Combining multiple arrays

Question

I have a json file that runs as follows

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

Is there any way to combine them all as one?

Question is unclear. what expected outcome you want? and what code you have tried so for? — Alive to die - Anant, Nov 24 '16 at 05:54
`json_decode()` and `array_merge()`? What have you tried? Expected result? — M. Eriksson, Nov 24 '16 at 05:55

There's just one object there. What do you want to combine it with? — Barmar, Nov 24 '16 at 06:54

You will have to write a javascript code for this.

    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]);

}

The question is tagged PHP, not Javascript. – Barmar Nov 24 '16 at 06:53
oh! My bad for php you can use array_merge for each of the json array object and push them in a fresh array. – Mitesh Pant Nov 24 '16 at 07:05

<?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));

?>
