First question is -- why aren't you using a database for this
information? I would recommend sqlite (http://www.sqlite.org/)
Now that that's taken care of, if you're trying to color the text on
output, I would do it like this:
_______________________________________________________________________
<?php
$name = "nick"; //added for testing
$talk = "a message"; //added for testing
$NAMEFORMAT = '<font color="red">';
$MESSAGEFORMAT = '<font color="blue">';
$boardFile = "MessageBoard.txt";
$boardFileHandle = fopen($boardFile,'a') or die("can't open file");
/*
* Here we are going to write to the file, notice I added
another line that prints a comma. This will be useful
so that you can easily parse out and potentially
format the 2 elements at will
*/
fwrite($boardFileHandle, $name);
fwrite($boardFileHandle, ","); // added
fwrite($boardFileHandle, $talk);
fclose($boardFileHandle);
$boardFile = "MessageBoard.txt";
$boardFileHandle = fopen($boardFile,"r");
/* removed
$talkR = fread($boardFileHandle, filesize($boardFile));
*/
while (($data = fgetcsv($boardFileHandle, 1000, ",")) !== FALSE) {
/*
* put 1000byte buffer to $data, this also goes 1 line at a time.
*/
echo $NAMEFORMAT . $data[0] . "</font>"; // print the name
echo $MESSAGEFORMAT . $data[1]; // print the text
}
fclose($boardFileHandle);
?>
If you have any questions regarding the implementation I suggest the
following reading material:

Good luck!
