php三维数组变二维数组

 Array(0 => Array(bid => 41,brealname => 'we教官',cid => 41,crealname => 'we教官')),
					1 => Array(0 => Array(bid => 6,brealname => '虎子',cid => 19,crealname => '张鱼'))
    );

	//原数组
	print_r($result);

	foreach ($result as $key =>$v){

	//第二种方法
	//初始化$arr2  
	$arr2=array();  
           
	//循环遍历三维数组$arr3
