title: PHP Regex with parentheses
body: <p>I have the below string:</p>
  
  <pre><code>test 13 (8) end 12 (14:48 IN 1ST)
  </code></pre>
  
  <p>I need the output to be:</p>
  
  <pre><code>14:48 IN 1ST
  </code></pre>
  
  <p>or everything inside parentheses towards the end of the string.</p>
  
  <p>I don't need, 8 which is inside first set of parentheses. There can be multiple sets of parentheses in the string. I only need to consider everything inside the last set of parentheses of input string.</p>
