How can arrays be utilized in PHP to efficiently store and access user-specific data such as favorite links?

To efficiently store and access user-specific data such as favorite links in PHP, arrays can be utilized. Each user can have their own array where their favorite links are stored. This allows for easy access and manipulation of the data for each user. 

// Example of storing and accessing favorite links for a specific user
$userFavorites = [];

// Add favorite links for user
$userFavorites['user1'] = ['https://example.com', 'https://google.com', 'https://stackoverflow.com'];

// Access favorite links for user
foreach ($userFavorites['user1'] as $link) {
    echo $link . "<br>";
}
