title: Is it a bad practice to use spaces in PHP associative array indexes?
body: <p>I have to pass some parameters using an associative array, something like this:</p>
  
  <pre><code>$blockGroup['name=products type=complete']
  </code></pre>
  
  <p>Doing some tests i saw that it works, but is it a bad practice? Is it possible to generate any bug or unexpected behavior?</p>
  
  <p>Thanks for any suggestion!</p>
  
  <p><strong>EDIT 1</strong></p>
  
  <p>I am using this array in a view implementation, the complete structure is:</p>
  
  <pre><code>$blockGroup['name=products type=complete'][] =
      array(
          'name'  =&gt; 'GeForce',
          'value' =&gt; '99.99'
      );
  </code></pre>
