Php-based backup database ZIP and export-PHP Tutorial

Use php to ZIP and export the backup database. In some open-source PHP systems, we often see Methods for backing up and exporting databases. In fact, the code is not complicated. The following describes the two methods, taking WINDOWS as an example, one is that directories are often found in some PHP open-source systems and there are methods for backing up databases and exporting them. in fact, the code is not complex. below
Take WINDOWS as an example. There are two methods: One is that the directory folder must have the permission to execute scripts,
The code is as follows:

1)

Java code
1. 2.
3. $ username = "root ";
4. $ password = "";
5. $ hostname = "localhost ";
6. $ dbname = "test ";
7.
8.
9. $ dumpfname = $ dbname. "_". date ("Y-m-d_H-i-s"). ". SQL ";
10. $ command = "C: \ xampp \ mysql \ bin \ mysqldump -- add-drop-table -- host = $ hostname
11. -- user = $ username ";
12. if ($ password)
13. $ command. = "-- password =". $ password ."";
14. $ command. = $ dbname;
15. $ command. = ">". $ dumpfname;
16. system ($ command );
17.
18. // zip data file
19. $ zipfname = $ dbname. "_". date ("Y-m-d_H-i-s"). ". zip ";
20. $ zip = new ZipArchive ();
21. if ($ zip-> open ($ zipfname, ZIPARCHIVE: CREATE ))
22 .{
23. $ zip-> addFile ($ dumpfname, $ dumpfname );
24. $ zip-> close ();
25 .}
26.
27. // read zip file and send it to standard output
28. if (file_exists ($ zipfname )){
29. header ('content-Description: File Transfer ');
30. header ('content-Type: application/octet-stream ');
31. header ('content-Disposition: attachment; filename = '. basename ($ zipfname ));
32. flush ();
33. readfile ($ zipfname );
34. exit;
35 .}
36.?>

Method 2: The folder has no related permissions.
Java code
1. 2. ob_start ();
3.
4. $ username = "root ";
5. $ password = "";
6. $ hostname = "localhost ";
7. $ dbname = "test ";
8.
9. $ command = "C: \ xampp \ mysql \ bin \ mysqldump -- add-drop-table -- host = $ hostname
10. -- user = $ username ";
11. if ($ password)
12. $ command. = "-- password =". $ password ."";
13. $ command. = $ dbname;
14. system ($ command );
15.
16. $ dump = ob_get_contents ();
17. ob_end_clean ();
18.
19.
20. // no ZIP
21. header ('content-Description: File Transfer ');
22. header ('content-Type: application/octet-stream ');
23. header ('content-Disposition: attachment; filename = '. basename ($ dbname ."_".
24. date ("Y-m-d_H-i-s"). ". SQL "));
25. flush ();
26. echo $ dump;
27. exit ();]>
