What are the potential pitfalls of using implode and explode functions in PHP to manipulate arrays for navigation menu items?

The potential pitfall of using implode and explode functions in PHP to manipulate arrays for navigation menu items is that it can lead to unexpected results if the delimiter used is present in the menu item titles. To solve this issue, it's better to use a unique delimiter that is not likely to appear in the menu item titles. 

// Example of using a unique delimiter to avoid issues with implode and explode functions
$menuItems = ['Home', 'About Us', 'Services', 'Contact Us'];

// Implode the menu items with a unique delimiter
$implodedMenu = implode('||', $menuItems);

// Explode the imploded menu items using the same unique delimiter
$explodedMenu = explode('||', $implodedMenu);

// Output the exploded menu items
print_r($explodedMenu);
