shell_exec blocking the thread not proceeding to next statements in windows

Question

am executing a shell command like below.

shell_exec('java -jar sanityTest.jar');
$success = array('status' => "Success",'type' => "execute");
echo json_encode($success);

The shell_exec command not going to next statement until the execution complete. What I want is to execute it in background, even for Windows.

I tried

shell_exec('java -jar sanityTest.jar >/dev/null 2>/dev/null &');

which is coming to next line but not executing the command.

function execInBackground($cmd) { if (substr(php_uname(), 0, 7) == "Windows"){ pclose(popen("start /B ". $cmd, "r")); } else { exec($cmd . " > /dev/null &"); } } — user2786092, Aug 03 '16 at 06:56

My solution: use start /B *my command*

function execInBackground($cmd) { 
  if (substr(php_uname(), 0, 7) == "Windows"){ 
    pclose(popen("start /B ". $cmd, "r")); 
  } else { 
    exec($cmd . " > /dev/null &"); 
  } 
}

I could have found it by looking at the right keywords: https://stackoverflow.com/a/21031259/6019417
