[PHP] Is the php sockets extension experimental?
Hello, in the packet description of the php5-sockets in the SuSE Linux Enterprise Server 11 (SLES11) is the package php5-sockets in the additional SDK available, but marked as experimental (see below). Is this the true, where can I find this Information, or is this only a historical relic? Are there differences in this extension between PHP 5.2.x, 5.3.x and 5.4? Can I rely on this the extension for a productive environment? Thanks in advance, Meike == ~ # zypper info php5-sockets Refreshing service 'SMT-http_delds01_entiretec_com'. Loading repository data...

Re: [PHP] PHP sockets enabled but socket_create() gives an error call to undefined function
We added the extension=sockets.so to php.ini but it didn't work. However,
the problem was there was no sockets.so extension anywhere to be found.
i searched if I could install or add sockets.so extension. Couldn't find
anything.
Still looking for it.
Thank you for all the help.

However, I found that Linux machine's php.ini doesn't include
sockets.so and
sockets work fine on it but don't work on the Solaris machine.
Is it required to be included only in Solaris?

check phpinfo() to see if the sockets have been activated in the

Since you complied with --enable-sockets, you shouldn't even need
sockets.so to be dynamically loaded. But at this point, it is
something that
I would try anyway.
Add:
extension=sockets.so
in your php.ini file just to see if it brings the function to light.
Your Linux installs I am sure were compiled with it in it. Especially
if it
is a dist package.
The absence of the function is telling me that PHP is not compiled
with
--enable-sockets. If it was compiled in properly, you would be getting
different errors. I am not saying that you didn't do it. Something may
have
happened in

probly there is no need to, however you should understand the difference
between adding support for and enabling an extension.
compiling w/ --enable only makes the extension available. the extension is
not enabled unless you do what Nick has been saying. (there are other
options as well actually). there may be other files aside from php.ini
where this setting is made, depending on how the OS vendors package up the
code. for example using mac ports, i just installed sockets and now have a
shiny new sockets.ini file.
anyway if phpinfo() shows that sockets are enabled you probly don't have to
worry about that, because it wouldn't be showing up otherwise (essentially).
i'm wondering if you're trying to call socket_create() from the same place
you're running phpinfo(). are you sure the socket_create() code isn't
running from the cli perhaps?
yes to see the errors we ran it at cli. The browser page with sockets code
is just blank.
if so, a quick test to see if sockets are enabled on the cli is
php -i | grep 'Sockets Support'
Yeah, this gives no results. Hence, I think sockets are not enabled yet as
sockets.so is missing.
if nothing comes back sockets aren't enabled for the cli. if that's the
case then you will have to head into the appropriate ini file to enable the
extension for the cli. or if that's too much for you admin you can always
try
dl('sockets.so');
at the top of your script. you can also try
var_dump(extension_loaded('sockets'));
When I add this line (dl('sockets.so');) to the top of my script I get the
following error:
PHP Warning: dl(): Unable to load dynamic library './sockets.so' - ld.so.1:
php: fatal: ./sockets.so: open failed: No such file or directory in

you may need to update the locate database. this is typically done w/ the

yes to see the errors we ran it at cli. The browser page with sockets code

right, well if your report from the other day is accurate then it sounds
like you have sockets setup in the web environment and not the cli. if the
browser page is blank it could be b/c your not outputting anything from your
script to the browser.
if so, a quick test to see if sockets are enabled on the cli is
php -i | grep 'Sockets Support'
Yeah, this gives no results. Hence, I think sockets are not enabled yet as
sockets.so is missing.
run updatedb first before running locate and see if it's there or not. im
not sure how phpinfo() could possibly have reported sockets as being enabled
if you were missing sockets.so.
if nothing comes back sockets aren't enabled for the cli. if that's the
case then you will have to head into the appropriate ini file to enable the

Can I get any help on how to add or install sockets.so to the php

im not much for red hat, do they even use yum on that system or is it still
rpm? on a centos box we have a quick search turns up a sockets package,
however if you built from source, i doubt that's how you want to install
sockets support at this point.
$ yum search php | grep -i socket
php-pear-Net-Socket.noarch : Network Socket Interface
also dude, it sounds like your admin is struggling... these questions are
the sort an admin would be expected to answer pretty much anywhere ive ever
worked. like, how do i install software on the os im responsible for ..

Since you complied with --enable-sockets, you shouldn't even need sockets.so to
be dynamically loaded. But at this point, it is something that I would try
anyway.
Add:
extension=sockets.so
in your php.ini file just to see if it brings the function to light.
Your Linux installs I am sure were compiled with it in it. Especially if it is
a dist package.
The absence of the function is telling me that PHP is not compiled with
--enable-sockets. If it was compiled in properly, you would be getting
different errors. I am not saying that you didn't do it. Something may have
happened in the process.
By adding the sockets.so, you are adding the extension dynamically, incase you
were mistaken by the compile or incase there was some sort of anomaly that the
rest of PHP compiled but the sockets section was botched. Solaris is (I guess)
known to be lacking when it comes to C compilers (at least according to the
Unix geeks that I sit next to at work). But it seems to me that it would all
have failed or it would have all worked.

?
This is actually in a loop, so I can get all the data if split up.
So,
for example, here's how the data split up in 3 iterations (for 1000
bytes):
650 bytes
200 bytes
150 bytes
But if I can accept up to 2048 bytes per socket read, why would it
not
pull all 1000 bytes initially in 1 step? Any thoughts on this would
be
greatly appreciated!
Because that's the way TCP/IP works, by design. TCP is a stream
protocol. It guarantees all of the bytes written to one end of the
pipe
will come out the other end in the same order, but not necessarily in
the same groupings. There are a number of buffers along the way that
might split them up, as well as limits on packet sizes in the various
networks it passed through. So you get what is available in the last
buffer when a timer expires, no more, and no less.
If you have serialized data that needs to be grouped in specific
blocks,
your application will need to keep track of those blocks,
reassembling
or splitting the streamed data as necessary. You could use UDP which
does guarantee that packets will be kept together, but that protocol
doesn't guarantee delivery.
Thank you for your input.
Is it guaranteed that at least 1 byte will be sent each time? For
example, if I know the data length...
?php
$input = '';
for ($i=0; $i$dataLength; $i++) {
// Read 1 byte at a time
if (($data = @socket_read ($socket, 1, PHP_BINARY_READ)) !==
false) {
$input .= $data;
}
}
return $input;
?
Or is this a completely unreasonable and unnecessary way to get the
data?
While I have written a lot of code to manage sockets over the years, and
coded a UDP/IP stack, I have never done it in PHP. And unfortunately, I
don't have time to experiment right now. My boss is waiting for the next
product release from me.
Getting one byte at a time is somewhat wasteful, as it requires more
system calls than necessary. That's a lot of wasted overhead.
Whether you always get one or more bytes depends on a number of factors,
including whether the calls PHP uses are blocking or non-blocking, plus
there may be ways to switch the socket back and forth.
Have you tried doing a Google search on the group of PHP functions you
expect to use. That should come up with some sample code to look at.
Bob McConnell
I agree that one byte at a time is wasteful. I'm sure others haven't
implemented something along these lines, but I wrote a much more efficient
way to make sure I grab all the data of a known length...
?php
function readSocketForDataLength ($socket, $len)
{
$offset = 0;
$socketData = '';
while ($offset $len) {
if (($data = @socket_read ($socket, $len - $offset,
PHP_BINARY_READ)) === false) {
return false;
}
$offset += strlen ($data);
$socketData .= $data;
}
return $socketData;
}
?
If not all the data is obtained on a read, it will loop until the amount of
data is the same as the length requested. This is working quite well.
Thanks Bob and the others!

Shawn, You're looking at it inside out. Yes, the individual packets are tracked by the stack, to make sure they arrive in the correct order. But the size and fragmentation of those packets have no relationship at all to any data structure the application layer may imply. They simply implement a communications stream to reliably move octets from one point to another. If the application needs structure, it has to manage that for itself. For UDP, if you write a 32 byte packet, the matching read will get a 32 byte packet, if it arrived at the receiving stack. Missed data detection and retry requests are left up to the application.

Thank you for your input.
Is it guaranteed that at least 1 byte will be sent each time? For
example, if I know the data length...
?php
$input = '';
for ($i=0; $i$dataLength; $i++) {
// Read 1 byte at a time

false) {

While I have written a lot of code to manage sockets over the years, and
coded a UDP/IP stack, I have never done it in PHP. And unfortunately, I
don't have time to experiment right now. My boss is waiting for the next
product release from me.
Getting one byte at a time is somewhat wasteful, as it requires more
system calls than necessary. That's a lot of wasted overhead.
Whether you always get one or more bytes depends on a number of factors,
including whether the calls PHP uses are blocking or non-blocking, plus
there may be ways to switch the socket back and forth.
Have you tried doing a Google search on the group of PHP functions you
expect to use. That should come up with some sample code to look at.

I agree that one byte at a time is wasteful. I'm sure others haven't
implemented something along these lines, but I wrote a much more
efficient way to make sure I grab all the data of a known length...
?php
function readSocketForDataLength ($socket, $len)
{
$offset = 0;
$socketData = '';
while ($offset $len) {
if (($data = @socket_read ($socket, $len - $offset,
PHP_BINARY_READ)) === false) {
return false;
}
$offset += strlen ($data);
$socketData .= $data;
}
return $socketData;
}
?
If not all the data is obtained on a read, it will loop until the
amount of data is the same as the length requested. This is working
quite well.
Thanks Bob and the others!

Re: [PHP] Re: php sockets
well i mean even if we would not consider that particular piece of code as an example of the code that i have issues with im still rather interesting if theres some different between the socket model used by say, c++(winsock in my case) and the sockets used in php because when made a simple c++ script (winsock based) which just echoes what its gotten from a client i still get a problem which looks like this: when php client connects to the serv, the server then gets into an endnless loop loading the cpu almost up to max . Although i get a message from it in the php script (which server was supposed to send when the client connects) but the server itself doesnt work correctly for some reason, and thats what im curious about. Again, when i rewrote the whole functionality of the client in c++ it worked just as it was supposed to, while being written in php(client part) it all messes up.

With any code doing a basic socket functionality, the code that i gave in the original post is suppossed to connect to a deamon, and get a message from it , instead it makes the deamon go crazy in the sense that it starts endless looping and loads the system resources up to max.

[PHP] Sockets as a module or a separate PHP CLI instance?
I need to do some socket work on a production machine that is constantly busy so I don't dare re-compile php. Anybody know if it's possible to load the socket functions dynamically, maybe as if they were in a module? Alternatively, would it be possible to compile PHP without apache and with sockets for command line use only? If I do that I would like to give the resulting object a different name than PHP because I do have some cmd line pgms running on the machine. Is that difficult?

Anybody know if it's possible to load the socket functions dynamically, maybe as if they were in a module? If you can do --with-sockets=shared, for the configure, you should end up with a sockets.so file that you can then use http://php.net/dl to load into your scripts that need sockets... At least, *some* extensions this works... Alternatively, would it be possible to compile PHP without apache and with sockets for command line use only? Definitely. Just compile it as CLI or CGI, without the --with-apxs or --with-apxs2 or whatever pulls in Apache. If I do that I would like to give the resulting object a different name than PHP because I do have some cmd line pgms running on the machine. Is that difficult? Then don't do 'make install' but just copy the bin/php over to /usr/local/bin/php-with-sockets Then you can do php-with-sockets -q whatever.php to run that one special PHP binary. Alternatively, you can download the PHP source to a whole new fresh directory, compile it for CLI, and then leave it there, and use: /path/to/php/src/php/bin/php -q whatever.php so that you are running the special php binary from that source directory instead of the usual one in /usr/local/bin (or wherever yours lives) I did that for a CVS version when I needed a patched PHP on a shared host, and it worked pretty well for a cron job. It would be kind of cumbersome for something you wanted to run by hand from the shell a lot, but for a set it and forget it cron job, it was fine for me. -- Some people have a gift link here.

Re: [PHP] Sockets problem
Thanks for the answer. In the meantime I've managed to solve the problem be removing the pcntl_wait call. Actually I think this is a bug, because as I understand things pcntl_wait shouldn't block the main process, but I don't have experience with either sockets or Unix process, so I might be wrong.

[PHP] PHP Sockets - How to detect client disconnection?
How do I detect a disconnected client from a socket resource? In an infinite loop, I socket_read() every open resource that passes a socket_select(). As far as I know, the only way to detect if the client disconnected unexpectedly from their socket resource is when socket_read() returns FALSE (which, during my testing, produced the warning: An established connection was aborted by the software in your host machine.). However, socket_read() doesn't return FALSE on a disconnected client's socket resource until I first attempt to socket_write() to that resource. In brief pseudo code... socket_create(AF_INET, SOCK_STREAM, SOL_TCP) while (TRUE) foreach (resource where (false === socket_select($arrayofresources, NULL, NULL, 0, 0)) if (socket_read() === false) WON'T DETECT DISCONNECT UNTIL I FIRST socket_write() I appreciate any support you offer and thank you for your time.

[PHP] Re: php sockets was Re: [PHP] socket_write eats data - solved
Probably your problems about i can send about seven messages per second may be relationed to OS's tcp connection stream buffering... try to flush every fd after write to it. I wrote a multi-threaded (pcntl_fork()) application in phpcli using many sockets and they worked well... array iterations are fast and easy too, as they have only one level... so I believe that this is really relationed to socket flushing stuffs...you can also use select() to determine when a fd is ready for write and implement a write spool... only a ideia, but probably will spent more time with the same results... well.. flush then may resolve it.

[PHP] Sockets tutorial problem in Mac OSX
Hello,
I'm just getting my feet wet with a Dev Shed sockets tutorial
(http://www.devshed.com/Server_Side/PHP/SocketProgramming/page5.html).
I am having a little problem with one of the tutorial code samples,
which should socket_write some text back to the client--except it's not
doing that. Here's the snippet:
// write a welcome message to the client
$welcome = Roll up, roll up, to the greatest show on earth!\n? ;
socket_write($spawn, $welcome, strlen ($welcome)) or die(Could not send
connect string\n);
// keep looping and looking for client input
do
{
// read client input
$input = socket_read($spawn, 1024, 1) or die(Could not read input\n);
if (trim($input) != )
{
echo Received input: $input\n;
// if client requests session end
if (trim($input) == END)
{
// close the child socket
// break out of loop
socket_close($spawn);
break;
}
// otherwise...
else
{
// reverse client input and send back
$output = strrev($input) . \n;
socket_write($spawn, $output . ? , strlen (($output)+2)) or die(Could
not write output\n);
echo Sent output: . trim($output) . \n;
}
}
} while (true);
And the output to the Telnet client:
[Valhalla:~] rene% telnet 192.168.0.77 1234
Trying 192.168.0.77...
Connected to 192.168.0.77.
Escape character is '^]'.
Roll up, roll up, to the greatest show on earth!
? Hello, this is a test.
END
Connection closed by foreign host.
[Valhalla:~] rene%
Server output:
% /usr/local/php/bin/php -q socket3.php4
Waiting for connections...
Received connection request
Received input: Hello, this is a test.
Sent output: .tset a si siht ,olleH
Received input: END
Socket terminated
This is almost exactly the same code as that used in the very first
example, with the obvious addition of debug messages and a do-while
loop [Valhalla:~] rene%
According to the tutorial, the client should see the string reversed,
but that's not happening... In the previous tutorial example it did
reverse and output to the client, and the code looks identical, save
for the do...while loop. Here's what the tutorial says should happen:
Here's the output of a sample session:
$ telnet 192.168.1.99 1234
Trying 192.168.1.99...
Connected to medusa.
Escape character is '^]'.
Roll up, roll up, to the greatest show on earth!
? Look Ma...all backwards
sdrawkcab lla...aM kooL
? jack frost
tsorf kcaj
? END
Connection closed by foreign host.
And here are the corresponding debug messages generated on the server:
$ /usr/local/bin/php -q server.php
Waiting for connections...
Received connection request
Received input: Look Ma...all backwards
Sent output: sdrawkcab lla...aM kooL
Received input: jack frost
Sent output: tsorf kcaj
Received input: END
Socket terminated
Any ideas?

[PHP] Sockets and Header data
Ever since PHP 3, I have been using Sockets to pass GET and POST information.
Yes, now that there is the caching ability, I no longer need to do it that
way, however it has never failed me and since I deal with some high visibility
applications, I am reluctant to change.
With my experience limited to GET and POST, I do not know the format of data
that is sent via the PHP header() function. For instance, if I send
header("Content-type: text/html");
header("Content-Disposition: filename=myfile");
what is actually sent?
If I send POST data, the data string looks like
POST http://209.204.172.137:80/mysql/php/menu.php
HTTP/1.0 Accept-Language: en-us
Host: 209.204.172.137:80
Connection: close
Content-type: application/x-www-form-urlencoded
Content-length: 21
session_id=1047421540
How would the two header examples above look?
Is there a PHP application that can intercept the Socket stream?

[PHP] sockets: resource(20) of type (Unknown)
Hi - I have an problem and I'm not sure how to proceed troubleshooting. I have a socket connection that I'm making to a local stunnel daemon. The connection works and is valid until it seemingly dies and the resource type becomes unknown. at timestamp: 1044900028.6608 my object has this resource: resource(20) of type (stream) at timestamp: 1044900028.6808 it becomes: resource(20) of type (Unknown) I don't think this is a timeout issue, and I can perform all of my functionality via a telnet session without any problems as well. This code used to work great, I have made recent upgrades and changed environments. However the code consistently dies in the exact place, a place where other fsocket reads and writes are successfully been made. Any suggestions would be appreciated.

Hi,
I really need some help here because I am going to lose my mind otherwise!!
A script that was running fine Friday has decided not to work for no
apparent reason today. The problem seems to be with a socket_create that
just stops the script, so I created a simple test script as shown below to
see what happens. When I run this is simply drops out at the socket_create,
no error message, nothing. Again this worked fine Friday and nothing has
changed on my machine. I am running 4.2.3 on Win2K... any ideas? Help!!

if ($slip_socket 0) {
echo socket_create() failed: reason: . socket_strerror ($slip_socket)

} else {
$result = socket_connect ($slip_socket, $zone, $port);

This is how sockets work, if you close the process holding the socket, the conection is closed. There is no function reopen_the_old_conection.

Re: [PHP] Sockets
Yep, if you're using UNIX and compiling from source, you must add this switch to the command line when you're configuring and compiling PHP: --enable-sockets (e.g.: ./configure --enable-sockets). If you're using a prepackaged version (RPM or Windows) then you should look into the documentation for your version to see if this extension was included when the package was compiled from the source.

Although pcntl and fork() were mentioned, you might want to look at socket_select() as an alternative. Using socket_select(), you can set up a multiplexer to handle multiple sockets at the same time.

[PHP] PHP sockets/daemon problem
I'm trying to write a simple PHP script that communicates with a daemon

Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
9
25Connection closed by foreign host.
When I try doing this with PHP, however, the output is 2[]5 (where [] ==
a small square symbol).
Here is the script:
?php
$fp = fsockopen(127.0.0.1, 60324, $errno, $errstr);
if (!$fp) {
echo ERROR: $errno - $errstrbr\n;
} else {
socket_set_blocking ($fp, 1);
socket_set_timeout($fp, 200);
fwrite($fp,9\n);
$return = fread($fp,4);
echo $return;
fclose($fp);
}
?

[PHP] --enabel-pnctl / php sockets
I have recently discovered php's binary capabilities, and am using it to write a virtual isp management system, so that a php binary will listen to a port, and spit out an interface, such as webmin, etc...(http://vispman.org) This interface will be able to add virtual domains, restart dns, qmail, etc... I have seen a couple of other php binary projects(using php sockets), such as phserv, where an entire web server (like apache) has been written in nothing but php. I tried to install these, and they wouldn't run without php compiled with --enable-pcntl Now, it is my understanding that --enable-pcntl is for process control, and it only works if you are compiling php as a cgi module, and not as an apache add-on. (at least that is the error I got , when taking a redhat php rpm, and editing the spec file to include the --enable-pcntl) Is there any way to get that to compile, while maintaining all original functionality in the redhat php rpm? What I am really looking for here, is a php binary, that will spit out a web control interface(standard web page, with forms on the client side) That will listen on a non-apache port, and if a connections is detected, lock it in securely... But...still allow other connections, (like apache listens to minservers/maxserversmultiple sessions on one port) The idea being that one isp might have multiple admins/staff entering in domain information.

Check out phpserv. -Original Message- From: Barry Smoke [mailto:[EMAIL PROTECTED]] Sent: 06 May 2002 19:07 To: [EMAIL PROTECTED] Subject: [PHP] --enabel-pnctl / php sockets I have recently discovered php's binary capabilities, and am using it to write a virtual isp management system, so that a php binary will listen to a port, and spit out an interface, such as webmin, etc...(http://vispman.org) This interface will be able to add virtual domains, restart dns, qmail, etc... I have seen a couple of other php binary projects(using php sockets), such as phserv, where an entire web server (like apache) has been written in nothing but php.

RE: [PHP] --enabel-pnctl / php sockets
After further research, (reading the redhat php spec file completely) I discovered how they were making it, so that php binaries, and apache php module was working at the same time... The rpm builds the cgi root, and installs it, and the builds the apache root, and installs that over the cgi installation, which overwrites some things, but fortunately(as the spec file documents) they are compatible... So, I simply went to the spec file, where it built the cgi tree, and --enable-pcntl \ and rpm -ba phpx.spec, and viola, pcntl support in the php binary! Hope this helps others Barry Smoke Project Leader Vispman.org -Original Message- From: Barry Smoke [mailto:[EMAIL PROTECTED]] Sent: Monday, May 06, 2002 1:07 PM To: [EMAIL PROTECTED] Subject: [PHP] --enabel-pnctl / php sockets I have recently discovered php's binary capabilities, and am using it to write a virtual isp management system, so that a php binary will listen to a port, and spit out an interface, such as webmin, etc...(http://vispman.org) This interface will be able to add virtual domains, restart dns, qmail, etc...

[PHP] sockets and flush()
i have a script that makes a socket connection about halfway through the page. nothing on the page prints until the socket operation is finished, even if i call flush() prior to the socket operation. does anyone now of a way to force PHP to output the buffer prior to executing the socket code? thanks! dietrich [EMAIL PROTECTED] dietrich.ganx4.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP] sockets and flush()
Are you using ob_start () and ob_end_flush() ? If not then declaring ob_start () as the very first ? ob_start (ob_gzhandler); function call and ob_end_flush() where you want the string to output should do the trick.

Re: [PHP] sockets and flush()
Hmmm I'm no expert on web IO between Apache and PHP, but my guess is that Apache is holding the data and waiting for more. To verify this I recommend that you try running from a shell cgi and see if your string is flushed to stdio as it should. I remember running into a similar problem one time while performing a remote file(). Cheers, Rob.

[PHP] Sockets with windows / win32 - 'call to undefined function: ...'
Hi.. The error I get is this one: Fatal error: Call to undefined function: socket() i'm 100% positive that all my code is correct.. anyone else have this problem, or anyone else NOT having this problem? I have a win2000 with iis 5.0 and it's latest updates. the latest version of php too.. Best regards, -Oddis-
RE: [PHP] Sockets with windows / win32 - 'call to undefined function: ...'
Socket() function does not exist in PHP at all.
