Prove all, and finally the solution for me is(uniformPortalServer): 

pclose（popen（“start / B”。$ cmd，“r”））;

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