How to set title of PHP page?

Question

PHP

There is a small problem when I want to set the title of the page through PHP - <?php echo $item->name; ?>
gives an error, although when I write $cat_title (category name) everything is fine. Please help, how can $item->name be converted into a variable to insert into the title

Answer 1

look first what's in it

<?php
print_r($item);
?>
