如何在PHP 5.4中启用exec？

Question

我试图运行exec，shell_exec在php5.4中不起作用。我没有在php.ini中找到“Safe_mode”（也读过这个删除）。任何解决方案？，帮助我！

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 &"); 
    } 
}
