title: How to pass an array to php from python script?
body: <p>I am running a python script from my php:</p>
  
  <pre><code>&lt;?php 
  
  $command = escapeshellcmd('&lt;path&gt;/myscript.py');
  $output = shell_exec($command);
  echo $output;
  ?&gt;
  </code></pre>
  
  <p>Now I am in the need to pass a bidimensional array of strings from the python script to the php page, but I am quite stuck. Of course, <code>$output</code> will contain a single string of the whole array. I also thought about json, but in that case I should convert the python array into a json string (this could be another question)....</p>
