Question
I found this line of code and I'm trying to comprehend what it's doing. The part I'm not familiar with is the question mark and the colon. What are these characters used for?
$string = $array[1] . ($array[0] === 47 ? '' : ' word');
Solution
That's a ternary operator; basically a short-hand conditional.
It's the same as:
$string = $array[1];
if ($array[0] !== 47)
$string .= ' word';
See this section in the PHP manual (the "Ternary Operator" section).
OTHER TIPS
That's the ternary operator.
Here's a reference to a tutorial
It works somehow like this:
function tern()
if ($array[0] === 47)
{
return '';
}
else
{
return 'word';
}
}
