組合多個陣列

Question

我有一個運行如下

{ 
"1" : [...], 
"2" : [...] 
} 

有沒有辦法將它們全部組合成一個JSON文件？

Answer 1

您必須爲此編寫一個javascript代碼。

var primarJson = { 

    "1" : [1, 2,3,4], 
    "2" : [5, 6,7,8], 
    "3" : [9, 10,11,12], 
    "4" : [13, 14,15,16] 
} 
var combinedJson = { "final" : []} 
for(var i in primarJson){ 

    combinedJson.final = combinedJson.final.concat(primarJson[i]); 

} 

Answer 2

<?php 

$primarJson = '{ 

    "1" : [1, 2,3,4], 
    "2" : [5, 6,7,8], 
    "3" : [9, 10,11,12], 
    "4" : [13, 14,15,16] 
}'; 

$finalArray = json_decode('{"final" : []}', true); 


foreach (json_decode($primarJson) as $key => $value) { 
    $finalArray['final'] = array_merge($value, $finalArray['final']); 
} 


print_r(json_encode($finalArray));
