PHP - Concatenate if statement?

Question

I want to concatenate in the middle of an echo to write an if statement, is this possible? Here is what I have.

echo "<li class='".if ($_GET["p"] == "home") { echo "active"; }."'><a href='#'>Home</a>        </li>";

You want [a ternary](http://php.net/manual/en/language.operators.comparison.php). `echo "

I didn't do it but I guess it's because it's something you could have found the answer to by googling. — Popnoodles, Nov 26 '12 at 20:01
Well I came where I trust peoples opinion. Thats not cool lol. — Necro., Nov 26 '12 at 20:02
echo is a language construct. it is not a function and has no return value that you could concatenate. — Marc B, Nov 26 '12 at 20:10

Like this, using the ternary operator:

echo "<li class='". (($_GET["p"] == "home") ? "active" : "") . "'><a href='#'>Home</a>        </li>";

Do like this:

echo "<li class='".($_GET["p"] == "home" ? 'active' : '') ."'><a href='#'>Home</a>        </li>";

Instead of messy inline concatenations, might I suggest getting cozy with printf()?

$format = '<li class="%s"><a href="#">Home</a>        </li>';
printf($format, ($_GET['p'] == 'home') ? 'active' : '');
