title: Add <br> when echo
body: <p>Variable <code>$name</code> (string) gives something like (5 possible values):</p>
  
  <pre><code>"Elton John"
  "Barak Obama"
  "George Bush"
  "Julia"
  "Marry III Great"
  </code></pre>
  
  <p>Want to add <code>&lt;br /&gt;</code> after the first whitespace (" " between words).</p>
  
  <p>So, it should give when echo:</p>
  
  <pre><code>"Elton&lt;br/&gt;John"
  "Barak&lt;br/&gt;Obama"
  "George&lt;br/&gt;Bush"
  "Julia"
  "Marry&lt;br/&gt;III Great"
  </code></pre>
  
  <p>1) <code>&lt;br /&gt;</code> should be added only if there is more than one word in a string.</p>
  
  <p>2) Only after the first word.</p>
  
  <p>3) Can be more than 3 words in variable.</p>
