[PHP] shell_exec fails to compile java class?
Hello! I need to use shell_exec (or any other similar function) in order to compile a java class-file. I have all the needed components installed on my computer (Windows XP with Java SDK) - I can use "java c:\path" in order to compile using Start->Run. When I try to do the same with shell_exec or `` it returns null and it doesn't compiles. Even when there are errors - it doesn't show them at all. I've tried to use instead of "java c:\path..." the full java command line compiler path but it didn't work either. When I try functions such as "echo test" it works. Clearly I'm missing here something - problem is... what? -- Use ROT26 for best security

I think the only way to do that would be to have a (don't know the
Windows terminology) daemon sitting on the system just continually
checking against the db/file and then it can make a call to the PHP. If
your site has a high volume of traffic, and extra DB call every now and
again won't hurt it too much. I use this for sites sometimes where I
just need something done once a day.

Re: [PHP] shell_exec - asynchronous would be cool!
Yes, believe it or not, when i was writing this, i thought about a db soln
as well. Just hadnt done it that way back then.
I guess with Linux one could do something like:
shell_exec('{longexecutingprogram -with -params; mysql -uuser -ppass
database query; } &');
Surely it should be possible in windows as well somehow. Does anyone know
how (easily)? I mean i could write a win32 executable that could do it but
that might be overkill.
But still you have to continuously check the database if the value is the
expected which seems kind of unelegant.
Or, you could call a php script at the end like so:
shell_exec('{longexecutingprogram -with -params; php myscript.php with
params; } &');
In myscript.php you could have something like:
Would this work? Maybe one could write a library for that directly in php...
So you could actually have a exec_async function without having to write a
php module or something like that. I would be interested in writing a php
module at some point anyway though. I know c(++), so it should be doable.
Is it possible to retrieve the session variables of a user in php cli?

[PHP] shell_exec - asynchronous would be cool!
Hi all, A while ago, i had a problem with shell_exec: I was writing some code to execute imagemagick to convert a bunch of images. This could take ages to execute and the page therefore ages to load. The solution was to get a linux box and append a & at the end to do it in the background or make a ajax call to a page that does it in batches. The problem was really that i had to write a file that is then checked against to know when it was finished... Not very pretty. Anyway, would it be possible to make a "new" shell_exec_async function in php that just starts the process, puts it to the background and calls a callback function or another script with parameters when it finishes? I guess a callback function is not really going to work because the page needs to finish execution. It should be possible with PHP forking though. Anyway, just an idea.

Re: [PHP] shell_exec seems to hang other web requests while running convert
We can live with the fact that it will take a little longer to process the images. The image processing is only done by 2 people, about once a month, just to save them time (they would do it with photoshop otherwise and it is really boring and time consuming). In fact, i might set up an automatic email when its finished. :-) In the future it might become an issue when people can edit their own ebooks. This project dates back to 1999, so a lot of it is legacy (a binary page definition data format...). We're thinking of moving to swf pages instead of images, as they currently are, that will reduce the time to be taken to convert a pdf by thousands and would increase the quality and reduce download times for end users, but it will take time to develop which is not at hand atm. We have been thinking about scaling issues as well for quite some time now... It was hard enough to get them to move to Linux, since i work in a .NET shop... Setting up load balancing is not a trivial task though and expensive to host. I'm the main software developer on this project and am too busy adding features and debugging ActionScript, C++ and PHP code to do that as well. Thanks for your thoughts though.

Re: [PHP] shell_exec seems to hang other web requests while running convert
cron is a good idea, havent thought about that. One could use the nice program then to give it the lowest priority, because other requests are more important than this and another server gives the issue of transfering files back and forth. Another soln would be to run it with & in the background (with nice) and then check if the file(s) exist on ajax calls to give feedback, this might actually be easier to implement. Anyway, we will fix the issue later now. Thanks.

[PHP] shell_exec seems to hang other web requests while running convert
Hi All, The following problem: Our client is converting pdfs to images with a web interface. At the moment I'm using convert from imagemagick with shell_exec (i know i could use the imagick module, but this would require quite a bit of recoding and time at the moment, it was originally running on a windows machine and i couldnt get the imagick module working on that). Is there a quick way to give other web requests to the web server a higher priority than this process? It can take quite a while to convert 100 pdf pages to images in high res with convert. At the moment only 3 images at a time are converted with some crazy ajax logic. But still while these 3 images are converted (can take 20-30 seconds) other requests seem to hang until convert is finished. I know, i can put a & at the end of the command line but then they wouldnt know when the process is actually finished. The server is an ubuntu server with the latest release. It's got Apache: Apache/2.2.8 (Ubuntu) mod_mono/2.0 PHP/5.2.4-2ubuntu5.3 with Suhosin-Patch mod_ssl/2.2.8 OpenSSL/0.9.8g Server at 208.79.206.58 Port 80 Please help.

Thanks, guys, for the responses. I'll check the events and IIS logs tomorrow. This afternoon, I put the IIS user into the Administrators group, but no luck - the same exact thing, or lack of thing, happened. I told this to the IT head and he agrees that it's probably not a permissions issue. After that he kind of warmed up to installing Apache on that box.

No real insight, but a couple philosophical questions that may lead somebody who actually does Windows into something... When one runs a .bat file, isn't one already *IN* some kind of cmd.exe shell of some type to start with? OTOH, what is PHP doing with exec() on Windows if not firing up some kind of cmd.exe shell?

RE: [PHP] shell_exec, batch files, and IIS on Windows
hi, maybe you can try this: in the IIS properties, you can define the user running your IIS service. Ususally this is IUSR_xxx, but you can set a administrator user (see directory Security/ anonymous user) try to put your win login (prefixed with your domain\ and give your password. If you can execute your cmd and batch file, then you can be sure that the problem if an authorisation problem. Afterward, re-enter the IUSR_xx user as the anonymous user, because running as administrator is rather dangerous!! Also, try the 'Integrated windows Authentication', if this is checked, the anaonymous will NOY be used, but your own login will be used instead. As an example, if the Use integrated authentication is active, try a phpinfo() and you should find your own windows login as AUTH_USER (or others, don't remember). (if you have a login prompt, you can avoid it from the IE setting) Also, have a look at the event viewer and at the IIS log file. Maybe you will see the error reported by IIS...

Well, there are several options here.
One option is to just build a password-protected web page on the other
server that does the exec() (or readfile for cpuinfo). Then you can
have PHP on server A do file_get_contents on the URL, if
allow_url_fopen is "ON"
Depending on how complex the target command is, you could also look
into running WebServices such as SOAP, RPC, REST, etc.
A valuable source of this kind of thing is from the zillion "control
panels" for webhosting that are "out there"
I think you might maybe be able to tunnel a command through SSH as a
one-off, but perhaps I'm just dreaming I read about that in man ssh a
few months ago.
To a large degree, HOW you do this depends much more on what commands
you want to allow, and even more importantly, disallow, than on
anything involving PHP. In fact, PHP itself is only a
thinly-disguised wrapper for whatever you will come up with. So
you're better off asking about this kind of thing on an OS or Linux
distribution mailing list, probably. The PHP bit will end up just
being no matter how you look at it.

[PHP] shell_exec, batch files, and IIS on Windows
The manual entry for shell_exec has a comment that notes to execute .bat files with shell_exec, you need to pass the command through cmd.exe with the /c argument. I was wondering if anyone could share some insight on why that is. I've pretty much verified that this is the case. I can't execute .bat files at all from a Windows 2003 server running IIS. I can locally on my development workstation (XP running Apache). I've tried passing the command through cmd.exe on the server, but some of the commands in the .bat file does not run properly when going through cmd.exe. I suspect that IIS is a key culprit, but I have nothing concrete. I'd like to take a plausible theory to the IT guys before I request that they install Apache on that box. Thanks for any insight anyone might have. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If you need to inspect e.g. free space on remote servers it may be more
sensible to use SNMP or some such similar protocol/system that is
designed for exactly this purpose rather than try to hack up a system in
PHP (tho' I do love my hacking!)
Have a look at Nagios. I'd imagine your servers will have some degree of
health monitoring/reporting installed anyway for your own peace of mind,
so it shouldn't be too hard to hook into that system.

Hi
I have been using the shell_exec command to perform several server queries
quite succesfully i.e. analysing files systems by gettin ginformation
returned by df -kP (shell_exec('df -kP')). do any of you guts know if it is
possible to target a command like this on another server?
So from server A where I am running a web app, needs to run the
shell_exec('df -kP') on server B, which also has php installed, so that i
can display the results in my web app on server A. Hope that makes sense!
Also, how would i fopen a file such as /proc/cpuinfo on Server B from Server
A.
Any help greatly appreciated

Re: [PHP] PHP shell_exec
Hi Ade,
Sure you can. You must develop 2 scripts. One that will act as
"server" and one as "client".
So if you want to get details of server B from server A you should
have the "server" into B and "client" into A.
Be sure the communication between these 2 servers is securised
(using a certificate or build you own encryption for communication,
restrict script response depending on server ips etc...) as you want to
pass sensitive data between them.
Communication can be done using curl library or simply with fopen
(if allow_url_fopen allows it). parameters can be passed using XML or
simple parsed plain text.

Are you working on dos/windows ?
yes)
win32 does (IMHO) not support external interpreter executables
you then must call `perl /C:/Inetpub/com/html/bf1942live/vietnam.pl`
(probaly fix the perl interpreter location if its not in $PATH)
you probably consider changing the server platform.
no)
your command path is wrong. driver letters only exist on dos/windows.

What is the answer to (ii)?
Are you able to execute any shell programs/commands at all? Hint try something
simple like shell_exec('touch /tmp/testfile') and see whether /tmp/testfile
is being created.

Re: [PHP] shell_exec with pipes
ok, i am running the script like this now:
START -
$var=shell_exec("/home/lansinplayer/server/apache/htdocs/lansinplayer/getfilelength.sh
/tmp/pitstop.mpeg");
echo "--$var--";
STOP -
Where echo returns nothing. I did a chmod 777 on the getfilelength.sh file.
When i run the file in shell i get this:
$ /home/lansinplayer/server/apache/htdocs/lansinplayer/getfilelength.sh

The Shell file looks like that:

2) Checked that (i) you're not running in safe_mode, or (ii) if you are, that
you are allowed to access those executables?
3) Confirmed that the left side of the pipe is working and giving the expected
output?
4) Tried giving the full path to grep?
If you're still having trouble with it you can try sticking the above into a
little shell script and shell_exec() the shell script instead.

Try just escaping the quotes, pipes should be OK IIRC.

[PHP] shell_exec with pipes
Hello List!
I have tried to get this command working with php for about 2Weeks now, and
i would like you to try to get this thing working.
This shell command:
/usr/local/bin/mplayer -identify -frames 0 /tmp/pitstop.mpeg 2>/dev/null|
grep ID_LENGTH | cut -d "=" -f 2
gives me the result "16" back, the LENGHT of the filename.
$var=shell_exec("/usr/local/bin/mplayer -identify -frames 0
/tmp/pitstop.mpeg 2>/dev/null| grep ID_LENGTH | cut -d "=" -f 2");
just wont for some reason! $var ist just empty.
I was playing around with stderr and stdout and stuff, but i dont know why
php wont deal with it as shell does.
$var=shell_exec("ls -al");
for examle works just fine!
Could someone please give it a try, cause i have spent hours in irc channels
and googeling around to get this solved :/
Thanks a LOT!!
Mario

RE: [PHP] shell_exec question - Solved
To all who contributed to this thread, many thanks... I tried all the suggestions offered but still had the same problem. Today I copied php.ini-dist over to /etc, restarted Apache and everything works. This process was repeated many times during the last day or so, so I don`t know what happened to make it work this time. Anyhowze, my shell_exec`s are working now, so I`m a happy camper...

No, these will be PHP's built-in default values (which are the same as the ones in one of the php.ini-* included in the PHP distribution -- php.ini-dist, I think, but I could be wrong). The trick is to look at the phpinfo() output for Configuration file (php.ini) path -- if it only gives a directory's path (ending in /, without a php.ini filename on the end), than that is the path it is looking in, but there is no php.ini file there so the built-in defaults are being used. If it gives a full pathname ending with an actual filename, that is the file it is reading. Cheers!

Mail and news messages have many headers, some of which serve to connect
messages together. You can even change the Subject: as the discussion
evolves or forks and the messages will all still be properly related to
the right parents and children. This is a good thing, even though
Microsoft Outlook really doesn't support it too well at all and many
users of it have no threading or sorting capabilities.
When starting a new topic, or "thread", please start a fresh message.
Not only is there no chance of forgetting to change the subject but the
message also does not appear glued onto another message where it really
doesn't belong.

Are you running under safe mode, which turns off shell execs? Can you
call anything via shell_exec? Have you tried using system() instead?

OK; that's a good start. We need more details, though. Tell us what
you've done and what does or doesn't happen, including any error messages
on the web page or in the apache log.

I have a little app which allows someone to enter a number and upload a PDF
file which gets faxed using sendfax. Works fine here. I'm basically doing the
same as you are:
shell_exec("sendfax $OPTIONS -d $DESTINATION $FILE");

What httpd file? You mean the log? What exactly do you see? Copy-paste the
line(s).

[PHP] shell_exec problem
Hi everybody
I have some few problems with the shell_exec command.
I want to send a fax with hylafax using the sendfax program in linux.
When I try to do shell_exec ("sendfax -n -d faxnumber faxfile") it will
not work I can see in my httpd file that linux only gets the command
'sendfax' and not the parameters '-n -d .'.
Can anybody help me?
Thanks in advance

I'm having problems running cp from shel_exec(). Nothing is returned, but the copy is unsuccessful. The same call works as user nobody from the actual shell. Any ideas? -Alec -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] shell_exec "root" question
Hi,
i wrote a script, which runs
echo shell_exec("exim -bp");
so it simply gives me the current mail queue.
However, it only works when called by user "root", because exim won't
let "group" or "others" execute it.
So, i cannot use it with apache, because it runs as "nobody".
Well, i saw scripts that can do so, but i have no clue how it is
possible for them.
Does anyone have an idea?
I thought about adding a cron-job and let it update a file every 5
minutes with the current mail queue, but that will cause unnecesary load
and it won't be up2date.
So, any ideas are welcome,
Thanks,
Duncan

Re: [PHP] shell_exec() or passthru()
And by redirect I mean to /dev/null possibly if you don't want to capture output.

Re: [PHP] shell_exec() or passthru()
You may need to redirect output (both stderr and stdout) atleast that helped me with a similar problem. My system is Linux.

[PHP] shell_exec()
Hello all, Does anyone know if shell_exec waits to have whatever it was passed to be executed before returning to the script? I am asking that because I need to write a script to compact files to a zip and then have it e-mailed to a predefined address. The files it will compact might have a considerable size and since this script will be triggered by a web page I wonder if shell_exec would be executed as a separate thread or if it will be the same one. For me, the ideal thing was to have it wait for the command to be over. Any suggestions?
