This expression returns corrupted value:

  $host=gethostbyname($host);

This variant is good:

  $temp=gethostbyname($host);
  $host=$temp;

Even this:
  $host=$temp=gethostbyname($host);

Return two corrupted values for $temp and $host

I could not reproduce this with PHP 4.0.3/OpenBSD, PHP 4.0.6/Linux, PHP 4.0.7RC2/Linux or latest CVS/Linux...

Can you please post the whole script, and possible can you show us the failing script on a webserver?

Also tried it on php 4.0.8dev on FreeBSD 4.3. Works fine too.

Seems that I can't reproduce this on simple scripts too.
I've stable errors on my complex site. This script uses two nested functions with includes. In one include I'm used gethostname() and it broke my variable.

So, I'm closing this bug, because I can't reproduce all of my code.

Oleg Khimich.
