PHP no permission to write to file in MAC

Question

I am using XAMPP(PHP APACHE MYSQL) to develop a program in MAC. When I try to use JPGRAPH to write to file, code: $fileName = "/img/bar.png"; $graph->img->Stream($fileName); $fileName = "/img/bar.png"; $graph->img->Stream($fileName); I got this warning: Cant write to file, check that the process running PHP has enough permission. I searched a lot, and tried many ways: 1.sudo chmod 777 ~/File/Java/img 2.change user name in Apache httpd.conf (default username is nobody) 3.mkdir($create_path, 0777). Still I cant figure it out. Any suggestion?

Answer 1

尝试删除/img/bar.png开头的/

Answer 2

Try

   $root = $_SERVER["DOCUMENT_ROOT"] . "/img";
   $fileName = "$root/bar.png";
 

Hope this helps.
