php write to txt file???

bcbirkhauser

I'm trying to write to a text file, but I want to add the text to the top of the file and leave the rest still in the txt file. I don't want it to append to the bottom of the file, nor erase what's already there. this is what i have so far in my php file.
<?php
$fn = "data.txt";
$file = fopen($fn, "a+");
$size = filesize($fn);

if($POST['update']) fwrite($file, $POST['update']);

$text = fread($file, $size);
fclose($file);
?>
any suggestions?

$file = "data.txt";

$contents = file_get_contents($file);
$contents = $_POST['update'] . $contents;
$fp = fopen($file, 'w+');
fwrite($fp, $contents);
fclose($fp);

that works, exactly how I wanted. However I have one more stipulation. My text file is loaded into flash. so in order for that to happen, i have the words "text=" at the beginning of my txt file, which tells is the variable i load into flash. is there a way to put my updated text, using the php file after the words "text=" but before everything else?

$contents = 'text=' . $_POST['update'] . $contents;

that works, but my text file looks like this:
text= whatever text i update here text= my old text here
it just adds "text=", which isn't what i'm trying to do. I want to specify where to write, so it begins writing after "text=". is that possible?

drew010

$contents = 'text=' . $_POST['update'] . str_replace('text=', '', $contents);

This is almost perfect for me to ask my question-

I'm in pretty much the exact same situation- writing a text file for flash. I've got a screen where a user can enter in text and the form writes the text file from that input.

I want to enable my user to use carriage returns and to replace them with 's, because in flash the variable must be a string on a single line or else the line breaks are much larger, like the equivalent of doing two or three 's. So I went-

$textAreaStr = str_replace(Chr(13), " ", $textAreaStr); but instead of

blah blah blah blah blah

I got

blah blah blah 
blah blah

etc. How do I actually get rid of the carriage returns? Any ideas?

I'm going to go ahead and do a new post for this question.
