Write to top of txt file

[Anon]

I want people to submit their names and comment in my chatter box form, the script I have writes the new comments at the bottom of the text file where all the comments are stored. How can I write the new comments at the top of the txt file??

You can't. Instead, you have to rewrite the entire text file, starting with the new line and then appending all the previous content after it. Don't forget to lock the file during the update process, unless you like nasty surprises. Or consider changing the storage to use a dbms.

This is the current code im using for my post action:

<?
$date = date("m.d.y");
$message = "<b>$nick :: $date</b> -$msg<br>";
$fp = fopen ("messages.txt", "a");
fwrite ($fp, $message);
fclose ($fp);
?>

nick=their name
msg=the comments they left

Please use my code in telling me what to do, thanks!

i have this variable $filename which i want to give the value of "message.txt", like this..

$filename = "message.txt"

So now $filename represents message.txt and all of its contents...is that legal? Im new at php and i dont know if im declaring it right. please help

You have to write 'as append' to a file, and then read the file into an array with each line as an element of this array. Then simply display this array backwards.

You can find all this in the php-manual.

This is simple, take everything from the text file, put it into a string, then write the new message, then "paste" the string in after it. Here's the code:

$fcontents = join ( '', file ( "messages.txt"));
$fp = fopen ("messages.txt", "w");
fwrite ($fp, "$message\n");
fwrite ($fp, $fcontents);
fclose ($fp);
