file writing

LordOfTheBoards

I need to write text to a file for my guestbook. How can i make php to write at the begining of the file?????????? (Without deleting the rest of the file!)

Have a look at fopen

http://www.phpbuilder.com/manual/function.fopen.php

rw22

<?php
$filename = 'test.txt';
$somecontent = "new guestbook entry";
$handle = @fopen($filename, 'w')
        or die("file not found or isn't writable");
fwrite($handle, $somecontent);
fclose($handle);
?>

the 'w' argument puts the pointer at the start of the file, you can change that to 'w+' to point it to the end of the file.

That sounds good, but does "w" not delete the rows that have been entered before?

rw22

yes it does sorry, i think the best thing to do would be to read it all in then write it again

<?php
// now the only problem with this is, it accesses the file twice
// but i don't see any other way of doing it, please enlighten me.

$filename = 'test.txt';
$somecontent = "new guestbook entry";

// open file for reading
$handle = @fopen($filename, 'r')
	or die("file not found");

while ($line = @fgets($handle, 1024)) {
	// concatenate it
	$somecontent .= $line;
}

fclose($handle);

// open file for writing
$handle = @fopen($filename, 'w')
	or die("file not found or not writable");

// do the business
fwrite($handle, $somecontent);
fclose($handle);
?>
