It works when execute from IDLE and Console, but when I trigger python script from PHP the PiCamera won't work.

import picamera from PiCamera
from time import sleep

camera = PiCamera()
camera.start_preview()
camera.capture('/home/pi/Pictures/image.JPEG')
camera.stop_preview()
camera.close()

<?php
    $command = escapeshellcmd('python3 /home/pi/Downloads/code.py');
    $output = shell_exec($command);
    echo $output;
?>
