PHP数组分级,万般无奈,救助
array (
array("level" => '1', "caption" => "一级菜单1"),
array("leve1" => '1', "caption" => "一级菜单2"),
array("leve1" => '2', "caption" => "二级菜单1"),
array("leve1" => '2', "caption" => "二级菜单2"),
array("leve1" => '1', "caption" => "一级菜单3"),
)
其中level = 2为其上方最近leve1 = 1 的子菜单,不排除会有level = 3的子菜单(从属于level = 2)现在想弄成下面的形式,想了好久也没什么好方法,同事建议我用递归,可递归小弟不太懂,PHP初接触,给各位大拿添麻烦了
array (
array("level" => '1', "caption" => "一级菜单1"),
array("leve1" => '1', "caption" => "一级菜单2",
"sub"=>array("leve1" => '2', "caption" => "二级菜单1"),
"sub"=>array("leve1" => '2', "caption" => "二级菜单2")
),
array("leve1" => '1', "caption" => "一级菜单3"),
)
