"Rob .... HELP (PHP)"

Hey Rob, do you know if and how it's possible to load the content of a .dat file into a PHP Variable???

The thing that Monkey_Man asked for, got me coding, and trying to make a simple ... v.simpl I should say, lol ... chat site.

Just all the msg's are coming up in the wrong order ... so if you (or anyone else here) know how to put the content of a .dat file into a PHP Variable, lets say $Chat_Text, I'd be greatful :o)

$fp = fopen($Chat_File, 'a'); # Add's to the end.
$fp = fopen($Chat_File, 'w'); # Overwrites.

Well, thats what my PHP Book tells me.

I was just wondering if there was a way of addiing to the begining???

Or, maybe putting the whole file into a Variable, adding the know line first and then replacing the variable in the text file, so the new line is put in first, then the old text is put back??? Get what I'm after???

I'm gonna start taking an interest in this PHP stuff. I've got a book on it, which is about 3 stone heavier then it was when I bought it, due to mass amounts of dust. Although, I might start reading it.....one day.....

Does fputs() append the file then? I though it completely overwrote it.

$Chat_File = "Chat_Text.dat";

$Text = trim($Text);

if (! empty($Text)) {
$fp = fopen($Chat_File, 'a');
$Time = date("g:ia");
fputs($fp, "\n$Username: $Text ($Time)
");
fclose($fp);
}


thats the part of the code that writes to the file. It includes the Username of the person, there Message and what time it was posted (in a 10:47pm format).



$Chat_File = "Chat_Text.dat";
$Lines = "50"; # How many lines of the chat should be displayed.

$fp = fopen($Chat_File, 'r');

for ($Counter = 1; $Counter <= $Lines; $Counter++) {
$Line = fgets($fp, 1024);
$Line = trim($Line);
print "$Line\n";
}

print "

---

\n";

fclose($fp);

is the code that reads the first 50 lines of the file, as I don't want every message posted, as that would make the page to big.

Thing is, the message is added to the bottom of the file each time, and I'd prefer it to be added to the top.... so the newer messages are shown :o). Right now, the oldest msg's display first, as they were added to the file first.


Any ideas?

Isn't the order in which the file is written part of your script? How are you writing to it anyway?

How do you mean exactly??

Er.. isn't that a problem with your script?

Some more help with those files things if you can :o)

I can do almost what I want .. got the mini-chat site working :o). But the new lines are added to the bottom of the foo.dat file, and I'd prefer them to be added to the top, so the newest lines are at the top, when the script reads the first 50 lines for the chat page ... the new ones are at the top, rather than the old.

Thanks :o)

Oh, er, it's the size of the file to read. I just realised this isn't probably what you want. Replace the 26 with:

filesize (foo.dat)

Yeah Rob .. your good :o)

But could I ask what the 26 bit means?
