Method 1:

2. // Description: obtain a url without parameters.
3. Function curpageurl ()
4. {
5. $ Pageurl = 'http ';
6. If ($ _ server ["https tutorial"] = "on ")
7. {
8. $ Pageurl. = "s ";
9. }
10. $ Pageurl. = "://";
11. If ($ _ server ["server_port"]! = "80 ")
12. {
13. $ Pageurl. = $ _ server ["server_name"]. ":". $ _ server ["server_port"]. $ _ server ['php _ self '];
14. }
15. Else
16. {
17. $ Pageurl. = $ _ server ["server_name"]. $ _ server ['php _ self '];
18. }
19. Return $ pageurl;
20. }
21. ?>

Method 2

2. // Description: obtain the complete url
3. Function curpageurl ()
4. {
5. $ Pageurl = 'http ';
6. If ($ _ server ["https"] = "on ")
7. {
8. $ Pageurl. = "s ";
9. }
10. $ Pageurl. = "://";
11. If ($ _ server ["server_port"]! = "80 ")
12. {
13. $ Pageurl. = $ _ server ["server_name"]. ":". $ _ server ["server_port"]. $ _ server ["request_uri"];
14. }
15. Else
16. {
17. $ Pageurl. = $ _ server ["server_name"]. $ _ server ["request_uri"];
18. }
19. Return $ pageurl;
20. }
21. ?>

In addition, $ _ server ['request _ url'] and $ _ server ['request _ url'] are slightly different:

$ _ Server ["request_uri"] returns the complete path (/directory/file. ext? Query = string)

$ _ Server ['request _ url'] returns only the file path, excluding parameters (/directory/file. ext), similar to $ _ server ['php _ self '], except that $ _ server ['request _ url'] is unavailable on some servers.
