title: PHP Check if array element exists in any part of the string
body: <p>I know how to find if your string equals an array value:</p>
  
  <pre><code>$colors = array("blue","red","white");
  
  $string = "white";
  
  if (!in_array($string, $colors)) {
      echo 'not found';
  }
  </code></pre>
  
  <p>...but how do I find if the string CONTAINS any part of the array values?</p>
  
  <pre><code>$colors = array("blue","red","white");
  
  $string = "whitewash"; // I want this to be found in the array
  
  if (!in_array($string, $colors)) {
      echo 'not found';
  }
  </code></pre>
