1.2.273. Could Be Ternary

This control structure may be replaced by a ternary operator.

Th ternary operator may be shorter and easier to read than the full blown if-then-else structure. Depending on the situation, the null-ternary and the coalesce operator may also be a good alternative.

<?php

// original structure
if (empty($a)) {
    $b = 1;
} else {
    $b = foo();
}

// ternary version :
$b = empty($a) ? 1 : foo();

?>
