How can I run a remote web script or page from php?

You can query any URL from php , and pull in the results.  This can be useful for triggering a script remotely, or loading specifc html / xml content you want to parse somehow.  Here's a code snippet to run a remote URL:

print "Running remote URL:\n";
  $file = fopen (http://[remote url goes here], "r");
  while (!feof ($file)) {
   $line = fgets ($file, 1024);
   print "$line\n";
  }
  fclose($file);

This just prints out the lines retrieved, but you could parse them in another way.  I used this snippet to trigger a remote script, so I wasn't doing anything with the results.
