Rearrange array index Eloquent Laravel
提问by Miguel
I have an error after delete an element from an array of laravel eloquent
从 Laravel eloquent 数组中删除一个元素后出现错误
A property has rooms
一个属性有房间
foreach ($property->rooms as $key => $room) {
if ($room->type == 1 and $type ==1 and $room->price < $price->min or $room->price > $price->max) {
print_r($property->rooms);
unset($property->rooms[$key]);
//$array = array_values($property->rooms); doesn't work
print_r($property->rooms);
}
}
When i encode this into a json, the array is convert into an object not an array
当我将其编码为 json 时，数组将转换为对象而不是数组

converted into a json the rooms field should be an array not an object:
转换为 json 的房间字段应该是一个数组而不是一个对象：
{"other_parameters": "something","rooms":{"1":{"id":2,"properties_id":4,"price":350000,"is_available":1,"created_at":"-0001-11-30 00:00:00","updated_at":"2014-10-21 18:13:15","type":1,"description":null},"2":{"id":3,"properties_id":4,"price":250000,"is_available":1,"created_at":"-0001-11-30 00:00:00","updated_at":"-0001-11-30 00:00:00","type":1,"description":""}}}
回答by Miguel
I have found a solution in the laravel documentation.
我在 laravel 文档中找到了解决方案。
after modifying the array, you have to call a method from laravel collection named values() that arrange the array indexes, example:
修改数组后，您必须从名为 values() 的 laravel 集合中调用一个方法来排列数组索引，例如：
unset($property->rooms[$key]);
$property->rooms->values();
回答by Gustonez
Option 1
选项1
$array = array();
foreach ($property->rooms as $key => $room) {
if ($room->type == 1) {
unset($property->rooms->{$key}); <<-- pay attention to this
} else {
$array[] = get_object_vars($room); // sort the passed row into new array
}
}
print_r($array);
Option 2
选项 2
To convert from JSON to Array set the assoc flag to TRUE:
要将 JSON 转换为数组，请将 assoc 标志设置为TRUE：
json_decode('Your json script', true);
foreach ($property['rooms'] as $key => $room) {
if ($room['type'] == 1) {
unset($property['rooms'][$key]);
}
}
$array = array_values($property['rooms']);
print_r($array);
