How can I stop from reading something?

[utahcon]

I have a script that returns the URL of the page the script is on.

When the URL is returned I want to scrape the content of the page.

The problem I am having is that my script is re-reading it self and thus starting an infinite loop.

What can I do to stop that?

You can use another get varible to see if you're getting here for the second time.

<?php
if (!isset($_GET['no_check'])
{
  $this_script="";//do your stuff here
  if (count($_GET)>0)
    $new = $this_script."&no_check=true";
  else
    $new = $this_script."?no_check=true";
  $content = file_get_contents($new);
}
?>

if ($theUrlToCheck == 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['PHP_SELF']) die("Can't check self.");
