php class static variables ,concat -

-

is have 2 class

first 

<?php    require_once( 'error/disconnectedhandler.php' );   require_once( 'error/nosuchrequesthandler.php' );     class networkmanager {    public static final $response_jump = 1000;   ....

second 

<?php     require_once( '../networkmanager.php' );      class disconnectedhandler implements handler{         public static $type          = 2000;         public static $response_type = self::$type + networkmanager::$response_jump;         public static $ver           = 0;

i error in line 

public static $response_type = self::$type + networkmanager::$response_jump;

eclipse ide paint $type in red , says 

multiple annotations found @ line: - syntax error, unexpected '$type', expecting   'identifier' - syntax error, unexpected '$type', expecting   'identifier'

what correct syntax ?

thank in advanced

static variable declarations (as class constants) must literally defined , cannot contain expression evaluated prior runtime.

you have initialize disconnectedhandler::$respone_type in constructor or more in static initializer method.
