echo two variables on the one line

Hi, i have a page that echoes my username at the top of the page, however i want to change it to firstname lastname

At the top of the page the following code appears:

<? echo $_SESSION['user_info']['username'];?>


however my firstname and lastname are the following variables. How do output the two of these with just the one echo

firstname = $_SESSION['my_array'][1]
lastname = $_SESSION['my_array'][12]

 

<?php

echo $_SESSION['my_array'][1], ' ', $_SESSION['my_array'][12];

?>

PHP:

 

should there be single or double quotes between them

 

No difference as there are no variables between them.

 

Ok, thanks for your help

 

You could also do:

echo 'First: ' . $_SESSION['my_array'][1] . 'Last ' . $_SESSION['my_array'][12];

 

Is that who you output names?

Besides, you are missing a space.
