I have two variables, $firstname & $lastname

I want to combine them as another variable $realname

So example: if firstname=John &lastname=Smith, then I want realname=John Smith

Would this be the correct usage?

$realname = $firstname & " " & $lastname;
?>

  • Just use dot instead of `&` like this: `$realname = $firstname . " " . $lastname;`. – Amirreza Noori Mar 26 '22 at 03:57

<?php   
    $realname = "$firstname $lastname";
?>

Concatenation in php is achieved by concat operator i.e .

  • OK, Now I'd like to take this one step further and auto add a unique UserName based on the first/lastname... BUT, I need to check the DB for duplicates and append a consecutive number at the end until it is unique. (Example: The second John Smith who registers shoud be John_Smith2, the third John_Smith3, etc.) $username = $firstname . "_" . $lastname; Any ideas? – Roger Rosentreter Mar 26 '22 at 22:51
  • Sorry that should have read John_Smith1 & John_Smith2 for the second and third ones... – Roger Rosentreter Mar 26 '22 at 23:04
