Use PHP's native json_encode, like this:

<?php
$arr = array(
    array(
        "region" => "valore",
        "price" => "valore2"
    ),
    array(
        "region" => "valore",
        "price" => "valore2"
    ),
    array(
        "region" => "valore",
        "price" => "valore2"
    )
);

echo json_encode($arr);
?>

Update: To answer your question in the comment. You do it like this:

$named_array = array(
    "nome_array" => array(
        array(
            "foo" => "bar"
        ),
        array(
            "foo" => "baz"
        )
    )
);
echo json_encode($named_array);

Try this:

$data = json_decode($your_json_string, TRUE);

the second parameter will make decoded json string into an associative arrays.

Hi there. I’m struggling to get my head around converting arrays into JSON format. I have some code that queries my database and successfully returns 2 columns (contact_type and contact_det) into an array:

array(3) (
  [0] => array(4) (
    [contact_type] => (string) home_tel
    [0] => (string) home_tel
    [contact_det] => (string) 02072726347
    [1] => (string) 02072726347
  )
  [1] => array(4) (
    [contact_type] => (string) personal_mobile
    [0] => (string) personal_mobile
    [contact_det] => (string) 01977591328
    [1] => (string) 01977591328
  )
  [2] => array(4) (
    [contact_type] => (string) work_tel
    [0] => (string) work_tel
    [contact_det] => (string) 01977591328
    [1] => (string) 019775913...

Can anybody tell me the best/easiest way to convert the above array data into JSON format, please?

Many thanks

just use only

$response=array();
$response["0"]=array("ip"     => "192.168.0.1",
                     "port"   => "2016");
$json=json_encode($response,JSON_FORCE_OBJECT);
