how to build a json return in php?

i have a function that looks like this.

function startChatSession($items) {


    foreach ($test as $chatbox => $void) {
            $items .= $this->chatBoxSession($chatbox);
        }

    if ($items != '') {
        $items = substr($items, 0, -1);
    }

    header('Content-type: application/json');
    ?>
    {
        "username": "<?php echo $_SESSION['username'];?>",
       "items": [
            <?php echo $items;?>
        ]
    }

    <?php
    exit(0);
}

i am interested in the second part of this function. I would like to translate it to sometihng like:

    echo json_encode(array(
            'username'=>$_SESSION['username'], 
            'items'=>$items
        )); 

    exit;

this kind of works, but not quite.

the response should look like:

{
    "username": "johndoe",
    "items": [{
        "s": "1",
        "f": "janedoe",
        "m": "dqwdqwd"
    }, {
        "s": "1",
        "f": "janedoe",
        "m": "sdfwsdfgdfwfwe"
    }, {
        "s": "1",
        "f": "janedoe",
        "m": "werwefgwefwefwefweg"
    }]
}

in my case it looks like:

{
    "username": "johndoe",
    "items": "\t\t\t\t\t   {\r\n\t\t\t\"s\": \"1\",\r\n\t\t\t\"f\": \"babydoe\",\r\n\t\t\t\"m\": \"test\"\r\n\t   },\t\t\t\t\t   {\r\n\t\t\t\"s\": \"1\",\r\n\t\t\t\"f\": \"\",\r\n\t\t\t\"m\": \"\"\r\n\t   }"
}

any ideas?

thanks

edit:

if i dump the $items i the something like:

{
    s: 1,
    f: babydoe,
    m:  test
}, {
    s: 1,
    f: babydoe,
    m:  test
}, {
    s:1,
    f: babydoe,
    m:  test
}, {
    s: 1,
    f: babydoe,
    m:  test
}

Change

$items = substr($items, 0, -1);

To:

foreach($items as $index => $d){
$items[$index] = substr($d, 0, -1);
}

Try this:

    echo json_encode(array(
        'username'=>$_SESSION['username'], 
        'items'=>array($items)
    ));

You need a multi level array.

See codepad for example.

Your $items array should look like this:

<?php
$items = array(
  0 => array('s'=>1, 'f'=>'janedoe', 'm'=>'dqwdqwd'),
  1 => array('s'=>1, 'f'=>'janedoe', 'm'=>'sdfwsdfgdfwfwe'),
  2 => array('s'=>1, 'f'=>'janedoe', 'm'=>'werwefgwefwefwefweg')
);

echo json_encode(array(
        'username'=>$_SESSION['username'], 
        'items'=>$items
    ));
?>
