Make anchors from urls and email addresses

hjalli (Hjalmar Gislason) — Thu, 01 Sep 2005 02:44:51 GMT

This little PHP function will find urls and email addresses in a block of text and turn them into hyperlinks and mailto: anchors respectively.



function makeLinks($sourceText) {

  $destText = preg_replace( "/([_a-zA-Z0-9-]+)(\.[_a-zA-Z0-9-]+)*@([a-zA-Z0-9-]+)(\.[a-zA-Z0-9-]+)*(\.[a-zA-Z]{2,4})/", '\\0',$sourceText);

  $destText = preg_replace_callback('/\bhttp[^\s]+/',create_function('$matches', 'return "" . preg_replace("#(\.|/)#", "$1", $matches[0]) . "";'),$destText);

  return $destText;

}

Tobi posted this as a new URL scheme for Typo.

# allow neat perma urls

map.connect 'articles/:year/:month/:day', :controller  => 'articles', 

     :action => 'find_by_date', 

     :year => /\d{4}/, :day => nil, :month => nil

map.connect 'articles/:year/:month/:day/:title', :controller  => 'articles', 

     :action => 'permalink', :year => /\d{4}/
