I've got a .php file with javascript, php, and html. I want to include a button/link to view the source of the entire file "pretty printed", but I can't seem to get anything to work. What is the best way to do this?

Some combinations of Apache/PHP are configured so that files ending in .phps aren't run as PHP, but instead, highlighted and prettified.

If you simply want to display the code of the file, you can call this function:

function echoFile($pathToFile){

  $handle   = fopen($pathToFile, "r");
  $contents = fread($handle, filesize($pathToFile));
  fclose($handle);
  $contents = str_replace("<", "&lt;", $contents);
  $contents = str_replace(">", "&gt;", $contents);
  echo "<pre>$contents</pre>";
}

So, if you want to display myPhpFile.php, just do 

echoFile("myPhpFile.php");

As far as making it prettified, follow the link that was commented.

I'd recommend also replacing & with &amp; to avoid the character being parsed as an entity. Also, do this before replacing < and > to avoid re-escaping the escaped angle brackets.
