title: php related error in linux terminal while setting up symfony framework
body: <p>i am trying to setup a new symfony framework project on ubuntu by following the documentation. But all the commands mentioned in the docs starting with 'php' give out the following error.</p>
  
  <pre><code>The program 'php' is currently not installed.  You can install it by typing:
  sudo apt-get install php5-cli
  bash: php: command not found.
  </code></pre>
  
  <p>But php is installed and running on the system! How do i get past this error ?  </p>
  
  <p>Thanks in advance. </p>
