I currently have a script which will run via the browser and separately via the "php" command line tool.
Now the problem is, I am able to access the Apache Environment variables while script being called from the browser, but unable to access it while the script is called via command line.
How can I get the Apache environment available to the command line script as well ?
First, you must declare your environment variable using this command:
export APPLICATION_ENV=development
Then you can get it in your application cli with the function getenv('APPLICATION_ENV');.

I'm trying to execute a PHP script from the command line. In this script I'm accessing the apache2 environment variables but it won't let me. When I call the script from a browser it works. But I need it to work from the command line, because it should run asynchronously.
I access the environment variables via the getenv() function.
I've set the environment variables in the " /etc/apache2/sites-available/000-default.conf" file.
I'm running a CakePHP project under XAMPP (Apache) on Windows 10 Anniversary Update.
Apache is running under my user account.
The app calls several external processes via shell_exec(): ImageMagick, phantomjs execute as expected.
I also want to call a bash script, that in turn calls ImageMagick under Ubuntu bash (installed separately, via apt-get). I've had to adjust all paths into a form that bash can resolve.
bash /mnt/e/Projects/project-name/website/bin/crop_to_aspect.sh 1 1
/mnt/e/Projects/project-name/website/webroot/images/agent_photo/tmp_ed564289-a6f6-45b7-b9f3-2aec2b8bb3d1.jpg
/mnt/e/Projects/project-name/website/webroot/images/agent_photo/ed564289-a6f6-45b7-b9f3-2aec2b8bb3d1.jpg```
The command fails when called via shell_exec(). The same command, written to CakePHP's log, and then called from a cmd.exe prompt, works perfectly.
Thinking it may have been a path issue, I wrapped the same script in a windows batch file, including the full path to bash. I called the full batch file path, ie:
#echo off
SET aw=%1
SET ah=%2
SET in=%3
SET out=%4
C:\Windows\System32\bash.exe /mnt/e/Projects/project-path/website/bin/crop_to_aspect.sh %aw% %ah% %in% %out%
This script is then called:
E:\Projects\project-path\website\bin\crop_to_aspect.bat 4 3
/mnt/e/Projects/project-path/website/webroot/images/listing_photo/tmp_ed564289-a6f6-45b7-b9f3-2aec2b8bb3d1.jpg
/mnt/e/Projects/project-path/website/webroot/images/listing_photo/ed564289-a6f6-45b7-b9f3-2aec2b8bb3d1.jpg
Once again, the command executes correctly in cmd.exe but does nothing when run via shell_exec() from the PHP script.
Check if a function is not in the list of functions disabled in php.ini (disable_functions) line
I am trying to run a php script on a remote server using ansible.
Running the script with the ansible user (which ansible uses to login to the server) works perfectly. The ansible task however fails when there are include statements in my php script.
My php script lays in /srv/project
it tries to include includes/someLibrary.php
Everything works fine when running the script as any user with the correct access rights but when running it via an ansible task
- name: run script
shell: 'php /srv/project/script.php'
it fails with: failed to open stream: No such file or directory in /srv/project/includes/someLibrary.php
Running a very basic php script works nicely though.
I just found the solution to the problem.
The problem was that when I executed the script by hand, I connected to the server and cd'd into the /srv/project directory before calling php script.php PHPs include in this case looks in the current directory for the files I want to include. When ansible connects to the server it did not change the directory thus producing the no such file or directory error. The solution to this is simple as the shell module takes a chdir as an argument to change the directory to the one specified before running the command.
My ansible task now looks as follows:
- name: run script
shell: 'php /srv/project/script.php'
args:
chdir: '/srv/project'
Thanks everyone for your help!
Ansible runs under a non-interactive ssh session, and thus does not apply user environment settings (eg, .bashrc, .bash_profile). This is typically the cause of different behavior when running interactively vs. not. Check the difference between an interactive printenv and raw: printenv via Ansible, and you'll probably find what needs to be set (via an ansible task/play environment: block) to get things working.
I'm trying to run a ROS shell program on the server through php on Ubuntu 14.04. I have tried using system, exec, shell_exec but nothing happens and I don't get any output. The system call is the following:
echo shell_exec("/opt/ros/indigo/bin/rosrun gazebo_ros spawn_model -database Part_A -gazebo -model Part_A");
What are the limitations of using system or exec to run any shell command through php on a server?
I don't care as much about the output of the command as for its execution. I think the problem has to do with the fact that PHP doesn't have any PATH like shell does so it can't find any applications without specifying the exact location. How can I make PHP se the same PATH shell does?
The problem was that the apache user and the environment in which the bash commands are running are not set up correctly. I followed the instructions from this answer but instead of using "source" I used "." and instead of using the source.bash file I used the source.sh file. I also set all the environment variables that had to do with ros or gazebo using the putenv() function.
I have some PHP scripts for database maintenance in my server that requires its periodically execution. Obviously the easiest solution is to schedule its running with system cron.
The scripts require some server variables accessed from $_SERVER, like database hostname, cron parameters, etc.
I can run the scheduled cron commands from command line without any problem, and everything seems to be working fine (calling something like php filename.php). However, when the same commands are executed from cron, the scripts fails and the error reported is like the following:
PHP Notice: Undefined index: RDS_DATABASE in
/var/app/current/app/xx/Db/ConnectionFactory.php on line 8 PHP
Seems that the $_SERVER variable is not correctly initialized when running from cron, but it works from command line. I have tried with crontab -u ec2-user -e but without luck.
I do not want to use wget to run the script as it adds some overhead, and the scripts are hidden from being accessed from HTTP.
Any hint about successfully accessing $_SERVER from command line, but failing when running from crontab?
Had the same issue. Found a solution:
echo "InstanceID: ".get_cfg_var('INSTANCE_ID')."\n";
For some reason it was working fine on my ec2 user but not as a root cron job. Using the function instead of accessing the $_SERVER array solved my problem.
$_SERVER only works if you will run PHP using any web server. If you will use crontab and execute PHP via command line it will not work. You may refer to PHP documentation http://php.net/manual/en/reserved.variables.server.php#refsect1-reserved.variables.server-indices
As #Baminc and #Ankur says the solution is to use get_cfg_var function to get the information because $_SERVER only works when you access it from a web browser.
What I do is the following for example with SERVER_NAME :
if (isset($_SERVER['SERVER_NAME'])) {
$myServerName = $_SERVER['SERVER_NAME'];
} else {
$myServerName = get_cfg_var('SERVER_NAME');
}
Hope this helps!
