Problem with echo on freshly installed Apache and PHP

[Rafal Z <rafzio4@xxxxx>]

Hallo,

  I',m new to PHP. I've installed Apache 2.0.59 and PHP 5.2. It's 
functionning, but all strings outputed with Echo shows on the same line, 
even if  I include a "\n" at then end of string. Example:

<?php
  Echo "string1";
  Echo "string2";
?>
results in: string1string2 in any browser.

The same result with the following modification:

<?php
  Echo "string1\n";
  Echo "string2";
?>

How could I change this behaviour

sincerely

Rafal Z
