title: How to display "..." (3 dots) if a sentence takes more than 2 lines in php?
body: <p>I looked all over online for this but could not find. I only found for those that use string longer than a specific number defined but I need to display those dots if the sentence takes more than 2 lines.</p>
  
  <p>For example, sentence below is long :</p>
  
  <p><em>The Eiffel Tower is a wrought iron lattice tower on the Champ de Mars in Paris, France. It is named<br> after the engineer Gustave Eiffel, whose company designed and built the tower. The tower is 324 <br>metres (1,063 ft) tall, about the same height as an 81-storey building, and the tallest structure in<br> Paris. Its base is square, measuring 125 metres (410 ft) on each side.</em></p>
  
  <p>I would like to display the above sentence as:</p>
