title: Find only THIS part of the string PHP
body: <p>I have a variable $string with the following layout inside :</p>
  
  <pre><code>image: "http://web.com/files/images/442873_large.jpg",
  thumb: "http://static.web.com/scripts/image.php/60x60/402813.jpg",
  mp3: "http://web.com/files/clip/6240/23121376.mp3",
  waveform: "http://web.com/files/wave/23121376-wf.png"
  </code></pre>
  
  <p>How could I locate and set the url of thumb: to a new variable ie:</p>
  
  <pre><code>$thumb = 'http://static.web.com/scripts/image.php/44x44/442873.jpg';
  </code></pre>
  
  <p>BUT the thumb url (and all of the values) will be different every time the script is run (so I can't match the contents of the actual url).</p>
  
  <p>Basically what function / functions do I need to use to :</p>
  
  <p>1) search the entire string for thumb:</p>
  
  <p>2) select everything in between the directly following quotation marks</p>
  
  <p>3) store the result to a variable (without the "")</p>
