There are many ways to insert a text file into PHP.  It's common to use
include() for this purpose.  include can be read about in the PHP 
manual
here (many examples exist):
  http://www.php.net/include
  include 'filename';   : Includes and evaluates the 
                          specified file.
The file is evaluated, so PHP code is evaluated as PHP code.  PHP code
is written within valid PHP tags, most commonly <?php ?>.
In the example below, we'll preserve whitespace in HTML by using 
<pre>.   
  <pre>
    <?php 
      include 'some/file.txt'; 
    ?>
  </pre>
Or, to open the file up into a variable, consider file().  file opens a
file as an array, each element being a line in that array.  file() is
sexy in that it opens files in one line of code :)  Also see 
fopen/fgets
and Curl.  
An example using file():
  <?php
    $filename = 'afile.txt';
    $lines = file($filename);
    // $lines is an array.  let's print the third line of afile.txt
    print $lines[2];
    // open file as an array, implode that array into a string 
    $file_string = implode('', file($filename));
    // print string, first converting newlines into <br \>'s
    print nl2br($file_string);
  ?>
   Read the PHP Manual for information regarding these functions.
     http://www.php.net/manual/
Another example.  Let's execute a Linux fortune and ouput the results 
to
an HTML page:
  <?php
    $fortune = `fortune`;
    print nl2br($fortune);
  ?>
  fyi: We used ``backticks`` to execute the fortune command on 
       the system.  Read about executing commands in php here:
         http://www.php.net/exec
         http://www.php.net/manual/en/language.operators.execution.php
Also keep in mind that different operating systems have different
"versions" of "newlines":
  \n    = unix
  \r\n  = windows
  \r    = mac
