title: PHP Search for string then get next characters
body: <p>I have a string that looks like this:</p>
  
  <pre><code>blah blah blah
  Team ID:&lt;/div&gt;xxxxxxx
  blah blah blah
  </code></pre>
  
  <p>where the x's are a 7 digit number.</p>
  
  <p>How can I search for the "Team ID:" and then get the 7 digit number ahead of it?
  (In php).</p>
