title: find the second occurrence of a char in a string php
body: <p>Imagine i have this string :</p>
  
  <pre><code>$info="portugal,alemanha,belgica,porto 1-0 alemanha, belgica 2-0";
  </code></pre>
  
  <p>I want to know the position of the 2nd char "-", so i want the result 2-0 and not the result 1-0.</p>
  
  <p>I'm using this function, but it's always returning the first position,</p>
  
  <pre><code>$pos = strpos($info, '-');
  </code></pre>
  
  <p>Any idea? Thanks</p>
