How can array_map be utilized to format tag links in PHP?

When working with tag links in PHP, you may want to format them in a specific way before displaying them. One way to achieve this is by using the array_map function to iterate through an array of tags and apply a formatting function to each tag. This allows you to customize the output of each tag link according to your requirements. 

// Array of tags
$tags = ['PHP', 'HTML', 'CSS', 'JavaScript'];

// Function to format tag links
function formatTag($tag) {
    return '<a href="/tags/' . strtolower($tag) . '">' . $tag . '</a>';
}

// Using array_map to format tag links
$formattedTags = array_map('formatTag', $tags);

// Output formatted tag links
echo implode(', ', $formattedTags);
