还是错了兄弟

＆＃34;这个错误的第30行＆＃34;

public function CheckUser（$ username，$ password）{ $ query = $ this-＆gt; db-＆gt; get_where（$ this-＆gt; table，array（＆＃39; username＆＃39; =＆gt; $ username，＆＃39; password＆＃39; =＆gt; $ password ））; if（$ query-＆gt; num_rows（）＆gt; 0） { 返回true; } else { 返回false;

TMessage：在null上调用成员函数CheckUser（）
