How can the issue of skipping every other product with the same category ID be resolved in the PHP script provided?

The issue of skipping every other product with the same category ID can be resolved by keeping track of the previous category ID and only displaying products when the current category ID is different from the previous one. This can be achieved by adding a conditional check in the loop that iterates through the products. 

$previousCategoryId = null;

foreach ($products as $product) {
    if ($product['category_id'] != $previousCategoryId) {
        // Display the product
        echo $product['name'] . "<br>";
        
        // Update the previous category ID
        $previousCategoryId = $product['category_id'];
    }
}
