title: How to get value of array by using the key from a string
body: <p>I have an array with some keys and I want to get the array values according to the array keys where the keys are in a string.</p>
  
  <p>Example:</p>
  
  <pre><code>$arr = array(
          "COV" =&gt; "Comilla Victorians",
          "RK"  =&gt; "Rajshaji Kings"
      );
  
  $str = "COV-RK";
  </code></pre>
  
  <p>Now I want to show <code>Comilla Victorians VS Rajshaji Kings</code>.</p>
  
  <p>I can do it using some custom looping, But I need some smart coding here and looks your attention. I think there are some ways to make it with array functions that I don't know.</p>
