WordPress PHP Extended Classes Refer to 'Wrong' Static Variables -


i have wordpress plugin 2 extended classes, area , loc, each of has helper function get. each class has static variables table_name. if call loc::get($id) directly, works expected. if, however, call loc::get($id) area, uses table_name area rather location.

can explain how correct this? regards, 

class _base {     function get($id) {         $instance = new self();         $sql = "select * " . static::$table_name . " id=$id";         return $sql;     } }  class area extends _base {     static $table_name = "area";     function getloc($id) {         $sql = loc::get($id);         return $sql;     } }  class loc extends _base {     static $table_name = "loc"; } 
$sql = area::get(1); // -> "select * **area** id=1"  $sql = loc::get(1); // -> "select * **loc** id=1"  $sql = $area->getloc(1); // -> "select * **area** id=1"

i think problem run non static method get static. when changed start work fine. try code below:

<?php class _base {     static function get($id) {         $instance = new self();         $sql = "select * " . static::$table_name . " id=$id";         return $sql;     } }  class area extends _base {     static $table_name = "area";     function getloc($id) {         return loc::get($id);     } }  class loc extends _base {     static $table_name = "loc"; }  var_dump(area::get(1)); var_dump(loc::get(1)); var_dump((new area)->getloc(1));
