PHP doubt with JSON: I already know how to loop a JSON file and show all records and also show only the last record using END. Can I show the last 5, 10 record, for example?

To use a portion of an array, just use array_splice.

$input = array( "vermelho" , "verde" , "azul" , "amarelo" , "preto" , "cinza" );
array_splice( $input , 0 , -5 );
print_r( $input );

output

Array
(
    [0] => verde
    [1] => azul
    [2] => amarelo
    [3] => preto
    [4] => cinza
)

  • It is not to return part of an array. This I know. It is to return an N amount of record of a JSON file, not all records. Got it?

  • That. In the example I returned only the 5 latter.

This is not what I need. I have a JSON file and already know how to loop and return all records. If I just need to last record use the END so:

    $pesquisa = json_decode(file_get_contents("nomedoarquivo"),true);
    $ultimoRegistroPesq = end($pesquisa["registros"]);
    $strCampo = $ultimoRegistroPesq['campo'];

I want to know if you can limit the search to the last 5 records, for example. If you were searching a database I would use LIMIT 5 in the query. But with JSON I don’t know.
