php sloučit pole json

Podrobné vysvětlení

Budu zvažovat json_objects takto na základě kódu PHP.

<?php
$array1 = '[
{"PlayerID":"17794204","userName":"Vandiel","castleCount":"9","NotUpd":"1476253231000"},
{"PlayerID":"21532584","userName":"Mayland","castleCount":"1","NotUpd":"0"},
{"PlayerID":"21539896","userName":"Dana","castleCount":"9","NotUpd":"0"}
]';
$array2 = '[
{"PlayerID":"17794204","Trouble":"2"},
{"PlayerID":"21532584","Trouble":"0"},
{"PlayerID":"21539896","Trouble":"0"}
]';
?>

Abychom tedy mohli sloučit json_objects, musíme nejprve použít json_decode() pro obě pole, která jsme získali.

$decode_one = json_decode($array1,TRUE);
$decode_two = json_decode($array2,TRUE);

Proto výstup pro json_decoded() řetězec bude následující.

První dekódovaný řetězec:

Array ( [0] => Array ( [PlayerID] => 17794204 [userName] => Vandiel [castleCount] => 9 [NotUpd] => 1476253231000 ) [1] => Array ( [PlayerID] => 21532584 [userName] => Mayland [castleCount] => 1 [NotUpd] => 0 ) [2] => Array ( [PlayerID] => 21539896 [userName] => Dana [castleCount] => 9 [NotUpd] => 0 ) ) 

Druhý dekódovaný řetězec:

Array ( [0] => Array ( [PlayerID] => 17794204 [Trouble] => 2 ) [1] => Array ( [PlayerID] => 21532584 [Trouble] => 0 ) [2] => Array ( [PlayerID] => 21539896 [Trouble] => 0 ) )

Funkce pro kód je tedy následující.

Zvažoval jsem ID hráče jako UNIQUE Parametr a zkombinoval pole.

function merge_json_decoded_arrays($decode_one,$decode_two) {
    $data = array();
    $arrayAB = array_merge($decode_one,$decode_two);
    foreach ($arrayAB as $value) {
      $id = $value['PlayerID'];
      if (!isset($data[$id])) {
        $data[$id] = array();
      }
      $data[$id] = array_merge($data[$id],$value);
    }
    return $data;
  }

Tuto funkci musíte zavolat z kódu, kde potřebujete provést array_merge() operace.

$merged_array = merge_json_decoded_arrays($decode_one,$decode_two);

Nakonec se celý kód zobrazí takto s nastavením.

Úplný kód:

<?php
$array1 = '[
{"PlayerID":"17794204","userName":"Vandiel","castleCount":"9","NotUpd":"1476253231000"},
{"PlayerID":"21532584","userName":"Mayland","castleCount":"1","NotUpd":"0"},
{"PlayerID":"21539896","userName":"Dana","castleCount":"9","NotUpd":"0"}
]';
$array2 = '[
{"PlayerID":"17794204","Trouble":"2"},
{"PlayerID":"21532584","Trouble":"0"},
{"PlayerID":"21539896","Trouble":"0"}
]';

$decode_one = json_decode($array1,TRUE);
$decode_two = json_decode($array2,TRUE);

function merge_json_decoded_arrays($decode_one,$decode_two) {
    $data = array();
    $arrayAB = array_merge($decode_one,$decode_two);
    foreach ($arrayAB as $value) {
      $id = $value['PlayerID'];
      if (!isset($data[$id])) {
        $data[$id] = array();
      }
      $data[$id] = array_merge($data[$id],$value);
    }
    return $data;
  }
$merged_array = merge_json_decoded_arrays($decode_one,$decode_two);
?>

Chcete-li zobrazit sloučené pole, musíte print_r() pole a zobrazit jej.

Výstupní kód pole:

print_r($merged_array);

Výstup:

Array ( [17794204] => Array ( [PlayerID] => 17794204 [userName] => Vandiel [castleCount] => 9 [NotUpd] => 1476253231000 [Trouble] => 2 ) [21532584] => Array ( [PlayerID] => 21532584 [userName] => Mayland [castleCount] => 1 [NotUpd] => 0 [Trouble] => 0 ) [21539896] => Array ( [PlayerID] => 21539896 [userName] => Dana [castleCount] => 9 [NotUpd] => 0 [Trouble] => 0 ) )

Pokud jej potřebujete jako výstup JSON, musíte json_encode() získané array() a provádět operace.

Výstupní kód JSON:

print_r(json_ecode($merged_array));

Výstup:

{"17794204":{"PlayerID":"17794204","userName":"Vandiel","castleCount":"9","NotUpd":"1476253231000","Trouble":"2"},"21532584":{"PlayerID":"21532584","userName":"Mayland","castleCount":"1","NotUpd":"0","Trouble":"0"},"21539896":{"PlayerID":"21539896","userName":"Dana","castleCount":"9","NotUpd":"0","Trouble":"0"}}

Nejrychlejší způsob provedení bude trvat tímto způsobem

Musíte dekódovat json_strings a pak je musíte oba prohodit pomocí foreach() a poté zkombinujte s array() že se k němu musíte připojit.

$decode_one = json_decode($array1,TRUE);
$decode_two = json_decode($array2,TRUE);
foreach ($decode_one as $key => $first_value) {
    foreach ($decode_two as $key_two => $second_value) {
        if($first_value['PlayerID']==$second_value['PlayerID'])
        { $decode_one[$key]['Trouble'] = $second_value['Trouble'];//Here if the key exists it will join the Trouble with the First decoded array }
        else {}
    }
}
$combined_output = json_encode($decode_one); //This will return the output in json format.

Výstup:

[{"PlayerID":"17794204","userName":"Vandiel","castleCount":"9","NotUpd":"1476253231000","Trouble":"2"},{"PlayerID":"21532584","userName":"Mayland","castleCount":"1","NotUpd":"0","Trouble":"0"},{"PlayerID":"21539896","userName":"Dana","castleCount":"9","NotUpd":"0","Trouble":"0"}]
