Insert a space between 2 echo

Question

How do I add a space in the returned text between sample1 and sample2? Here is what I have so far:

if ($eventid!="") { 
   echo $get_event['sample1'], $get_event['sample2']; 
}

Answer 1

It's really simple, just echo a space between the variables...

<?php if($eventid!=""){echo $get_event['sample1'] , ' ', $get_event['sample2']; }

Answer 2

Indentation always make things cleaner and easier:

if (!empty($eventid)) {
    echo $get_event['sample1'] . ' ' . $get_event['sample2'];
}

On PHP, you need to use a dot (.) to concatenate strings... as you can see on the Strings Operators documentation:
