What are some best practices for efficiently searching and manipulating multidimensional arrays in PHP?

When searching and manipulating multidimensional arrays in PHP, it is important to use efficient methods to avoid unnecessary loops and iterations. One way to efficiently search multidimensional arrays is by using array functions like array_search() or array_column(). Additionally, manipulating arrays can be done using functions like array_map() or array_filter() to apply operations to each element in the array. 

// Example of efficiently searching a multidimensional array using array_search()
function searchMultidimensionalArray($array, $searchValue) {
    foreach ($array as $key => $subarray) {
        $index = array_search($searchValue, $subarray);
        if ($index !== false) {
            return [$key, $index];
        }
    }
    return false;
}

// Example of efficiently manipulating a multidimensional array using array_map()
$numbers = [[1, 2, 3], [4, 5, 6], [7, 8, 9]];
$multipliedNumbers = array_map(function($subarray) {
    return array_map(function($num) {
        return $num * 2;
    }, $subarray);
}, $numbers);
