What potential issues can arise when modifying breadcrumb loops in PHP templates?

Potential issues that can arise when modifying breadcrumb loops in PHP templates include breaking the functionality of the breadcrumbs or causing errors due to incorrect logic or syntax. To solve this, it is important to carefully test any modifications made to the breadcrumb loops to ensure that they are functioning correctly. 

// Example of a basic breadcrumb loop in PHP template
$breadcrumbs = array(
    'Home' => '/',
    'Category' => '/category',
    'Product' => '/category/product'
);

foreach ($breadcrumbs as $label => $url) {
    echo '<a href="' . $url . '">' . $label . '</a> / ';
}
