title: Convert backslash-delimited string into an associative array
body: <p>I have a string like this:</p>
  
  <pre><code>key1\value1\key2\value2\key3\value3\key4\value4\key5\value5
  </code></pre>
  
  <p>And I'd like it to be an associative array so that I can do:</p>
  
  <pre><code>echo $myArray['key1']; // prints value1
  echo $myArray['key3']; // prints value3
  //etc...
  </code></pre>
  
  <p>I know I can explode on the backslash, but not sure how to go from there.</p>
