javascript - Change background color on refresh with Vanilla JS -

-

There is a problem changing the background color when I refresh each one. Any help is appreciated that this is my JS yet: 

  var color = ['# 760c8', '# 4782b1', '# e889c']; Var change background = function () {document.body.style.background = colors ([Math.floor (Math.random (* * colors.length)]);}; Change background ();    
 
 
 You are almost there. In the line  
  document.body.style.background = colors ([Math.floor (Math.random (* * colors.length)];   
 You  [Math.flur (Math.Rendum (*) * Colors Length ).]  Otherwise you think that you want to call  colors  as a code. The index wants to use an array of what the square brackets do, so it should  
  document.body.style.background = colors [Math.floor (Math.random (* * colors.length) ];   
 and it will be alright.

php - proc_open Too many open files in long running Symfony Console app -

-
I have created a console app with a SIM console console component. It was going to run for 5 hours but after running 2 hours I have a proc_open (): Many open files in the pipeline error Symfony \ Component \ Console \ Application.php On-line 985. I tried to gc_collect_cycles in my code, but got the same error. Is this a Symphonic Console component bug or should I not run any app for this long time (but I have to)? This problem relates to: Obviously you have many resources in your app It's not a symphony console bug, but it's a PHP bug. You can modify your program by using another programming language to open fewer files.
