That is a shorthand way of writing an if statement..

$variable = (statement) ? "return if true" : "return if false";

//# Compared to

if(statement) {
    $variable = "return this if true"; 
} else { 
    $variable = "return this if false";
}

$var ? $var : ' '

 

if $var is set, then echo $var, else echo ' '

 

you would need an echo in front of $var though

It's called a ternary statement.

 

alco19357, that's not exactly true. It's not so much if $var is set, but more like if (bool) $var is true. It doesn't exactly echo. It really depends on what's before the ternary statement in that line.
