Description:
------------
My environment:
----------------------------
Windows2000 Advanced Server
Apache 2.0.48
PHP 4.3.4
----------------------------

When i explore this php program(see aaa.php below) from IE, it tell me save file but output the correct content.
It is bizarrerie deeply.

But any output before "begin<" will run correctly(see bbb.php below).

The symbol "<" is become to a pipe? My guess only.
strange.

Reproduce code:
---------------
aaa.php
--------------------------
<?php
echo "begin<br>";
?>
--------------------------




bbb.php
--------------------------
<?php
echo "hello<br>";
echo "begin<br>";
?>
--------------------------


Expected result:
----------------
Output begin on IE like below
begin


Actual result:
--------------
aaa.php
---------------------
It tell me save file.
---------------------




bbb.php
------------------------------------------
It run the correct and output on IE:
hello
begin
------------------------------------------
