There's two parts to that.  Start with reading the file and outputting it exactly as it is.  Then add a filter that outputs only lines with >> at the front.

 

If you have a go at it then we can help when you get stuck.

<?php

$myFile = "master.txt";

$fh = fopen($myFile, 'r');

$theData = fread($fh,filesize($myFile));

fclose($fh);

//echo $theData;

what kind of php filtering function i should use here?

...

?>

It's probably easier if you read the file line by line, with a loop like this:

 

while ($line = fgets($fh)) {
  if (strpos($line, '>>') === 0) {
     # This is a matching line
  }
}
