WordPress Unpacker Script

Downloading WordPress, unzipping it on your computer, then using FTP to send it to your website hosting environment is slow. This whole process, even with a very fast internet connection, can take 10 minutes. If you’ve got a slow internet connection, you might as well go to lunch.

So I wrote a PHP script to handle all of this. All I need to do is use FTP to send a single file to the website hosting environment, then use my browser to run it. The whole process might take 30 seconds.

Update 3/25/2014: Not working on Godaddy. Should I be surprised? I’ll see what I can do about this later.

Update 3/26/2014: Now working on Godaddy. Issue was related to PHP version and lack of support for __DIR__.

			copy( $target, $destination );
		}
	}

	// Close the zip
	$zip->close();

	// Delete the zip file
	unlink( $wp_zip );

	// Display confirmation that process completed
	echo 'Process Completed';
}
else
{
	// FAIL!
	echo 'FAIL';
}

Make sure to remove the script from your website hosting environment after your run it.
