Just plain recursive call should be sufficient here.
function printCategoryName($categories, $parentName = '') {
foreach ($categories as $category) {
$name = $parentName ? implode(' > ', [$parentName, $category->name]) : $category->name;
echo sprintf('%s%s', $name, PHP_EOL);
if (count($category->children) > 0) {
printCategoryName($category->children, $name);
}
}
}
printCategoryName($categories);

@bugsysha the method works, but the childs outputting twice like :
i mean it does output like : Electronics > Laptop but it also outputs like a parent category.

@amrsubzero then you are probably fetching all categories. Try fetching all categories which do not have parent_id.
