使用STDIN和STDOUT使用shell_exec或exec其他任何东西从命令行运行python文件wih输入传递

Question

I want to run a python file from my php code using exec function. To do so I use command "python test.py" and if I print "Hello World", it is showing.

For this my php code is like this:

<?php
$Data = exec("python test.py");
echo $Data;
?>

And the python code is:

print("Hello World")

Now I want to pass an input value say my name "Razin" to the file. So that it will print "Hello Razin".

Here is my python code

x = input()
print ("Hello "+x)

which should print Hello Razin. And from php I catch it.

I don't want to pass arguments and use python system to catch that. I want to make it like code judge system.

I hear about pipe and I read it. But it didn't clear my concept.

N.B: If you can also describe if there is more than 1 input then it'll be a great help.

Finally I found the solution. The best way to do so is using proc_open()

The code sample is given below.

$descriptorspec = array(
                    0 => array("pipe", "r"), //input pipe
                    1 => array("pipe", "w"), //output pipe
                    2 => array("pipe", "w"), //error pipe
                );
 //calling script with max execution time 15 second
$process = proc_open("timeout 15 python3 $FileName", $descriptorspec, $pipes);
if (is_resource($process)) {
   fwrite($pipes[0], "2"); //sending 2 as input value, for multiple inputs use "2
3" for input 2 & 3 respectively
   fclose($pipes[0]);
   $stderr_ouput = [];
   if (!feof($pipes[2])) {
   // We're acting like passthru would and displaying errors as they come in.
         $error_line = fgets($pipes[2]);
         $stderr_ouput[] = $error_line;
    }

    if (!feof($pipes[1])) {
             $print = fgets($pipes[1]); //getting output of the script
    }
}

proc_close($process);
