这篇文章主要介绍了PHP封装的Twitter访问类,通过curl调用实现针对Twitter的常用访问功能,具有一定参考借鉴价值,需要的朋友可以参考下，本文实例讲述了PHP封装的Twitter访问类，分享给大家供大家参考，具体如下：

1. class Twitter {
2. /**
3. * Method to make twitter api call for the users timeline in XML
4. *
5. * @access private
6. * @param $twitter_id, $num_of_tweets
7. * @return $xml
8. */
9. private function api_call($twitter_id, $num_of_tweets) {
10. $c = curl_init();
11. curl_setopt($c, CURLOPT_URL, "http://twitter.com/statuses/user_timeline/$twitter_id.xml?count=$num_of_tweets");
12. curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
13. curl_setopt($c, CURLOPT_CONNECTTIMEOUT, 3);
14. curl_setopt($c, CURLOPT_TIMEOUT, 5);
15. $response = curl_exec($c);
16. $response_info = curl_getinfo($c);
17. curl_close($c);
18. if (intval($response_info['http_code']) == 200) {
19. $xml = new SimpleXMLElement($response);
20. return $xml;
21. } else {
22. return false;
23. }
24. }
25. /**
26. * Method to add hyperlink html tags to any urls, twitter ids or hashtags in tweet
27. *
28. * @access private
29. * @param $text
30. * @return $text
31. */
32. private function process_links($text) {
33. $text = utf8_decode($text);
34. $text = preg_replace('@(https?://([-\w\.]+)+(d+)?(/([\w/_\.]*(\?\S+)?)?)?)@', '<a href="$1">$1</a>', $text);
35. $text = preg_replace("#(^|[\n ])@([^ \"\t\n\r<]*)#ise", "'\\1<a href=\"http://www.twitter.com/\\2\" >@\\2</a>'", $text);
36. $text = preg_replace("#(^|[\n ])\#([^ \"\t\n\r<]*)#ise", "'\\1<a href=\"http://hashtags.org/search?query=\\2\" >#\\2</a>'", $text);
37. return $text;
38. }
39. /**
40. * Main method to retrieve the tweets and return html for display
41. *
42. * @access public
43. * @param $twitter_id, $num_of_tweets, $timezone
44. * @return $result
45. */
46. public function get_tweets($twitter_id, $num_of_tweets = 3, $timezone = "America/Denver") {
47. $include_replies = false;
48. date_default_timezone_set($timezone);
49. // the html markup
50. $cont_o = "<div tweets\">\n";
51. $tweet_o = "<div class=\"status\">\n";
52. $tweet_c = "</div>\n\n";
53. $detail_o = "<div class=\"details\">\n";
54. $detail_c = "</div>\n\n";
55. $cont_c = "</div>\n";
56. if ($twitter_xml = $this->api_call($twitter_id, $num_of_tweets)) {
57. $result = $cont_o;
58. foreach ($twitter_xml->status as $key => $status) {
59. if ($include_replies == true | substr_count($status->text, "@") == 0 | strpos($status->text, "@") != 0) {
60. $tweet = $this->process_links($status->text);
61. $result .= $tweet_o . $tweet . $tweet_c . $detail_o . date('D jS M y H:i', strtotime($status->created_at)) . $detail_c;
62. }
63. }
64. $result .= $cont_c;
65. } else {
66. $result .= $cont_o . $tweet_o . "Twitter seems to be unavailable at the moment." . $tweet_c . $cont_c;
67. }
68. return $result;
69. }
70. }
