Output has an empty line

[eluser]stanleyxu[/eluser]
Hello,

I define a function in my own controller. The output contains an empty line at the beginning.

For instance:

Code:

class Myclass extends Controller {
  function test() {
    echo 'Hello';
  }
}

The output will be

Code:

'

Hello'

This empty line at beginning should not appear. My function tries to generate an image. But now the output contains an empty line at the beginning. The image is no longer recongizable.


Any comments ?

This is one very important reason why Zend discourages use of the closing PHP tag.

Thanks for the note. I really did not know, I can save the closing tag ("?>") at all.
