交互式外壳脚本命令行php

Question

I am trying to implement a feature on my web application to provide the user the ability to interact with the command line on the server.

The problem is: is it possible to integrate the command line with the web application so any result will be produced can be shown to the user even if the processes is still working in the background and any input can be taken and processed so it will be like -a function.

I have tried all the exec() shell_exec() i have tried to redirect the result of the interactive command by 2> SomeFile.txt but the output will not be the result of the interactive command

Answer 1

1.With commands return the output. Use:

shell_exec — Execute command via shell and return the complete output as a string

passthru — Execute an external program and display raw output

system — Execute an external program and display the output

2.With commands not return the output. Use:

system or passthru then check return_var argument and print the output

system('touch readme.txt', $retval);
if(!$retval){
    print 'Touched file with success';
}

Or

if(!touch('readme.txt', time())){
    print 'Whoops, something went wrong...';
}
