title: I need help applying a limit to a Regular expression on php
body: <p>I am trying to find a number that consists of only 8 numbers, this is the code I have already:</p>
  
  <pre><code>preg_match_all("/([0-9]{8})/", $string, $match)
  </code></pre>
  
  <p>but this pulls 8 numbers from number strings that are longer than 8 digits </p>
  
  <p>any help would be gratefully appreciated</p>
  
  <p>Thanks</p>
