Are there best practices for efficiently managing meta tags in PHP to avoid duplication and optimize storage space?

When managing meta tags in PHP, it is important to avoid duplication and optimize storage space by storing unique meta tags only. One way to achieve this is by using an array to store meta tags and checking for duplicates before adding a new tag. 

// Initialize an array to store meta tags
$metaTags = [];

// Function to add meta tags, avoiding duplicates
function addMetaTag($tag) {
    global $metaTags;
    
    // Check if the tag already exists in the array
    if (!in_array($tag, $metaTags)) {
        $metaTags[] = $tag;
    }
}

// Example of adding meta tags
addMetaTag('description');
addMetaTag('keywords');

// Output meta tags
foreach ($metaTags as $tag) {
    echo "<meta name='$tag' content=''>";
}
