Text file Reverse reading

[Faisal Shah]

Hi,

Well, My name is Faisal, You might saw as my ID. I got into php before a few months...

I need help.. I am trying to read a file that is .txt format..
Line by Line, Reverse action..

I mean from Last to 1st line.. I really don't care.. I can write them on my memory of php.. No matter..

Can you advice me how can I do this work?

I mean if i can do from an array.. So can you guide me how? I am not so good in arrays ;)

Help please...

Waiting for answer!

FAISAL!

As I see it, your text file (,txt) does not contain any newline's (\n) or carriage return chars (\r) or a combination of these.

A 'normal' text file has this at the end of each line, so when you read it in the end of each text line can be found and so the text file can be split in different lines.

Since you (as I image) do not have that, then you must determine what is the end (or beginning) of each new shoutbox entry text line. Knowing that you can spolit it up in different text lines and sort it, newest on top.

So questions are: (a) why does you text line not have an end (newline, carriage return or both) and (b) how else can we determine the beginning or end of a text line.

fclose($f_handle);
 
echo "<i>Message Sent....</i>";
@include('form.html');
}
}else
{
@include('form.html');
}
?>
 

Can you please finally fix that \n thing for new line??

Thanks..It will help me to finish this shoutbox and to learn as well ;)

Since you do not write the newline, write it to your output text file like this[php]fwrite($f_handl e,$full_message .$new_line."\n" );[/php]Then you can read the file as I showed earlier.
