    // text. (But don't include any characters that would need to be escaped in a regex).

// Construct regex alternation syntax for all the keywords.
    // E.g: (Kathryn Kuhlman|Max KANTCHEDE|Another one)
    $alt_keywords = '('.join('|', array_keys($keywords)).')';

// Double quotes: Prepend marker to keywords in href="...", alt="..." or title="..."
    $text = preg_replace(
        '/((?:href|alt|title)\s*=\s*"[^"]*)'.$alt_keywords.'/',

// Optional step - not explicitly requested in the question but seems necessary:
    // Prepend marker to keywords found within anchor tags / end tags: <a>...</a>
    $text = preg_replace(
        "/(<a(?:\s+[^>]*)?>[^<]*)$alt_keywords([^<]*<\/a\s*>)/",

          "<a href=\"$url\" title=\"$name\">$name</a>",
          $text);
    }

// Now clean up by removing all instances of the marker text:
    $text = str_replace($marker, '', $text);
