Operating system: WinXP, SuSe 9.2 (PHP:4.3...)
PHP version: 5.0.3
PHP Bug Type: Output Control
Bug description: Output Buffering Bug
Description:
------------
i'm using ob_start() with a callback function; internally in it i use
$res=var_export($var, TRUE) function but got an error:
[11-Feb-2005 08:28:15] PHP Fatal error: var_export() [<a
href='ref.outcontrol'>ref.outcontrol</a>]: Cannot use output buffering in
output buffering display handlers in E:\htdocs\index.php on line XXX
Reproduce code:
---------------
<?php
ob_start("my_shutdown_function");
function my_shutdown_function($buffer){
$var=headers_list();
$res=var_export($var, TRUE);
return($res);
}
print("something...");
?>
Expected result:
----------------
the "dump" of all sent headers instead of string "something..."
Actual result:
--------------
"PHP Fatal error..."
Comment: this error actually must be when i call var_dump() or
var_export($var, FALSE) in output buffering handler.
