I have written a PHP Script, I run the code like this on MS-DOS on my local PC:
C:\wamp\bin\php\php5.3.0\php.exe index.php
Now I want to upload the index.php on the web but on multiple computers (without PHP/Apache installed), how can I run index.php on ms-dos via web?
If that not possible, I can open multiple putty application on each computer and login ssh?
index.php will continues looping - it wont be good to run script on the browser because it may cause timeout via browser.
You can't. If you're using putty on each computer to log into another machine to run the script, the script will still be running on "the other" machine. All you've done is make its output appear on the local computer that's running putty. It'd be exactly the same as opening multiple shells on the server and running the script in each window.
If you want a PHP script to run "locally", then you need PHP installed locally on each machine that will run the script. And like I said in your other similar question, there are PHP compilers which can produce a .exe that MIGHT be portable, but it's not guaranteed to work. PHP can be compiled, but not all scripts are compileable.
Check out bamcompile.
It lets you compile the PHP file to an exe.
Not everything works but it is worth the shot: http://www.bambalam.se/bamcompile/
I think it uses PHP 4.something so don't know wether it works for your script without seeing it
EDIT
You said you are worried about an timeout if ran in browser.
What does the script do?
Perhaps PHP isn't you're best option.
The easiest way would be to have Apache and PHP installed on those computers, and then have a script visible on that computers that runs the command for you.
exec("C:\wamp\bin\php\php5.3.0\php.exe index.php")
This way, you can start running the script without having the script time out from Apache's end.

I'm just starting to code with PHP, learning the basics. So far it's just pretty standard stuff. I'm coding & testing it locally using xampp.
When I've finished the file I'm able to FTP the .php file to a server, and run it on the server using a browser on my local PC. (eg. www.mydomain.com/myphpfile.php)
So far so good. But what if I want the PHP script to run on the server permanently? So it will sit there doing stuff without me needing to run it from a browser?
How do I execute it, and how do I know if it's running (given that because I'm not running it via a browser I can't see any echo text for example)?
I can't find anything obvious as everything seems to revolve around running it from a browser, or running it locally.
I'm new to web development. I'm trying to execute a shell script using PHP's shell_exec(). Inside the script, I'm trying to invoke a GUI application(Qt). When I executed the PHP script from a terminal the application started as expected. But when I opened it from browser an empty blank page appeared.
I'm using Ubuntu with apache2 server running as service. When I searched in google, the similar problem is solved in the Windows environment by allowing apache service to interact with the desktop.
PHP Script:
<?php
$log = shell_exec('sh testcmd.sh');
?>
testcmd.sh:
./Program1
Any help provided will be highly appreciated.
It is somewhat unclear what you're asking.
If you wish that browsing to a certain web site will run a PHP script that will open a GUI app for the client to interact with, the answer is "you can't". The reason is that the way the setup works is that the server and the client run on different machines, and your PHP runs on the server machine. As such, the client never gets to see the running program.
The above is true also for Windows. The answer you quote in your question does not apply to a server running on a different machine than the client.
If, for whatever reason, you want something that works only when the server and client run on the same machine (or there is someone watching the server's display), then you need to do the equivalent of the Windows answer.
The graphics display on Linux (assuming you're not running wayland) is using a protocol called X11. In order for the display to appear, your GUI program needs two things. The first is to know which display it needs to use. This is supplied with an environment variable called DISPLAY. The second is an authorization to actually use that display.
So in order for your PHP script to run a GUI app that will show its GUI, you will need to first do the following steps:
Set the DISPLAY variable to the correct value (copy from your desktop environment).
Run xauth add something, where you can get what something is by running xauth list on your desktop environment.
If you do these two things (in this order), your GUI should show up.
I have two html forms and two php scripts. The first one is a form which is supposed to submit a users email to a .txt file, and the other is a Stripe payment form which uses php code to charge the customer.
Now my problem is that there are some issues with the two php scripts, that I can't figure out how to fix, because I am not really sure how to test the scripts. Normally when testing the html scripts I would just open the html files in my browser, but that doesn't work on my php scripts as the site just shows what is written in the scripts when called/submitted.
So my question is how do I test my scripts, without having to use a hosting account and can I even test it like this?
You need to run a web server on your local computer to test it out. I would suggest looking into something called Vagrant, which allows you to fairly easily create virtual machines on your computer in which you can install anything you like without fear of messing up anything else. If you go here you can even find a "box" to create a virtual machine that already has apache and php installed.
Depending on your version of PHP there's a webserver builtin right into PHP:
http://php.net/manual/en/features.commandline.webserver.php
You probably have to install a web server locally with php enabled. Since php is a server side language it needs a server to run on, in order to send you back the html, after execution. If you need to see the result on a browser.
http://en.wikipedia.org/wiki/LAMP_%28software_bundle%29.
Or run your script from terminal (you must have php installed) if you don't need to see the result in the browser and just want to run your script.
$ php myscript.php
I have a little Apple script as follow:
beep
delay 2
tell application "Finder" to activate
It just makes a sound, wait 2 second and then bring the "Finder" window to the foreground.
When I run it from the command line, it works fine.
Then I want PHP to call that script using the exec() php function.
<?
$cmd = "/usr/bin/osascript \"myscript.scpt\"";
exec($cmd);
?>
It still works fine.
But when I call that same PHP script from the browser, it doesn't work! The PHP starts, the Apple script starts as well since I can hear the beep sound but its last line is not executed.
I thought that would be an environment variable thing so I made sure they were all the same way as in the terminal:
$cmd = "HOME='/Users/mikael' && … && /usr/bin/osascript \"myscript.scpt\"";
The variables are set properly (as check with env|sort) but still no luck with running my apple script inside a php script displayed in the browser and using the standard MacOS apache stuff.
Any idea?
When osascript runs from PHP, through the web server, it's not running with a login context, so it can't send Apple events to applications running on the desktop (like the Finder). You'll find that a similar issue arises if you try to use osascript over SSH.
Login contexts are a complex, poorly documented area of OS X. You may want to get your hands on a copy of Amit Singh's Mac OS X Internals: A Systems Approach if you want to learn more about them.
If you don't, though, the answer is generally pretty simple: don't depend on osascript working correctly from the web server.
OK, I may have found a way that allows the Apple script to be called from PHP from within a browser.
It is not fully satisfactory but this is what I'm going to do:
So basically instead of using the default macOS apache server, I use this one that sets up a web server & also MySQL: http://www.mamp.info/en/index.html
I mention MAMP but there may be other.
my Apple script is finally run fully using that solution.
I had the same trouble and realised that apache executes as user www.
You can change this by editing etc/apache2/httpd.conf . Change user to your user short name and group to staff.
I have some PHP scripts that reside on a network share. For argument's sake, let's call the share \\nas\dev. I have a Web Site on \\w2k3dev\ set up in IIS6 that uses \\nas\dev\ as its home directory by setting "A share located on another computer".
Some of my scripts use shell_exec to execute functions on the server and return results to my script. Again for argument's sake let's say I'm just getting a directory listing like so:
echo shell_exec('dir');
If I run the script in IIS, I get no output - but no error logs either.
If I set up Apache on \\w2k3dev\ and configure it to use the same share, the script runs fine
If I copy the script to the local machine and run it through IIS it works fine.
So the problem only seems to be when IIS is set up to use a network share with a script containing shell_exec. Every other aspect of my scripts work fine.
Profiling in procmon, I can see that cmd.exe operates completely differently depending on whether it's being run by IIS or Apache. I have more details, but for the sake of being concise, I will omit them for now unless someone asks for more details.
Thank you so much for looking at this, I am at my wits end.
Kind regards
Iain
You may have a look at those IIS specific comments on php.net shell_exec's manual :
