I am new to PHP and I am trying to convert an array to json, without the indices.
For an example, I have:
[{"name":"Dean"},{"last_name":"Don"},{"age":31},{"height":181}]
I need it to be a single json object:
{
"name":"Dean,
"last_name":"Don",
"age":31,
"height":181
}
I tried using json_encode() but all I get is not correct, I event tried specifying
JSON_FORCE_OBJECT, which put the indices, which I don't want.
Anyone has an idea how to solve it? Thank you
Another way is to decode, merge and recode:
$json = '[{"name":"Dean"},{"last_name":"Don"},{"age":31},{"height":181}]';
$data = json_decode($json,true); // decode
$data = array_merge(...$data); // merge
echo json_encode($data, JSON_PRETTY_PRINT); // recode
Output:
{
"name": "Dean",
"last_name": "Don",
"age": 31,
"height": 181
}
array_merge is perfect for this.did you try
json_encode(array_values($array))?
You can use json_decode to convert the json into an array. Use array_reduce to make a new array. Use json_encode to convert the array into a json again
$str = '[{"name":"Dean"},{"last_name":"Don"},{"age":31},{"height":181}]';
//Convert the json into array
$arr = json_decode($str, true);
//Make the multi dementional array into an associative array
$arr = array_reduce($arr, function($c, $v){
foreach ($v as $key => $val) $c[$key] = $val;
return $c;
}, array());
//Convert the array to json
$result = json_encode($arr);
echo $result;
This will result to:
{"name":"Dean","last_name":"Don","age":31,"height":181}
The first bit of JSON looks like the result of encoding an array of key-value pairs like this:
$data = [
['name' => 'Dean'],
['last_name' => 'Don'],
['age' => 31],
['height' => 181]
];
If that's what you are starting with, you can iterate the set of attributes and construct an entity that will encode to a single object.
foreach ($data as $attribute) {
$entity[key($attribute)] = reset($attribute);
}
echo json_encode($entity);
As mentioned in the comments, there may be a better way to do this earlier in your code, so you can create the entity you want in the first place instead of something like the $data example that you'll have to re-process before you can output it.
