1. Visit the Codeigniter bitbucket (source code repository) site at https://bitbucket.org/ellislab/codeigniter/.
2. Hover over the icon and choose .zip
3. You will now be prompted by your browser to save the file onto your system.
4. Navigate to this file and use an Unzip utility to extract these files into a path accessible by your web server. (Note: If your webserver exists on a different machine, upload the unzipped files via FTP to your web host)
5. Open your browser and type in the URL to the Codeigniter path!

echo "<script language=javascript>myfunction();</script>";

I finally decided to investigate the issue and did a Google search for the problem. Most websites recommend altering a couple of settings in the about:configFirefox configuration page. However, these issues did not address the root of the problem and simply gave a non-ideal workaround. However, searching for the solution gave me the idea that perhaps it is one of my FF Plugins that is causing the problem. So I one-by-one, I disabled my plugins and let FireFox run for several hours while I observed the memory usage and voila! I found the culprit…FireBug 1.3.3! After disabling this plugin, I have been running Firefox memory leak free!

I hope this article helps those that are suffering from the same issue!

$hostname = "target_host";
$username = "root";
$password = "password";
$sourceFile = "test.txt";
$targetFile = "/root/test.txt";
$connection = ssh2_connect($hostname, 22);
ssh2_auth_password($connection, $username, $password)
ssh2_scp_send($connection, $sourceFile, $targetFile, 0777);

This is a very simple script that does 3 things:

1) Connect to the host target_host

2) Authenticate with the host using root as the username and password for the password.

3) Copy the local file test.txt to /root/test.txt on the target machine.
Note:  0777 sets the permission on the target file so that it can be read/write/executed by anyone.
