New Comment:
I have a feeling, at this point, that while the new snapshot will stop
your segfault, it'll still not behave in the way you expect it to.
Try this seemingly unrelated script via your httpd server:
<?php
$fp = tmpfile();
fwrite($fp, "This is a test.\n");
rewind($fp);
fpassthru($fp);
fclose($fp);
?>
Ideally you should see "This is a test" in your browser... if
not....well... does it show an error?

pollita,
This script only breaks in http method, as the cli returns the
desired output(snafu). The Httpd child dies with a segfault. This
appears to only occur on the OS's listed on the main 4.3 distro of PHP
as well as alot of the snaps I've tried.
currently running FreeBSD 4.7-RELEASE #0: Wed Feb 12 19:59:59 GMT 2003
with php4.3.0 release (very stable).
thanks for your time, as I will try the current snap tomorrow.

Correction, the fix I referred to above didn't make it into the "Feb
13, 2003 22:30 GMT" snapshot, grab one that comes *after* that (i.e.
Feb 14, 2003 00:30 GMT)

I'm trying to understand the problem you're having, but I'm seeing some
slightly conflicting information so I'd like to figure out if I'm
reading you incorrectly...
Running the following script using the php CLI executable, what is the
*exact* output? (I'm just using ftp.kerneli.org as a known public ftp
server for the sake of example)
<?php
$fp = ftp_connect("ftp.kerneli.org");
var_dump($fp);
ftp_login($fp, "anonymous","[EMAIL PROTECTED]");
var_dump($fp);
var_dump(ftp_nlist($fp,"/"));
var_dump($fp);
?>
Don't take this request as demeaning or belittleing, I'm just trying to
approach this problem one step at a time.
Note: be sure to grab the latest snapshot (Dated after: Feb 13, 2003
21:00 GMT) before you try this out, I've just recently fixed a segfault
in the ftp extension which *may* be related.
