用regex改进URL解释

Posted 2021-02-25

A source to help you interpreting URLs in plain text as a html link. It's an improvement of what was proposed here : http://snipplr.com/view/2371/regex-regular-expression-to-match-a-url/

// Returns the text given as parameter, with contained URLs interpreted as HTML links
 
function link($text){
  return preg_replace('@((https?://)?([-w]+.[-w.]+)+w(:d+)?(/([-w/_.]*(?S+)?)?)*)@', '<a href="$1">$1</a>', $text);
}
