Rearrange array index Eloquent Laravel

问题:

I have an error after delete an element from an array of laravel eloquent

A property has rooms

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

Before unset

converted into a json the rooms field should be an array not an object:

{"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1:

I have found a solution in the laravel documentation.

after modifying the array, you have to call a method from laravel collection named values() that arrange the array indexes, example:

unset($property->rooms[$key]); $property->rooms->values(); 

回答2:

Option 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

To convert from JSON to Array set the assoc flag to 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);
