This is a python script #! Usrbinpythonm 3.12345612345 print (m); the browser can output the result when the PHP script is called like this, but when the Python script is :#! Usrbinpythonimport epicsm epics. caget (& #39; VME: Voltage_N12V & #39;) print (m). then, no output is returned when you call the browser using PHP... However, the output result phppython is executed on the terminal.
This is a python script.
#! /Usr/bin/python
M = 3.12345612345
Print (m );
This is a PHP script.
$ Output = shell_exec ('Python helloworld. py ');
Echo"
$ Output
";
?>
In this way, the browser can output the results.
However, when the Python script is:
#! /Usr/bin/python
Import epics
M = epics. caget ('vme: Voltage_N12V ')
Print (m)
In this case, no result is output when you use PHP to call the browser... However, the execution on the terminal has output results.
