Converting a PHP array to JSON string

Question

I have an array that looks like this:

Array ( 
       [1] => Laravel 
       [2] => Volta 
       [3] => Web 
       [4] => Design 
       [5] => Development 
      )

Now I want to convert this array to a string that has to look like this

data: [{id: 1, text: 'Laravel'},{id: 2, text: 'Volta'},{id: 3, text: 'Web'},...],

You will have to convert the indexed list into subarrays each, if you want to split it into id: and text:. And the shallow answers are incorrect when it comes to the output syntax (unquoted keys), but presumably so are you. — mario

when i do json_encode i get {"1":"Laravel","2":"Volta","3":"Web","4":"Design","5":"Development"}but i need {id: 1, text: 'Laravel'},{id: 2, text: 'Volta'},{id: 3, text: 'Web'} — user1994529

YOu can try

$data = Array(
        1 => "Laravel",
        2 => "Volta",
        3 => "Web",
        4 => "Design",
        5 => "Development"
);

array_walk($data, function (&$item, $key) {
    $item = array("id"=>$key,"text"=>$item);
});

print(json_encode(array("data"=>array_values($data))));

Output

{"data":[{"id":1,"text":"Laravel"},{"id":2,"text":"Volta"},{"id":3,"text":"Web"},{"id":4,"text":"Design"},{"id":5,"text":"Development"}]}
