Concatenate a Link in PHP using single quotes

Recommended Posts

Hi all,

 

I have the following PHP code block:

<?php
  $website = "http://www.nationalgeographic.com";

  echo 'Catch up on all the latest, visit: <a href=" ' . $website .' ">National Geographic</a>'; //works
  echo "<br><br>";
 
  echo 'Catch up on all the latest, visit: <a href= ' . $website .' >National Geographic</a>'; //works 
  echo "<br><br>";
 
 echo 'Catch up on all the latest, visit: <a href="  . $website . ">National Geographic</a>'; // Does not work
 ?>
 

 

Why do examples 1 and 2 only work and which is the best option to go with, if any, around the <a href="">?

 

i.e. <a href=" ' . $website . ' "> or <a href= ' . $website . ' > or does it matter?

 

Thanks,

 

Andy ;-)
