1. 首先定义一个函数:
function nav_select($navindex){ ???$nav_arr = [ ???????1 => [‘index‘,], ???????2 => [‘mei‘,], ???????3 => [‘quan‘,‘write‘], ???????4 => [‘my‘,], ???]; ???$navarr = $nav_arr[$navindex]; ???if(in_array(ACTION_NAME, $navarr)){ ???????echo ‘ nav-on ‘; ???}}
2. 然后在模板里调用：
<a href=‘xxx‘ class=‘{:nav_select(1)}‘>导航1</a>;
php选中导航菜单
