[PHP-DEV] HTML generate from PHP code

[otto]

Hi I have some problem when I try to generate HTML file from PHP.

I have a "gen.php" and inside
-------------------------------------------------------------------
<? 
if (@$QUERY_STRING=="generate"){

   // I try on Linux and Win also 
   system("a.bat");
   // content of a.bat:
   // c:\php\php.exe -q <gen.php >index.htm

  
   //another try  system("/php/php.exe  < ".$DOCUMENT_ROOT.$PATH_INFO." >index.html ");


//   Header("Location:index.html");
   exit;
}


echo "hello world." ?>


when I run the "a.bat" from command line it's ok. I get index.html with content "hello 
world." 
But when I try direct from PHP /in browser url "gen.php?generate" / calling 
system("a.bat") I get this in index.html:
------------------------------------
X-Powered-By: PHP/4.1.1
Content-type: text/html
------------------------------------

any idea why is that, or workaround solution ?

thanks

 otto
