new lines in a text file

[t0mmy9]

hi i have a php script thats saving the contents of a textarea to a text file. the textarea is called "message" now heres the problem:

 

when someone presses enter to go to a new line in the textarea i want it to write to the text file a br instead of going to a new line. i tried nl2br

 

$stringData = nl2br($_POST['message']);

 

but this doesnt work either. my code is below. thanks for any help 

 

$myFile = "message.txt";
$fh = fopen($myFile, 'a');
$stringData = "\n";
fwrite($fh, $stringData);
$stringData = $txtid;
fwrite($fh, $stringData);
$stringData = nl2br($_POST['message']);
fwrite($fh, $stringData);
fclose($fh);

Why would you want to do that? Its better to store your data in its raw format.

because im making a shoutbox and i have more code that reverses the text making the newest entries first. but pressing enter in the text area messes this up

Create an array from the lines entered, write the serialized array to your file. When displaying, unserialize the line, and use the implode() function to put in the linebreaks.

 

<?php
$myFile = "message.txt";
$fh = fopen($myFile, 'a');
fwrite($fh, "\n$txtid\n");
$stringData = nl2br($_POST['message']);
fwrite($fh, serialize(explode("\n",$_POST['message']))."\n");
fclose($fh);
?>

thanks, when i entered

 

this is

a test

 

into the text box i got

 

a:2:{i:0;s:8:"this is ";i:1;s:6:"a test";} 

 

ill try and see what ive done wrong. this is the php that reverses it by the way

 

<?php

$text = file('message.txt');
$text= array_reverse($text);
foreach($text as $line) {
echo $line , "<br>";
}
?>

That is what the serialized array looks like.

 

When you read it back, unserialize it and display it:

<?php

$text = file('message.txt');
$text= array_reverse($text);
foreach($text as $line) {
echo implode('<br>',unserialize($line)) . "<br>";
}
?>

that seems to have done the job, thanks. $txtid contains html code, can you not use html with this method?

I have to leave for a few hours ... I'll post a solution when i come back.

ok no problem,

thanks for your help

 

edit:solved using this code:

 

$myFile = "message.txt";
$fh = fopen($myFile, 'a');
fwrite($fh, serialize(explode("\n",$_POST['message']))."\n");
fwrite($fh, serialize(explode("\n",$txtid))."\n");
fclose($fh);

 

the only problem was i wanted $txtid to be on the same line as the message but that doesnt really matter as long as this works. thanks again for your help
