appending content to json file using php script - php

Question

I am trying to append content to json file using php script.
output of file1 is
[
{"id":"filters","name":"filter_supptype_cp_01"}
]
output of file2 is
[
{"id":"drives","name":"hddcntrlr"},
{"id":"drives","name":"diskdrivedes"}
]
after appending the output should come as :
[
{"id":"filters","name":"filter_supptype_cp_01"},
{"id":"drives","name":"hddcntrlr"},
{"id":"drives","name":"diskdrivedes"}
]
but output is coming as : -
[
{"id":"filters","name":"filter_supptype_cp_01"}]
[{"id":"drives","name":"hddcntrlr"},
{"id":"drives","name":"diskdrivedes"}
]
Code that I have tried is:
$file = file_get_contents('makejson.json');
$data = json_decode($file);
$info[] = array('id'=>$attribute1, 'name'=>$sub_attr_name);
$newb = array_values((array)$info);
file_put_contents('makejson.json',json_encode($newb),FILE_APPEND);
please help!!!!

Answer 1

Decode both files, append the array, encode again:
$existingData = json_decode(file_get_contents('file1.json'));
$newData = json_decode(file_get_contents('file2.json'));
$existingData = array_merge($existingData, $newData);
file_put_contents('file1.json', json_encode($existingData));

Answer 2

The array_push() function inserts one or more elements to the end of an array.
Your code :
$file = file_get_contents('makejson.json');
$tempArray = json_decode($file);
array_push($tempArray, $data); // $data is your new data
$jsonData = json_encode($tempArray);
file_put_contents('makejson.json', $jsonData);

$data[] = $yourdata;
file_put_contents('data.json', json_encode($data));
unset($data); }

Answer 4

You don't need to append array. You need to overwrite it.
Try like:
$file = file_get_contents('makejson.json');
$data = json_decode($file);
$data[] = array('id'=>$attribute1, 'name'=>$sub_attr_name);
file_put_contents('makejson.json',json_encode($data)); //Overwrite it
It will overwrite with new array.
