Flushing the output buffer doesn’t works in PHP sometimes no matter what you do. I had this code which would never work on my server but would perfectly fine on localhost. This was the code.

include('common.php');

ob_implicit_flush();
for($i=0;$i<10;$i++) {
      echo $i;

To install them, type the following in terminal:

It just commented out few lines of codes and voila! I was able to send my first email.

Those who are in need of a email library could use this simple library separately. I’ll guide you through the whole process step by step.

First thing you need to do is copy the Email.php from system/libraries folder and place it inside your script. Then use your favorite IDE to edit these lines:

I had some hard-drive free space constraints and bought a new 500GB one. Now I wanted to transfer/migrate my current installation to the new hard-drive. Here’s how to do it.
