title: Wget on Centos 7.2
body: <p>I have a wget inside a php script. (wget connects to the another server to retrieve a data).
  from command line php works fine, but when I try to access it in the browser from another computer, php fails because of wget.
  All this was working on Centos 5.2 but on Centos 7.2 no way. any idea?
  chmod is set 755.</p>
