If null don't print anything

Hi all, i'm doing a project using php for the first time and struggling with it.

certain things are returning "Null"

how can I work this into an if statement

<?=str_replace('height=', 'data-height=',$series['description'])?>

so if null, don't print anything.

you can check if it's null using is_null

try this 

<?php

<? 
if($series['description']!=""){
    $new_string= str_replace('height=', 'data-height=',$series['description']);
   echo  $new_string; 
}   


?>

or 
<? 
if(isset($series['description'])){
    $new_string= str_replace('height=', 'data-height=',$series['description']);
   echo  $new_string; 
}   


?>

so it wont print anything if $series['description'] is null
