PHP如何递归将对象转化成数组，并且递归去除键名
在PHP当你获得一个多维对象时（你也不知道它最多有几维），你需要将它转换成数组，有时候你还需要将它前面 "key" 去除。例子如下：
{
"status":1,
"data":{
"104":{
"id":"104",
"parent_id":"0",
"value":"CPLB000047",
"label":"所有类别",
"children":{
"105":Object{...},
"106":{
"id":"106",
"parent_id":"104",
"value":"CPLB000048",
"label":"工业继电器",
"children":{
"107":{
"id":"107",
"parent_id":"106",
"value":"CPLB000049",
"label":"常规继电器",
"children":{
"112":{
"id":"112",
"parent_id":"107",
"value":"CPLB000054",
"label":"小型电磁式继电器",
"children":[
]
},
"113":{
"id":"113",
"parent_id":"107",
"value":"CPLB000055",
"label":"接触器式继电器",
"children":[
]
},
"114":{
"id":"114",
"parent_id":"107",
"value":"CPLB000056",
"label":"接口继电器",
"children":[
]
},
"115":{
"id":"115",
"parent_id":"107",
"value":"CPLB000057",
"label":"固态继电器",
"children":[
]
},
"116":{
"id":"116",
"parent_id":"107",
"value":"CPLB000058",
"label":"印刷基板用继电器",
"children":[
]
}
}
},
"108":Object{...},
"109":Object{...},
"110":Object{...},
"111":Object{...}
}
}
}
}
},
"message":"获取成功"
}转换成这样子：
{
"status":1,
"data":[
{
"id":"104",
"parent_id":"0",
"value":"CPLB000047",
"label":"所有类别",
"children":[
Object{...},
{
"id":"106",
"parent_id":"104",
"value":"CPLB000048",
"label":"工业继电器",
"children":[
{
"id":"107",
"parent_id":"106",
"value":"CPLB000049",
"label":"常规继电器",
"children":[
{
"id":"112",
"parent_id":"107",
"value":"CPLB000054",
"label":"小型电磁式继电器",
"children":[
]
},
{
"id":"113",
"parent_id":"107",
"value":"CPLB000055",
"label":"接触器式继电器",
"children":[
]
},
{
"id":"114",
"parent_id":"107",
"value":"CPLB000056",
"label":"接口继电器",
"children":[
]
},
{
"id":"115",
"parent_id":"107",
"value":"CPLB000057",
"label":"固态继电器",
"children":[
]
},
{
"id":"116",
"parent_id":"107",
"value":"CPLB000058",
"label":"印刷基板用继电器",
"children":[
]
}
]
},
Object{...},
Object{...},
Object{...},
Object{...}
]
}
]
}
],
"message":"获取成功"
}你需要将前面的 "key"，比如 104,105,106...，同时将对象都替换成了数组。你可以使用下面这个PHP方法，实现递归将对象转化成数组，并且递归去除键名：
/**
* Function: 递归将对象转换成数组
* User: chengcheng
* Date: 2018/1/23 16:08
* Return: 对象替换成数组
*/
public function objectToArray($object){
$array = array_values($object);
foreach($array as $k=>$v){
if( gettype($v['child'])=='object' || gettype($v['child'])=='array' ){
$array[$k]['child']=array_values(self::objectToArray($v['child']));
}
}
return $array;
}注：这里我还递归替换了键名，你可以看这里 PHP中递归替换多维数组键名和键值方法。
