[Toolserver-l] protip: i/o and infinite loops in php

never do this:

do {
  $x = file_get_contents("http://www.example.com/");
} while ($x === false);

or this:

while (!feof($f)) {
  $x .= fgets($f);
}

why not: because if the i/o fails, your script will run forever, using
100% cpu, doing nothing.

instead, add error checking, and exit if there's a problem:

if (($x = file_get_contents("http://www.example.com") === false) {
  echo "shit happened\n";
  exit;
}

please make sure none of your scripts have this problem, because they
cause issues for all users on the toolserver.
