I'm pretty new to php and I'm trying to figure out the most on my own to learn but been stuck on this problem a little while so decided to ask for help.

Alright, I got a row in my db named "custom". What I want to do with that is something like this.

PHP Code:
If $custom = (empty) {
     
$label = (default value)
} else {
     
$label $custom

It's probably really easy but haven't be able to find any good resources to help me do it myself.
Thanks!
