数组的处理问题，遍历后有的数据不知道哪去了

第一个数组：applyArr

array(8) {

}

想要的结果应该是在最终的结果数组里下标2的安环部里应该有个data元素，应该是applyArr中的0元素
这是处理的代码：

foreach ($applyArr as $key => $value) {
		        	foreach ($value as $k => $v) {
		        		if(is_array($v) && !is_null($v['deptId'])){
		        			if($v['deptId'] == $dept[$key]['id']){
		        				$dept[$key]['data'] = $value;
		        			}
		        		}
		        	}
		        }

不知道问题出在哪啊，大家帮帮忙看看

框住的部分有问题

建议你把dept数组数组先处理先，把id作为一维的键 然后再修改你的代码

foreach ($applyArr as $key => $value) {
    foreach ($value as $k => $v) {
        if(is_array($v) && !is_null($v['deptId'])){
            if(isset($dept[$v['deptId']])){
                $dept[$v['deptId']]['data'] = $value;
            }
        }
    }
}

foreach($dept as $i=>$r) {
  foreach($applyArr as $d) {
    $t = array_filter($d, function($v) use ($r) { return $r['id'] == $v['deptId'];});
    if($t) $dept[$i]['data'] = array_merge(isset($dept[$i]['data']) ? $dept[$i]['data'] : array(), $t);
  }
}
print_r($dept);
