Absolute url ...

PHP Code:


			
<textarea name="whatever">

<?include 'http://domain.com/your/file.php';?>

</textarea>

would show the HTML output of file.php , wheras

include '/home/user/www/your/file.php';

would show the PHP code.

DOH

Stuntboy just pointed out that the code I posted above would lead to an infinate loop and possible server death if you are trying to show HTML output of the current file !

that's not how I originally read your question but that appears to be what you actually meant ?

I am definately going to have to put a disclaimer in my sig somewhere

So working on an answer now if Stunt does not beat me to it

Here's how it's done client side, anway: (pulled from a favelet so the code might not be completely relevant)

Code:

function(){
  %20function%20htmlEscape(s){
   s=s.replace(/&/g,'&');
    s=s.replace(/>/g,'&gt;');
    s=s.replace(/</g,'&lt;');
    return%20s;
  }
%20x=window.open();
%20x.document.write(
  '<pre>'%20
  +%20htmlEscape('<html>\n'%20
    +%20document.documentElement.innerHTML%20
    +%20'\n</html>'));
%20x.document.close();%20})();

how about

PHP Code:


			
<?

if(!isset($_GET['sourced'])) {

echo '<textarea>';

include('http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'].'?sourced=yes');

echo '</textarea>';

}

?>

not sure about the ligitmacy of using querystrings from within an include call however.

EDIT: no more typo

that works a treat , just a typo here

if(!isset($_GET['sourced']))

but better a typo than infinate recursion
