How can using a multidimensional array improve the efficiency of generating a 2D map in PHP?

Using a multidimensional array can improve the efficiency of generating a 2D map in PHP by allowing you to store and access the map data in a structured manner. This makes it easier to manipulate the map data and perform operations such as checking for collisions, updating tile values, or rendering the map. By organizing the map data into rows and columns within a multidimensional array, you can efficiently iterate through the elements and access specific tiles based on their coordinates.

// Example of using a multidimensional array to generate a 2D map
$map = [
    [0, 0, 0, 0],
    [0, 1, 1, 0],
    [0, 1, 1, 0],
    [0, 0, 0, 0]
];

// Accessing a specific tile on the map
$row = 1;
$column = 2;
$tileValue = $map[$row][$column];
echo "Tile value at row $row, column $column: $tileValue";
