My code works but i need it to do something. the script add the data at the end of the document. what i would like is that, i want it to write at the top of the document without overwrite the actual document.

 

 

<?php




$text = $_GET['text'];
$act = $_GET['do'];
if ($act == "rst") {
$fp = fopen('log.txt', 'w+');
fwrite($fp, '');
fclose($fp);
}


else {


if ($act == "sub") {


$text = "<img src='images/say.png' height='20px'/><a href='#'>ZulfadlyAshBurn</a> " . $text . "<p style='float:right; color:#C0C0C0' align='right'><img ALIGN=ABSMIDDLE src='images/clock.png' height='20px'> " . date("d/m/y : H:i:s", time())  . "</img></p><hr color='#F0F0F0' width='100%' size='1'/>";


$fp = fopen('log.txt', 'a+');
fwrite($fp, $text);
fclose($fp);
readfile('log.txt');
}


else {


if ($act == "setp") {


$text = "<img src='images/set.png' height='20px'/><a href='#'>ZulfadlyAshBurn</a> " . $text. "<hr color='#F0F0F0' width='100%' size='1'/>";


$fp = fopen('log.txt', 'a+');
fwrite($fp, $text);
fclose($fp);
readfile('log.txt');
}
else {
echo "<title>Unauthorised</title>You are not authorised to view this page! Please leave.";
}
}
}


?>

Here's a small script to read and write to a text file.

a+ is append and w is write new

 

<?php
//read a file
$my_file = "filename.txt";
if (file_exists($my_file)) {
$data = file($my_file);
$total = count($data);
echo "<br />Total lines: $total<br />";
foreach ($data as $line) {
$line = trim($line);
echo "$line<br />";
}

//add a new line to end
$write = fopen($my_file, 'a+');
$message = "got a new line here\r\n";
fputs($write, $message);
fclose($write);

/*note the w, this will overwrite the entire contents
$write = fopen($my_file, 'w');
$message = "I just added this line and overwrote the file\r\n";
fputs($write, $message);
fclose($write);
*/

} else {
echo "No $my_file to display";
}
?>

HAHA. No Prob. Thanks alot. It work great

[ZulfadlyAshBurn]

sorry, my bad. somehow, it doesnt work or it just add to the end of doc.

 

$fp = fopen('log.txt', 'a+');
rewind($fp);
fwrite($fp, $text);
fclose($fp);
readfile('log.txt');

Yeah sorry again, that appends but overwrites.

 

To really append at the beginning with no mess ups, you have to first get all the contents of the file (big files would consume lots of memory), save it something like temp.txt, clear the original file, put the new contents and append the saved contents at the end.

 

You can't just reverse the data when call upon the file?
