RE: [PHP] cURL in an exec() . more
[snip] As a matter of fact, when viewing the source (which should display properly if word wrap is off in Notepad) the line appears to be broken up. I have an idea...write the line to a file then open the file and get the line for exec()...blabbering now, must go... [/snip] I have fixed many things and had many great suggestions pointed my way, I appreciate all of it! So to state the problem in the light of this new day here is what I have; From the command line this works perfectly; curl -d name=mynamepassword=mypasswordbtnsubmit=submit -s -o cdrlist.html https://theserver.com/download/list.html Using exec() (or shell_exec(), or others in the family) like this; exec(curl -d \name=mynamepassword=mypasswordbtnsubmit=submit\ -s -o cdrlist.html https://theserver.com/download/list.html;); does not work. I have made sure that the output of the exec() is all on one line through many tests. I have placed the command line arguements in variables and re-done the exec() call as many ways as I can think of. Is anyone aware of any problems with exec() that may be causing this behavior? Any insight would be grandly appreciated. Thanks! Jay -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] cURL in an exec() . more
OK, here is where I am (between handling other pre-holiday/long weekend processese here); I have the PHP script create a shell script containing the needed code for the cURL process. Of course the shell script will execute from the command line with me as 'root'. But the exec() that calls the shell script will not execute the script because of improper permissions. (Has to do with the permissions on the topmost directory for where the file lives, changing that could be dangerous from a security standpoint). So I have tried to change those (I am on a Linux box) via the PHP, no luck. It will let me chmod the shell script via the PHP script. So I tried to move the script to /usr/local/bin; rename(getlist.sh, /usr/local/bin/getlist.sh); Permission denied exec(mv getlist.sh /usr/local/bin/getlist.sh); Permissiion denied exec(cp getlist.sh /usr/local/bin/getlist.sh); Permissiion denied I am looking into posix_setuid() to change the permissions for the time needed, but I've a feeling, after a couple of tests, that this is not going to be the way to do this either. I wish permissions in Linux were more straigtforward. Anyone have an idea how to do this with opening the server wide? Thanks for all your help.

Re: [PHP] cURL in an exec() . more
Check out setuid and sticky bits for the file permissions. Remember that if you are running php under apache and you try the exec with a command php is running with apaches permissions. So apache needs to be able to run what ever you are trying to run with the exec command.

Re: [PHP] cURL in an exec() . more
Ah! I know what you're feeling about Linux. I had that problem using PHP and text editing software (for programming) with Caldera, like ftp timeout, security, file path, etc. It become too much for me, so I junked it and went back to AIX. I haven't tried it on Red Hat but I can easily turned off hte ftp timeout, etc. from there. Haven't tried PHP stuffs on Red Hat.

I'm not sure I understand you. You have a php script which creates a
shell-script. Then you have a php script which exec('shell-script')? Assuming
that the php script is run by the same user throughout then I don't see why
it cannot exec your shell-script. Perhaps you can elaborate.

It will let me chmod the shell script via the PHP script.
OK ...
So I tried to
move the script to /usr/local/bin;
so why do you need to move it? Why can't you exec() it where it is?
Try hand writing a script then exec() it from php.

It's always the smallest things that will get you, I should be slapped (preferably by a good looking woman) :) exec was not broken the permissions don't have to be mucked with ownership and group can be left alone this should be stamped on the forehead of each and every PHP developer USE FULL PATHS! $bash = #!/bin/sh; $curl = /usr/local/bin/curl -d \name=mynamepassword=mypasswordbtnsubmit=submit\ -s -o cdrlist.html https://theserver.com/download/list.html;; $sh = fopen(/var/www/htdocs/rcr/getlist.sh, w+); fputs($sh, $bash.\n\n); fputs($sh, $curl); fclose($sh); chmod(/var/www/htdocs/rcr/getlist.sh, 0755); exec(/var/www/htdocs/rcr/getlist.sh); This solved all of the problems. I did the full paths thing during the process of elimination, to remove all doubt about the code. This will make sure that the script can be found and executed. On another note; Had I done this with exec and the cURL statement earlier it would have worked as well. But I think that i am going to keep it this way as it will hopefully make the code clearer. I will have to write more cURL statements later in the script and I can then assemble shell scripts as needed. Thanks for all of your help...
