php – Remove "header" value json

Question:

I have a problem to generate a json in php, after the query it returns this

{"37":{"codigo":"37","firstname":"Aluno","lastname":"Toledo","atividade":"A","checklist":null},
"1475":{"codigo":"1475","firstname":"Alzira","lastname":" Cabral","atividade":"A","checklist":"C"}}

is there how I can remove the "37" and the "1475"??

because I want to solve this problem, when I call it in an http.get by angular, it's sorting by this json "header"…

Answer:

<?php

$array = json_decode('{"37":{"codigo":"37","firstname":"Aluno","lastname":"Toledo","atividade":"A","checklist":null},
                       "1475":{"codigo":"1475","firstname":"Alzira","lastname":" Cabral","atividade":"A","checklist":"C"}}', 1);

$result = array();   

foreach ($array as $key => $value) 
{
    $result[] = $value;
}

echo json_encode($result);
