这篇文章主要介绍了php实现的Curl封装类Curl.class.php用法,以完整实例形式较为详细的分析了Curl封装类的定义及相关使用技巧,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实现的Curl封装类Curl.class.php用法，分享给大家供大家参考，具体如下：

1. <?php
2. //curl类
3. class Curl
4. {
5. function Curl(){
6. return true;
7. }
8. function execute($method, $url, $fields='', $userAgent='', $httpHeaders='', $username='', $password=''){
9. $ch = Curl::create();
10. if(false === $ch){
11. return false;
12. }
13. if(is_string($url) && strlen($url)){
14. $ret = curl_setopt($ch, CURLOPT_URL, $url);
15. }else{
16. return false;
17. }
18. //是否显示头部信息
19. curl_setopt($ch, CURLOPT_HEADER, false);
20. //
21. curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
22. if($username != ''){
23. curl_setopt($ch, CURLOPT_USERPWD, $username . ':' . $password);
24. }
25. $method = strtolower($method);
26. if('post' == $method){
27. curl_setopt($ch, CURLOPT_POST, true);
28. if(is_array($fields)){
29. $sets = array();
30. foreach ($fields AS $key => $val){
31. $sets[] = $key . '=' . urlencode($val);
32. }
33. $fields = implode('&',$sets);
34. }
35. curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
36. }else if('put' == $method){
37. curl_setopt($ch, CURLOPT_PUT, true);
38. }
39. //curl_setopt($ch, CURLOPT_PROGRESS, true);
40. //curl_setopt($ch, CURLOPT_VERBOSE, true);
41. //curl_setopt($ch, CURLOPT_MUTE, false);
42. curl_setopt($ch, CURLOPT_TIMEOUT, 10);//设置curl超时秒数
43. if(strlen($userAgent)){
44. curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);
45. }
46. if(is_array($httpHeaders)){
47. curl_setopt($ch, CURLOPT_HTTPHEADER, $httpHeaders);
48. }
49. $ret = curl_exec($ch);
50. if(curl_errno($ch)){
51. curl_close($ch);
52. return array(curl_error($ch), curl_errno($ch));
53. }else{
54. curl_close($ch);
55. if(!is_string($ret) || !strlen($ret)){
56. return false;
57. }
58. return $ret;
59. }
60. }
61. function post($url, $fields, $userAgent = '', $httpHeaders = '', $username = '', $password = ''){
62. $ret = Curl::execute('POST', $url, $fields, $userAgent, $httpHeaders, $username, $password);
63. if(false === $ret){
64. return false;
65. }
66. if(is_array($ret)){
67. return false;
68. }
69. return $ret;
70. }
71. function get($url, $userAgent = '', $httpHeaders = '', $username = '', $password = ''){
72. $ret = Curl::execute('GET', $url, '', $userAgent, $httpHeaders, $username, $password);
73. if(false === $ret){
74. return false;
75. }
76. if(is_array($ret)){
77. return false;
78. }
79. return $ret;
80. }
81. function create(){
82. $ch = null;
83. if(!function_exists('curl_init')){
84. return false;
85. }
86. $ch = curl_init();
87. if(!is_resource($ch)){
88. return false;
89. }
90. return $ch;
91. }
92. }
93. ?>

GET用法：

$curl = new Curl();

$curl->get('http://www.phpfensi.com/');

POST用法：

$curl = new Curl();

$curl->get('http://www.phpfensi.com/', 'p=1&time=0');

希望本文所述对大家的php程序设计有所帮助。
