First of all, I'm running PHP 4.1.2 as a script with Apache 1.3 on Windows XP Pro.  I'm only using gd2 and gettext as modules.

To illustrate what is happening to me right now, suppose I got an array $authors from a database, each containing another array with two key-value pairs (aid, author.)

Now, in order to print it out, I use:

function listArticleAuthors() {
  global $authors;
  if ($authors)
    foreach($authors as $a)
      echo "<li><a href='author.php?id=" .
      $a[aid] . "'>" . $a[name] . "</a></li>";
  return;
}

I have three or four other functions somewhat similar to this one, which iterate through other arrays.  The arrays are all very small (no more than half a dozen elements each.)

Now, there's no problem when I run the code below *outside* the function.  There is also no problem when I'm calling only a couple of these functions.

But when I call all the functions, or the same function more than once, the PHP process inexplicably goes zombie and the page stops loading.  It's only when I kill the process using Task Manager that the page resumes loading as normal.  There's no lost output, there is no system slowdown.

I don't think I'm pushing it too hard: the PHP process just stays running using very little resources (0% processor, 2 or 3 megs.)  Any idea about what could be happening?

Cheers and thanks!
