如何在浏览器中打印php文件（源代码）？

Question

How can I print a php file (source) in the browser without the php tags at the start and at the end?

So if my php file looks like this:

<?php
  if( true ){ 
    echo 'hello world';
  }
?>

And in another file I want to load that file and echo the if statement so from the line 2 to 4, but not loosing the tabbing.

I have tried: fgets() and file_get_content() functions, butI can only echo an non-tabbed data.

Is there a method for this problem? or I have to write code for tabbing the source?

This should work for you:

(Here I get all lines into an array with file() . Then I cut out the first and the last line with array_slice() . After this I simply loop through the array an print it)

<?php

    $lines = file("file.php");
    $lines = array_slice($lines, 1, count($lines)-2);

    foreach($lines as $line)
        echo str_replace(" ", "&nbsp;", $line) . "<br>";

?>

output:

  if( true ){  
    echo 'hello world'; 
  }
