Array of objects in PHP - php

Question

I am new to PHP and trying to produce the following json output :
{
"contacts": [
{
"id": "1",
"name": "John Bob",
"email": "john#bob.com"
},
{
"id": "2",
"name": "Johnny Mac",
"email": "johnny#mac.com"
},
.....
]
}
and I have the following PHP code:
$final = array();
foreach ($contacts as $contact)
{
.....
$final[] = array(
'id' => (string)$id,
'name' => $name,
'email' => $email
);
}
header('Content-Type: application/json; charset=UTF-8');
echo json_encode($final, JSON_PRETTY_PRINT);
however, this outputs:
[
{
"id": "1",
"name": "John Bob",
"email": "john#bob.com"
},
{
"id": "2",
"name": "Johnny Mac",
"email": "johnny#mac.com"
},
]
I read over this tutorial and changed $final[] to $final['contacts'] but still couldn't produce the desired json file.

Answer 1

Either:
$final['contacts'][] = array(..);
or:
$contacts_output = array();
foreach ($contacts as $contact) {
$contacts_output[] = array(..);
}
$final = array('contacts' => $contacts_output);
echo json_encode($final, JSON_PRETTY_PRINT);

Answer 2

foreach ($contacts as $contact)
{
.....
$final['contacts'][] = array(
array( //insert all your array in contacts
'id' => (string)$id,
'name' => $name,
'email' => $email
);
}

Answer 3

Try this:
$final = array();
$final['contacts'] = array();
foreach ($contacts as $contact)
{
.........
$final['contacts'][] = array(
'id' => (string)$id,
'name' => $name,
'email' => $email
);
}

Answer 4

$final = array('contacts'=>[]);
foreach ($contacts as $contact)
{
$final['contacts'] []=
array( //insert all your array in contacts
'id' => (string)$id,
'name' => $name,
'email' => $email
);
}
