What are some common pitfalls to avoid when working with dynamic breadcrumb navigation in PHP?

One common pitfall when working with dynamic breadcrumb navigation in PHP is not properly updating the breadcrumb trail as the user navigates through the site. To avoid this issue, it is important to update the breadcrumb trail with the correct links and labels based on the user's current page. 

// Example PHP code snippet for updating dynamic breadcrumb navigation

$current_page = "Home"; // Get the current page dynamically
$breadcrumb_trail = array(
    "Home" => "/",
    "Products" => "/products",
    "Category" => "/products/category"
);

// Update breadcrumb trail based on current page
if ($current_page == "Products") {
    $breadcrumb_trail["Products"] = "/products";
} elseif ($current_page == "Category") {
    $breadcrumb_trail["Products"] = "/products";
    $breadcrumb_trail["Category"] = "/products/category";
}

// Display breadcrumb trail
foreach ($breadcrumb_trail as $label => $link) {
    echo "<a href='$link'>$label</a> > ";
}
echo $current_page;
