Question

I have a text with ‘a’ tags there. I have to add some new tags and attributes.

It looks like this:

'Some test <a href="site">here</a>. Yet <a href="site2">another</a> test.'

Now I have to get:

'Some test <noindex><a rel="nofollow" href="site">here</a></noindex>.'
'Yet <noindex><a rel="nofollow" href="site2">another</a></noindex> test.'

Any fast ways to do that with php? Thanks.

Something like this would cover most real world cases:

$text = 'Some test <a href="site">here</a>. Yet <a href="site2">another</a> test.';

$regex = '%(<a\s)(.*?</a>)%i';
$replacement = '<noindex>$1rel="nofollow" $2</noindex>';

preg_replace($regex, $replacement, $text);
