hello,
I'm writing a socket approach to send email directly via an SMTP server
(since some hosts block sendmail trough php due to abuse). Now, I have
the code, attached below:
I have cut it down slightly so it would still be readable though. I'm
very sure that none of the stuff I removed actually matters in the
problem though (mostly error chechking, logging, debug stuff, etc).
Ok, back to the problem. If I reread my log, I see the following "output":
S: 220 server -- Server ESMTP (iPlanet Messaging Server 5.2)
C: HELO ip
S:
C: MAIL FROM: <[EMAIL PROTECTED]>
S: 250 server OK, server2 [ip].
C: RCPT TO: <[EMAIL PROTECTED]>
S:
C: RSET
Now, obviously, the server sends something back (I checked, manually,
using telnet). So, I figured that the socket_read(socket, size,
PHP_NORMAL_READ) was causing the problem. So I switched over to
PHP_BINARY_READ to make sure I didn't miss anything (because it broke
off eg. midways). So... after I changed that, I suddenly started getting
these errors:
Warning: socket_read() unable to read from socket [11]: Resource
temporarily unavailable in /home/me/scripts/mail.php on line 27
This goes for each attempt to read (even the first). I'm stumped... and
really don't know how to proceed now...
Does anyone have any clues?
very appreciated,
- Tul
P.S. see attached, code:
<?php
class socket_SMTP {
var $socket = null;
function connect($host, $port, $user, $pass) {
$this->socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if ($this->socket < 0) {
exit("socket_create() failed: reason: " .
socket_strerror($this->socket) . "\n");
}
$res = socket_connect($this->socket, gethostbyname($host),
$port);
if(false === $res) {
echo 'No connection';
return false;
}
socket_set_nonblock($this->socket);
$this->get();
$this->send('HELO '.'my-servers-ip-addy-goes-here');
$this->get(); // ignore res
}
function send($cmd) {
socket_write($this->connection, $cmd."\r\n",
strlen($cmd."\r\n"));
}
function get() {
$ret = socket_read($this->connection, 1024, PHP_BINARY_READ);
return $ret;
}
function sendMessage($from, $to, $message, $headers) {
$headers = $this->safeData($headers);
$message = $this->safeData($message);
$this->send('MAIL FROM: <'.$from.'>');
$this->send('RCPT TO: <'.$to.'>');
$this->send('DATA');
$this->send($headers);
$this->send(''); // CRLF to distinguish between headers and
message
$this->send($message);
$this->send('.');
// sent message
return true;
}
function disconnect() {
$this->send('QUIT');
socket_close($this->socket);
}
}
$mail = new socket_SMTP();
$mail->connect('mail.server.com', '25', 'username', 'password');
$mail->sendMessage('[EMAIL PROTECTED]', '[EMAIL PROTECTED]', 'Test message',
'Subject: whatever-test-mail'."\r\n");

You have to catch the 'not ready' error something like this:
(The error code was under windows)
function get(){
$ret = '';
while(1){
$sbuf = @socket_read($this->connection, 1024, PHP_BINARY_READ);
if(false === $sbuf){
$error = socket_last_error($this->connection);
if($error != 10035){
echo "msgsock read() failed: reason: " .$error.' '. socket_strerror
(socket_last_error($this->connection)) . "\n";
return;//socket not happy
}
}else{
$buf_read = strlen($sbuf);
if($buf_read === 0) break; // end of text
$ret .= $sbuf;
}
}
return $ret;
}

hello,
thank you for the help, but I've tried your code, and it returns the
exact same thing :( the error #11 temporarily unavailable. If I remove
non-blocking, or change the error to ignore to 11 (10035 in your code
example) it simply "hangs" doing nothing *at all*...
I'm stumped; really.. thank you for trying though :)

All:
Firstly, sorry if this is the wrong list. There are thousands of forums
and PHP5 related MLs, but nothing FBSD specific.
Second, I wouldn't post if this wasn't happening on two completely
different FBSD boxes.
For whatever reason, the php4 and php5 from FreeBSD ports refuses to
properly configure SSL/TLS support for the LDAP module.
This breaks the TLS/SSL functionality in net/phpldapadmin and
sysutils/ldap-account-manager (CC'ing maintainers)
I've got two current i386/RELENG_5_3 boxes. Both with Apache
apache-2.0.54_2 and openldap-client-2.2.27.
The ldap client binaries are linked to SSL fine and can talk both ldaps://
and Start_TLS over ldap://. That's out of the question.
One with php4-4.4.0, one with php5-5.0.3_2 (see below). Both have the
LDAP and SSL php extension modules installed:
$ egrep -i "ldap|ssl" /usr/local/etc/php/extensions.ini
extension=openssl.so
extension=ldap.so
The php4 box's ldap module is linked to OpenSSL:
# ldd /usr/local/lib/php/20020429/ldap.so
/usr/local/lib/php/20020429/ldap.so:
libldap-2.2.so.7 => /usr/local/lib/libldap-2.2.so.7 (0x28174000)
liblber-2.2.so.7 => /usr/local/lib/liblber-2.2.so.7 (0x281a7000)
libcrypto.so.3 => /lib/libcrypto.so.3 (0x281b4000)
libssl.so.3 => /usr/lib/libssl.so.3 (0x282c8000)
The php5 box is as well:
$ ldd /usr/local/lib/php/20041030/ldap.so
/usr/local/lib/php/20041030/ldap.so:
libldap-2.2.so.7 => /usr/local/lib/libldap-2.2.so.7 (0x28173000)
liblber-2.2.so.7 => /usr/local/lib/liblber-2.2.so.7 (0x281a6000)
libcrypto.so.3 => /lib/libcrypto.so.3 (0x281b3000)
libssl.so.3 => /usr/lib/libssl.so.3 (0x282c7000)
The problem is that ldap_start_tls() is an unregistered/invalid function.
When i run the functions.php at
http://www.sitepoint.com/article/php-command-line-2
ldap_start_tls() isn't listed on either machine (see below). The only
reference to the problem I've been able to find is a PR:
http://www.freebsd.org/cgi/query-pr.cgi?pr=72275
.....but this only relates to PHP4. I don't know why *GRRR*, but this PR
was closed without a fix ever being commited or any remarks! Anyway, I
tried the proposed solution on the PHP4 machine. I removed the OpenSSL
shared extension, export WITH_OPENSSL=true, recompiled php4 CLI/MOD with
SSL static. Removed the SSL module from extensions.ini. Same problem.
The only possible localized problem I can see is my my predecessor placed:
PHP_EXT_INC=openssl
in php.conf. I've tried rebuilding with and without that to no avail.
Anyway, I'm going to start looking into this tonight. Any thoughts would
be appreciated. I'll open a PR when I track down the problem.
TIA,

Can't you just build from the PHP tarball instead? Seems like a messed
up port to me. I use FreeBSD all day, every day and haven't seen this
problem. But I also don't use the ports.

Hi there!
Soundex works with diffrent kind of pronounciation... but does it work with
Swedish language?
Anyone have experience of this???

My understanding is that soundex was developed by several mathemeticians
at MIT in the 1950's. The idea was to create a way for similar sounding
family names to be grouped together reguardless of how they might be
spelled, and since english was the language their world spoke, the
algorithm tends to work best with names found in the northeastern United
States. I believe there are different variants on the algorithm, but
they should produce the same binary number for names that sound the
same. i.e. Smith and Smythe should produce the same number, or if not
numbers very close to one another. I would expect poor results with the
Swedish language, perhaps if the mathemeticians had come from Minnesota.
I have personally seen it produce very bad results from Oriental and
Italian names.

Hi,
I have an htaccess file and I want to create users and password with a php

Hello, all -
This is a question that could depend on a completely different (yet,
relayed) subject, so I'm sending this email to both php-general@ and
[EMAIL PROTECTED] I thank you in advance for your understanding.
I am currently generating some images on the fly using some of PHP's
image generation and rendering functions. I'm having loads of success,
and like the results that I see.
What I'd like this script to do is, to create symlinks to the origional
image, and then when the script is done running, the symlinks are
deleted. Basically trying to make it so that the origional image is not
known to the client or browser.
So I'm taking, say, image1.jpg. I'm creating a symlink via:
$linkname = md5(rand());
or something similar. I'd then like to return $linkname to the client
or browser. Then, when the browser has completed rendering the page to
the client or browser, the symlink is then deleted.
What I'm curious as to right now is if I do this, the client will see
the link to $linkname via HTML's "img src=" specification. What happens
if this is sent to the client or browser, and the symlink is deleted
immediately after the name is sent to the client or browser? Would the
web server (in this case, Apache) cache the image in memory until the
client has downloaded said image, and then delete it from memory when
the page is done rendering or being sent? Will PHP totally disregard
the web server's request to "hold" the image, and render nothing to the
browser? This is something I'm confused about.
Thanks!

I need a way of setting the session_vars specific to a users browser window
for the case of the user having multiple windows open for the same php
session. Is this possible in php?
I know you can pickup the window id via "self" in JavaScript but I can't see
how you can link this back to the server side session vars. I can't find a
PHP var that has this information.
Thanks
Chris

This will not work. $_SELF isn't even a defined variable, unless you
defined it yourself.
PHP works on the server, *before* anything is sent on the client, so it
has no way to know client-side things like what browser window you are in.
You could place the value in a hidden form field with JS and then post
back to the server, but something tells me you may be approaching the
problem in the wrong way. Without more details I can't suggest
alternatives, though.

My problem is that I have a database system where I have a form to define a
search pattern of the database
which gets placed in session_vars. The user then can use a whole bunch of
php pages to work with this search criteria.
My problem is that if the user does "file new window" in the browser s/he
can then define a new search pattern which
would change the session_vars behind the back of the other window and cause
havoc on that window. I really don't want to
put the search criteria as part of the URI between all these pages and use
GET to pull the data off as the user
could fiddle with the line and again cause problems. It probably would be
nice to be able to stop "file new window"
from working but I have not found a way of doing this.

Hello *,
for an half hour I was at a new customer and they run apache 1.3 as
root on am IntranetServer because they need to admin there Fileserver
via php.
Now some problems:
1) They use exec("mcrypt ....") to generate UNIX passwords for
/etc/shadow and I like to know, how I can create suitable md5
passwords for it from php.
2) I like to run apache as www-data and not as root. How I must
setup php/apache that I can do root-stuff because I need to run
exec("useradd -c $WA_COMMENT -d $WA_HOME_DIR \
-e $WA_EXPIRE_DATE -f $WA_INACTIVE_TIME \
-g $WA_INITIAL_GROUP -G $WA_GROUPS \
-m -k $WA_SKELETON_DIR -s $WA_SHELL \
-u $WA_UID -p $WA_PASS_MCRYPT $WA_LOGIN")
Thanks and nice wekend
Michelle
