Is it possible to reduce this expression to one line?
echo '<li>';
echo $value['name'];
if ($value['childs']) {
echo '<ul>';
echo $this->arrayToString($value['childs']);
echo '</ul>';
}
echo '</li>';
For example:
echo '<li>' . $value['name'] // what to do if statement? ... ;
It deffinitely is possible:
echo '<li>' . $value['name'] . ($value['childs'] ? '<ul>' . $this->arrayToString($value['childs']) . '</ul>' : '') . '</li>';
But I really do not recommend it. I will be much less readable. Maybe reather try to extract one part to another function like this:
function printItem($value)
{
echo '<li>' . $value['name'] . $this->printItemChilds($value) . '</li>';
}
function printItemChilds($value)
{
return $value['childs'] ? '<ul>' . $this->arrayToString($value['childs']) . '</ul>' : '';
}
