Persian google search api in PHP

Question

I am using Google web search API in my PHP(laravel) app for search a Persian(farsi) word in web ...

I am using this code for this :

<?php

$url = "https://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=فارسی&userip=192.168.106.1";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_REFERER, 'http://cafesearch.ir/');
$body = curl_exec($ch);
curl_close($ch);

$json = json_decode($body);
var_dump($json->responseData);

there are not any problems with English , but in Persian I have not any results...

How I can solve this problem?

Answer 1

You need to encode the Persian bit of your url using php's urlencode method.

So basically change your url's definition as the following.

$keyword = urlencode('فارسی');    
$url     = "https://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=$keyword&userip=192.168.106.1";

using this will give me the following output, which is matching with the result you may get when visiting the original url in your browser

class stdClass#2 (2) {
  public $results =>
  array(4) {
    [0] =>
    class stdClass#3 (8) {
      public $GsearchResultClass =>

      public $unescapedUrl =>
