I have a code: $html = ‘<html> <body> <p><a href=[LINK]>[LINK]</a></p> <p><img src=[IMAGE] alt=something /></p>

I have a code:

$html = '<html>
            <body>
                <p><a href="[LINK]">[LINK]</a></p>
                <p><img src="[IMAGE]" alt="something" /></p>
                <p>Language specific string: [ANOTHER TAG]</p>
            </body>
         </html>';
$search = array('[LINK]', '[IMAGE]');
$replace = array($post['link'], $post['image']);
$html = str_replace($search, $replace, $html);

Above will replace [LINK] and [IMAGE] with corresponding $post values – this is good when both values are not empty. I need a way to hide the corresponding paragraph when one or more $post values are empty. Anyone has an idea what would be the most efficient solution?
$html content is loaded using file_get_contents (the above is just an ilustration of its content).

EDIT: Since in the $html I also have “localized” strings, I’d rather use the solution that doesn’t force me to replace the whole paragraph. There was a good answer that used DOM manipulation but the author has deleted it…

    $html = '<html>
            <body>
                [LINK]
                [IMAGE]
            </body>
         </html>';
$search = array('[LINK]', '[IMAGE]');
$replace = array(
  (!empty($post['link'])) ? "<p><a href=\"{$post['link']}\">{$post['link']}</a></p>" : '', 
  (!empty($post['image'])) ? "<p><img src=\"{$post['image']}\" alt=\"something\" /></p>" : ''
);
$html = str_replace($search, $replace, $html);

    Now [LINK] and [IMAGE] are replace with the whole tag if they are present, and an empty string if not.

    Depending on how you generate the $post array, you may need to use some condition other than empty() to determine whether they are present, but you get the idea.

    EDIT

    Since these appear to be email template files, I would suggest using the templating functionality of PHP and put some PHP code inside the templates.

    Template file

    <html>
  <body>
<?php if (!empty($post['link'])) { ?>
    <p><a href="<?php echo $post['link']; ?>"><?php echo $post['link']; ?></a></p>
<?php } if (!empty($post['image'])) { ?>
    <p><img src="<?php echo $post['image']; ?>" alt="something" /></p>
<?php } if (!empty($post['another_tag'])) { ?>
    <p>Language specific string: <?php echo $post['another_tag']; ?></p>
<?php } ?>
  </body>
</html>

    PHP script

    ob_start();
include('template.html');
$html = ob_get_clean();
