What does this type of statement mean

[monkeytooth]

$_GET['id'] = (empty($_GET['id'])) ? 0 : $_GET['id'];

 

I'm going over someones code, the site is super flawed, Ive got to much going on at once and I can't wrap my head around that. Is it if the string is empty or 0 then use the get variable or is it something else?

It's a ternary operator.

 

It's a condensed if statement practically.

 

$var = (CONDITIONAL STATEMENT) ? TRUE : FALSE;

It is the ternary operator and is basically a short version of if else.

 

if (empty($_GET['id'])) {
  $_GET['id'] = 0;
} else {
  $_GET['id'] = $_GET['id'];
}

Thats what I thought, I dont typically use statements like that so I wanted to double check with people here, thanks
