ansiible: skip when not type function

[z_z]

- name: Httpd running ?
  shell: ps axo args |  grep httpd | grep -v grep 
  register: apache
  failed_when: false
  ignore_errors: yes <**---- if this removed I get red error on non httpd servers**

- name: Copy script
  get_url:
    url: "http://anotherscript.sh
    dest: /tmp/anotherscript.sh
    mode: 0755
    owner: root
    group: root
    force: yes
  when: apache.rc == 0

What I want is some thing along those lines
