Now I found two solutions for resolving this issue,and both of them has been worked very well:

Solution One:

First find the exact absolute path to your tmp folder by using this trick:

Create a PHP file in your website root,for example path.php

Place this snippet of code in the file and hit the save button

<?php
$path = getcwd();
echo "Your Absolute Path is: ";
echo $path;
?>

Navigate to yourdomain.com/path.php in your browser

From now on:

1. Login to your Joomla Administartor panel.
2. Go to Global Configuration
3. Click on the "Server" tab
4. Change the path to the "Absolute Path(you've just found)"/tmp

5. Insert this line of code in your .htaccess file: php_value open_basedir NULL

   This solution has been worked very well for me,and it's doesn't deal with any Joomla's core file hacking.

Solution Two:

1. Login to your Joomla Administartor panel.
2. Go to Global Configuration
3. Click no the "Server" tab
4. Change the path from /public_html/tmp to just tmp
5. Login to control Panel(CPanel),(Or you can use a FTP account for this purpose)
6. Open File Manager (if you are using FTP,this step must be skipped)
7. Open Folder "libraries"
8. Open Folder "joomla"
9. Open Folder "filesystem"
10. Right Click on "folder.php" and click Edit.
11. Look for the line, (search = obd): $obd = ini_get('open_basedir'); Comment out that line with // at the beginning so it becomes://$obd = ini_get('open_basedir');
12. Save and Close.
