Convert array into json array using php

Question

I have a PHP array like below:

 Array
(
 [0] => stdClass Object
 (
 [id] => 1
 [area] => Arappalayam
 )
 [1] => stdClass Object
 (
 [id] => 2
 [area] => Kalavasal
 )
)

Now, I need to convert this array into Json array like below :

 $local_source = [
 {
 id: 1,
 area: "Arappalayam"
 }, {
 id: 2,
 area: "Kalavasal"
 }
];

I have tried below code to convert json array in php

$availableArea = array_slice($areas[0],0);
return json_encode($availableArea);

But It is not working, any ideas>?

The result came as like [{"id":"1","area":"Arappalayam"},{"id":"2",area:"Kalavasal"}]; but i want [{id:1,area:"Arappalayam"},{id:2,area:"Kalavasal"}];

• JAL: The problem is that you don't want property names quoted and integers as strings?

Answer 1

You dont need to use array_splice(). Just use:

json_encode($myArray);

Answer 2

1) Your "id":"1" but not "id":1 is because your value in PHP are really strings, not int. Convert them using intval() will have a different result.

2) No. You cannot generate id: rather then "id":, because keys are quoted string in standard JSON specification. Beside, there are Javascript reserved words could be be key in JSON.

Answer 3

simply use json_encode

$local_source = json_encode($array);

check docs http://pk1.php.net/json_encode

and when decode it back to php array

$array = json_decode($local_source,true);

Answer 4

You can follow below given PHP example

$area = array('0' => array('id' => "1",'area' => 'Arappalayam'),
 '1' => array('id' => "2",'area' => 'Kalavasal')
 );
//callback function to do conversion
function convert($value){
 //convert only ID into integer 
 $value['id'] = intval($value['id']);
 return $value;
} 
$area = array_map('convert',$area); 
echo json_encode($area);
