going to the ToP^

[Anon]

um, i cant find out how to get posts to go to the top of a text file... when i use r+ or r it just deletes some then writes it. how an i do this?like is there a way that i can make it recognize how many times i have posted and make it write to a file name for it? ex.: file$postnumerber.txt? um please help.

what you could do is something like this..

$currentcontent = implode ("", file ("example.txt"));
$newcontent = "blah, what will be at top";
$totalcontent = $newcontent."\n".$currentcontent;

Dragging out my old Microsoft C Bible :

the "r" switch only opens the file for reading, so you can't write to the file.

the "r+" switch opens the file for r/w, but it appears you will overwrite the file, starting from the beginning, unless you position with an fseek() to the end of the file (similiar to using a+ mode).

This is an old word processing situation. You must save the file in its entirety before you can alter it in any way, and you'd better know where every single character is in the file.

the way I posted will also work.
although I did forget the part about opening the file and all hehe.
your fopen command should be placed after the $oldcontents=implode(blahblah...);
your fopen command should look like
fopen($filename, "w");

so to clear this all up... the entire thing should look something like:

$filename="example.txt";
$oldcontents=implode("", file($filename));
$newcontents="the new stuff to be at top";
$totcontents=$newcontents."\n".$oldcontents;

$fopen($filename, "w");
$fwrite($filename, $totcontents);
$fclose($filename);

make sense?

P.S. Stinger,
'r' - Open for reading only; place the file pointer at the beginning of the file.

'r+' - Open for reading and writing; place the file pointer at the beginning of the file.

'w' - Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.

'w+' - Open for reading and writing; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.

'a' - Open for writing only; place the file pointer at the end of the file. If the file does not exist, attempt to create it.

'a+' - Open for reading and writing; place the file pointer at the end of the file. If the file does not exist, attempt to create it.

From the manual:

"implode -- Join array elements with a string"

I didn't see any array in your example to implode. How did you get the entire file contents into an array? I think there is a function to do this, right?

[Anon]

$oldcontents=implode("", file($filename));

look again hehe
I am imploding file($filename);
file($filename); loads each line of $filename into an index in an array.
