Answer 1

Your code needs to be properly formatted so it is readable.

As for the regex, you don't need it, you can use strip_tags() with the second parameter:

$text = '<a href="">link<img src=""></a><span>some text</span>';

echo strip_tags($text, '<a><img>');

The second parameter in strip_tags tells the function what tags you want to keep, in this case, tags and tags.

That is to replace actual tags.

To replace words, use str_ireplace()

$text = 'this is a link, this is an image';

echo str_ireplace('this', 'new word', $text);

// Outputs:
    new word is a link, new word is an image
