Search Category.

[ElijahLoop]

An array of "categories" is given:

    $categories = array(
        array("id" => 1, "title" => "Pants", "children" => array(
            array("id" => 2,
                "title" => "Boots",
                "children" => array(
                    array("id" => 3, "title" => "Leather"),
                    array("id" => 4, "title" => "Textile"),
                ),
            ),
            array("id" => 5, "title" => "Sneakers"),
        ),
        ),
        array(
            "id" => 6,
            "title" => "Sort",
            "children" => array(
                array(
                    "id" => 7,
                    "title" => "Balls",
                ),
            ),
        ),
    );

I need to write a function searchCategory ($categories, $id) that returns the name of the category by the category ID.

Help me please.

Use a recursive function to search subcategories until found

(Pseudocode ti illustrate the logic...)

function searchCategories (category, id, title)
{
    foreach (category as cat) {
        if (this has the id we want) 
            set title value
        else 
            searchCategories(children, id, title)        // calls itself to search sub categories
        end if
    }
}

My test...

$category = $categories;

for ($searchfor = 1; $searchfor <= 8; $searchfor++) {
    $title='Not found';
    searchCategories($category, $searchfor, $title);
    echo "$searchfor - $title<br>";
}

/*
RESULTS
1 - Pants
2 - Boots
3 - Leather
4 - Textile
5 - Sneakers
6 - Sort
7 - Balls
8 - Not found                                    
*/
