This issue has been corrected for the (in-progress) Zen Cart 1.5.6 release by the following insertion into /includes/classes/categories_ul_generator.php's BuildBranch function:

function buildBranch($parent_id, $level = 0, $submenu=true, $parent_link='')
 {
        [B] $level = (int)$level;[/B]
         $result = sprintf($this->parent_group_start_string, ($submenu==true) ? ' class="level'. ($level+1) . '"' : '' );
         
         if (($this->data[$parent_id])) {

my experience with later versions of php7 require the casting back to a string.

function buildBranch($parent_id, $level = 0, $submenu=true, $parent_link='')
 {
         $level = (int)$level;
         $result = sprintf($this->parent_group_start_string, ($submenu==true) ? ' class="level'. (string)($level+1) . '"' : '' );
         
         if (($this->data[$parent_id])) {

You should submit a PR, then, since the code I posted is the current version on the Zen Cart v156 GitHub.

my mistake... i am not able to replicate the error using php7.1 or php7.2.

Thank you!
After i find this
https://www.zen-cart.com/showthread.php?222638-PHP-Warning-A-non-numeric-value-encountered-PHP-7-warnings
i changed categories_ul_generator.php with ...el'. (float)($level+1) . '"... that is correct? Or must change again with (string)?

Now i changed and /includes/modules/pages/advanced_search_result/header_php.php:
$rate = $currencies->get_value($_SESSION['currency']);
if ($rate) {
$pfrom = (float)$_GET['pfrom'] / $rate;
$pto = (float)$_GET['pto'] / $rate;
}

no need to add string.

best.

Thank you!
