php获取当前网址与页面内容的代码参考

3. /**

4. * 得到当前网址
5. * eidt by bbs.it-home.org
6. */
7. function get_url() {
8. $sys_protocal = isset($_SERVER['SERVER_PORT']) && $_SERVER['SERVER_PORT'] == '443' ? 'https://' : 'http://';
9. $php_self = $_SERVER['PHP_SELF'] ? $_SERVER['PHP_SELF'] : $_SERVER['SCRIPT_NAME'];
10. $path_info = isset($_SERVER['PATH_INFO']) ? $_SERVER['PATH_INFO'] : '';
11. $relate_url = isset($_SERVER['REQUEST_URI']) ? $_SERVER['REQUEST_URI'] : $php_self.(isset($_SERVER['QUERY_STRING']) ? '?'.$_SERVER['QUERY_STRING'] : $path_info);
12. return $sys_protocal.(isset($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : '').$relate_url;
13. }

14. //输出当前网址

15. $url = get_url();
16. echo $url;
17. ?>

2，获取页面内容的代码

3. /**

4. * 得到页面内容
5. * edit by bbs.it-home.org
6. */
7. function get_contents($url){
8. if(function_exists('file_get_contents')){
9. $file_contents = file_get_contents($url);
10. }else{
11. $ch = curl_init();
12. $timeout = 5;
13. curl_setopt ($ch, CURLOPT_URL, $url);
14. curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
15. curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
16. $file_contents = curl_exec($ch);
17. curl_close($ch);
18. }

19. //输出内容

20. return $file_contents;
21. ?>
