Hello,

I'm writing a news system and it's moving along quite well. I'm at the point now where I'm writing items to a flat file (please no database suggestions) and my only gripe about what it does is that it write newest entries to the bottom of the file. I would like someone to simply modify the code below to write to the top of the file, and have existing lines follow afterwards. NOTE: It is important that previous items keep their same order. Please use efficient code, and thanks in advance.


THE CODE:

<?
include("oauth/authorize.php");
?>
<?
$template = implode('',file('news.tmpl'));
$template = str_replace ("{InsertNews}", $newscontent, $template);
$template = str_replace ("{InsertTitle}", $newstitle, $template);
$template = str_replace ("{InsertDateTime}", $datetime, $template);
$template = str_replace ("{InsertName}", $name, $template);

$fp = fopen ("C:/Inetpub/Omniformity.com/oNews/news.txt", "a");
fwrite($fp,"".stripslashes($template)."<br><br>\r\n");
?>

// Read the original file into a simple array.

// Create a new file.
$fp = fopen ("C:/Inetpub/Omniformity.com/oNews/news.txt", "w");

// Write the new line to the new file.
fwrite($fp,"".stripslashes($template)."<br><br>\r\n");

// Write the original lines to the new file.
fwrite($fp,$origfile);

// Close the new file.
fclose($fp);
?>

Same as RQuadling but correction, $origfile is an array

<?
   include("oauth/authorize.php");
?>
<?
  $template = implode('',file('news.tmpl'));
  $template = str_replace ("{InsertNews}", $newscontent, $template);
  $template = str_replace ("{InsertTitle}", $newstitle, $template);
  $template = str_replace ("{InsertDateTime}", $datetime, $template);
  $template = str_replace ("{InsertName}", $name, $template);

  $origfile = file("C:/Inetpub/Omniformity.com/oNews/news.txt");

  $fp = fopen ("C:/Inetpub/Omniformity.com/oNews/news.txt", "w");
   fwrite($fp,"".stripslashes($template)."<br><br>\r\n");

   for($i=0;$i<count($origfile);$i++)
        fwrite($fp,$origfile[$i]);

   fclose($fp);
?>

I've just tested it works, and it's better, less code

That's a LOT better!

The file command will read the lines into an array and keep the newline stuff (I wondered about that, RTFM).

The join will create a single variable of the array of the lines with no extra space between them!

Clever!
