title: multidimensional csv
body: <p>I'm trying to read a CSV file with php. I've always had situations where I know that the data is in a certain structure. However, I have a CSV where each row may have a different number of items in a row.</p>
  
  <p>Here's a small example:</p>
  
  <pre><code>121, 32, 28, 23, 43   
  322, 43, 43, 44  
  435, 23, 43  
  343, 56, 56, 678  
  </code></pre>
  
  <p>I wanted to output something where I want to out it as such: <br>
  First number in row 1, second number in row 1, 3rd number in row 1 - line break <br>
  First number in row 1, second number in row 1, 4th number in row 1 - line break <br>
  First number in row 1, second number in row 1, 5th number in row 1 - line break <br></p>
  
  <p>First number in row 2, second number in row 2, 3rd number in row 2 - line break <br>
  First number in row 1, second number in row 1, 4rd number in row 2 - line break <br></p>
  
  <p>and so on........</p>
  
  <p>I'm just having a hard time trying to figure out how to nest these loops.</p>
