title: how to initialize a PHP bidimensional array
body: <p>Let's say I would like to manage a multidimensional array like (pseudo-code):</p>
  
  <pre><code>Array $colors
  * wine,red
  * cheese,yellow
  * apple, green
  * pear,brown
  </code></pre>
  
  <p>What code could be used to avoid the following notation, to initialize the array (assuming there will be a hard-coded list of elements=?:</p>
  
  <pre><code>$colors[x][y] = 'something';
  </code></pre>
