php exec('ps -aeo') doesn't return all processes

I'm trying to build a simple php script to return a JSON formatted list of running processes.

This script of course is executed by apache.

I have everything figured out except one little detail. When the script is executed by apache the command only returns a list of running processes that are owned by the 'apache' user.

Is there anyway around this?

exec('ps -aeo',$output);
//then some code to parse the $output and return a JSON string

OUTPUT:

"processes": [
    {
      "cpu": "0.0",
      "pid": "23698",
      "user": "apache",
      "command": "/usr/sbin/httpd"
    },
    {
      "cpu": "0.0",
      "pid": "23486",
      "user": "apache",
      "command": "/usr/sbin/httpd"
    },
    {
      "cpu": "0.0",
      "pid": "23485",
      "user": "apache",
      "command": "/usr/sbin/httpd"
    },
    {
      "cpu": "0.0",
      "pid": "23484",
      "user": "apache",
      "command": "/usr/sbin/httpd"
    },
    {
      "cpu": "0.0",
      "pid": "23483",
      "user": "apache",
      "command": "/usr/sbin/httpd"
    },
    {
      "cpu": "0.0",
      "pid": "23482",
      "user": "apache",
      "command": "/usr/sbin/httpd"
    },
    {
      "cpu": "0.0",
      "pid": "23481",
      "user": "apache",
      "command": "/usr/sbin/httpd"
    },
    {
      "cpu": "0.0",
      "pid": "23480",
      "user": "apache",
      "command": "/usr/sbin/httpd"
    },
    {
      "cpu": "0.0",
      "pid": "23479",
      "user": "apache",
      "command": "/usr/sbin/httpd"
    },
    {
      "cpu": "0.0",
      "pid": "23478",
      "user": "apache",
      "command": "/usr/sbin/httpd"
    },
    {
      "cpu": "0.0",
      "pid": "1008",
      "user": "root",
      "command": "/usr/sbin/httpd"
    },
    {
      "cpu": "0.0",
      "pid": "959",
      "user": "root",
      "command": "/usr/sbin/abrtd"
    }
  ]

i had the same problem, this solved it. (assuming you have root privileges)

# chcon -t unconfined_exec_t /sbin/httpd

see detailed document here

probably not a good idea if the server is shared by untrustful users
