This library if for obtaining content for the META TAGS like keywords, description and also for computing tags to be used in searches based on the given text.

http://www.worldsview.com/metataggen_library.zip

PHP code:

function is_email($email){   $x = '\d\w!\#\$%&\'*+\-/=?\^_`{|}~';    //just for clarity

   return count($email = explode('@', $email, 3)) == 2       && strlen($email[0]) < 65       && strlen($email[1]) < 256       && preg_match("#^[$x]+(\.?([$x]+\.)*[$x]+)?$#", $email[0])       && preg_match('#^(([a-z0-9]+-*)?[a-z0-9]+\.)+[a-z]{2,6}.?$#', $email[1]);}

When in need to change the order of a list use a field to store the order as an int:
Change the order of the records by switching the order value between consecutive elements.

case 'orderdown':case 'orderup':{ //get all list and retain two elements: if moveup operation then I keep prev and current  //otherwise I keep current and next $rec_list = $this->getChildren($record->id_parent);//all records on this level $switch = array(); for($i = 0; $i < count($rec_list) ; $i++){  if($rec_list[$i]['id'] == $record['id']){   if('orderup' == $what && $i != 0){    //not first    $switch[$rec_list[$i-1]['id']] = $rec_list[$i]['corder'];    $switch[$rec_list[$i]['id']] = $rec_list[$i-1]['corder'];    break;   }elseif('orderdown' == $what && $i != (count($rec_list)-1)){    //not last    $switch[$rec_list[$i+1]['id']] = $rec_list[$i]['corder'];    $switch[$rec_list[$i]['id']] = $rec_list[$i+1]['corder'];    break;   }  } }
   
   //valid elements found. Switch them if(count($switch) > 0){  foreach ($switch as $id=>$corder) {   $sql = "UPDATE page SET corder=$corder WHERE$id";   $result = mysql_query($sql) or die("SQL ERROR " . mysql_error() . " [$sql] on " . __FILE__ . " at line " . __LINE__);  } }
