problem with class

[dimis283]

I have a problem with this code

<?php
class Mypdo
{  static $dbh;
   public static function mydbh()
{ if (self::dbh==null)
    {     self::dbh  = new PDO("mysql:host=localhost;dbname=auctions", "dimis", "dimis");}
return self::dbh;
}
}
?>

Parse error: syntax error, unexpected '=' on line 6

What is wrong?

[centered effect]

self::dbh

should be

self::$dbh

[StarLion]

you forgot the $ in front of dbh?
