['code'])) {     $login_path = "https://accounts.google.com/o/oauth2/auth?";     $login_path .= "redirect_uri=" . $redirect_uri;     $login_path .= "&response_type=code";     $login_path .= "&client_id=" . $client_id;     $login_path .= "&approval_prompt=force";     $login_path .= "&scope=" . $scope;     $login_path .= "&access_type=offline";      echo "<a href='" . $login_path . "'>login</a>"; }  else {      $ch = curl_init();      curl_setopt($ch, curlopt_url, "https://accounts.google.com/o/oauth2/token");      curl_setopt($ch, curlopt_post, true);      // option set true response     // doesnot printed , stored directly in     // variable     curl_setopt($ch, curlopt_returntransfer, true);       $post_params = "code=" . $_request['code'] . "&";     $post_params .= "redirect_uri=" . $redirect_uri . "&";     $post_params .= "client_id=" . $client_id . "&";     $post_params .= "scope=" . $scope . "&";     $post_params .= "client_secret=" . $client_secret . "&";     $post_params .= "grant_type=authorization_code&";      curl_setopt($ch, curlopt_postfields, $post_params);      $data = curl_exec($ch);      curl_close($ch);      $data = json_decode($data);      $access_token = $data->access_token;     $refresh_token = $data->refresh_token;      // end of oauth call google plus api. not $api_call holds request uri value     $call = $api_call . $access_token;     $ch = curl_init();     curl_setopt($ch, curlopt_url, $call);     curl_setopt($ch, curlopt_returntransfer, true);     $out = curl_exec($ch);      echo '<pre>';     print_r($out);     echo '</pre>';
