NOW INSTALL THE NEW XAMPP!

1. Download the latest version of XAMPP.
2. Install it in the same drive where your old xampp currently installed.
3. Now run the xampp control panel as Administrator.
4. Start both Apachee and MySQL server and check whether they are working properly or not, also check PhpMyAdmin page.
5. Now Copy the htdocs folder from ‘xampp-old’ folder to ‘xampp’ folder.
6. Go to xampp\php\php.ini
7. You can use CLI for importing database. It specially helps with very big databases. If so you can jump to step 19. If not follow the remaining steps.
8. Now configure the php.ini file and increase the value for the following options upload_max_filesize,memory_limit, post_max_size .
9. post_max_size and memory_limit need to be larger than upload_max_filesize. Make them high enough so big files can work on the server.
10. Go to ‘xampp\phpMyAdmin\libraries\config.default.php’
11. Look for $cfg[‘ExecTimeLimit’] = 800;
12. Change the value 800 to a higher value may be 8000.
13. Now restart both Apache and MySQL server.
14. Now go to phpMyAdmin then Go to Import tab
15. Import ‘all-db-dump-backup.sql’ file through the import option directly to server.
    Based on how many databases you have it will take some time.
16. If you have followed all the steps correctly you will get a success message “ Import has been successfully finished”.
17. After that run the following command mysql_upgrade in the Shell option.
18. Go ahead and check whether your site and databases are working properly or not.
19. If everything is working fine than you can delete the xampp-old file.

If you have followed my instructions then you should have a functioning XAMPP with no issues. If you do face any problem then please leave a comment and I will do my best to get back to you.  Enjoy!!

In this tutorial, i will share how to send Email from XAMPP (PHP). i use XAMPP 1.8.1 version .This has been tested by me and it worked.

Lets start:-
first always make a backup before changing any code in core/configuration files.
then

Edit your php.ini in - “xampp\php\php.ini”

Before Changes:- 
---------------------------
[mail function]
; For Win32 only.
; http://php.net/smtp
SMTP = localhost
; http://php.net/smtp-port
smtp_port = 25

; For Win32 only.
; http://php.net/sendmail-from
;sendmail_from = postmaster@localhost

; XAMPP IMPORTANT NOTE (1): If XAMPP is installed in a base directory with spaces (e.g. c:\program filesD:\xampp) fakemail and mailtodisk do not work correctly.
; XAMPP IMPORTANT NOTE (2): In this case please copy the sendmail or mailtodisk folder in your root folder (e.g. C:\sendmail) and use this for sendmail_path.

; XAMPP: Comment out this if you want to work with fakemail for forwarding to your mailbox (sendmail.exe in the sendmail folder)
;sendmail_path = "\"\XAMPP\sendmail\sendmail.exe\" -t"

After Changes :-
-----------------------
[mail function]
; For Win32 only.
; http://php.net/smtp
SMTP = smtp.gmail.com
; http://php.net/smtp-port
smtp_port = 587

; For Win32 only.
; http://php.net/sendmail-from
sendmail_from = yourgmailid@gmail.com

; XAMPP IMPORTANT NOTE (1): If XAMPP is installed in a base directory with spaces (e.g. c:\program filesD:\xampp) fakemail and mailtodisk do not work correctly.
; XAMPP IMPORTANT NOTE (2): In this case please copy the sendmail or mailtodisk folder in your root folder (e.g. C:\sendmail) and use this for sendmail_path.

; XAMPP: Comment out this if you want to work with fakemail for forwarding to your mailbox (sendmail.exe in the sendmail folder)
sendmail_path = "\"\XAMPP\sendmail\sendmail.exe\" -t"

now

Edit your sendmail.ini - “xampp\sendmail\sendmail.ini”
