PHP多维数组生成统一下标索引方法

$params = array('tab1'=>
					array('server1'=>array(137, 122),
						  'server2'=>array(100,200)
					),
					'tab2'=>
					array('server3'=>array(400, 500),
						  'server4'=>array(600, 700),
						   'aaa'=>array('bbb'=>array(1,2,3))
					),
					'name' => 'dimain',
					'abc' => array(4,5,6=>array('apple', 'lizi'))
				  );
		
				  
		function test(&$params, &$tmpKeyArr, &$data){
			$i = 0;
			foreach ($params as $k=>&$v){
				$i++;
				if(is_array($v)) {
					$tmpKeyArr[] = '['.$k.']';
					test($v, $tmpKeyArr, $data);
				}else{
					$data[implode($tmpKeyArr, '').'['.$k.']'] = $v;
