formatted json format in php webservices - php

Question

I am new in PHP. I am trying to format JSON. Here's the relevant code:
$query = mysql_query("SELECT *
FROM `micards` m
JOIN user u ON m.`mobile` = u.phone");
while ($row = mysql_fetch_assoc($query)) {
$response["success"] = 1;
$name = array('name'=>$row["name"],'email'=>$row["email"],'mobile'=>$row["mobile"]);
$phone[] = array('phone'=>$row["phone"],array('card'=>$name));
$response["contacts"] = $phone;
}
echo json_encode($response);
I'm getting this output:
{
"success": 1,
"contacts": [{
"phone": "919898989898",
"0": {
"card": {
"name": "abcd",
"email": "vwxy#test.com",
"mobile": "919898989898"
}
}
}, {
"phone": "919898989898",
"0": {
"card": {
"name": "abcd",
"email": "rstp#test.com",
"mobile": "919898989898"
}
}
}, {
"phone": "8686868686",
"0": {
"card": {
"name": "pan",
"email": "pnqr#gmail.com",
"mobile": "8686868686"
}
}
}, {
"phone": "8686868686",
"0": {
"card": {
"name": "monk",
"email": "abcd#gmail.com",
"mobile": "8686868686"
}
}
}]
}
But I want it to be:
{
"success": 1,
"contacts": [{
"phone": "919898989898",
{
"card": {
"name": "abcd",
"email": "vwxy#test.com",
"mobile": "919898989898"
}
},
{
"card": {
"name": "abcd",
"email": "rstp#test.com",
"mobile": "919898989898"
}
}
}],
[{
"phone": "8686868686",
{
"card": {
"name": "panky",
"email": "pnqr#gmail.com",
"mobile": "8686868686"
}
},
{
"card": {
"name": "panky",
"email": "abcd#gmail.com",
"mobile": "8686868686"
}
}
}]
}
What can I do to get the above output?

Answer 1

just change this part:
$phone[] = array('phone'=>$row["phone"],array('card'=>$name));
$response["contacts"] = $phone;
to
$response["contacts"][] = array('phone'=>$row["phone"],array('card'=>$name));

Answer 2

Just copy and paste this code
while ($row = mysql_fetch_assoc($query)) {
$response["success"] = 1;
$name = array('name'=>$row["name"],'email'=>$row["email"],'mobile'=>$row["mobile"]);
$response["contacts"][] = array('phone'=>$row["phone"],array('card'=>$name));
}

Answer 3

Please change
$phone[] = array('phone'=>$row["phone"],array('card'=>$name)) to
$phone[] = array('phone'=>$row["phone"],'card'=>$name)
;

Answer 4

My guess is that there is a problem with associative arrays and the way you are packing it. You can try to organize your response array like this:
$response = [
'success'=>1,
'contacts'=>[
'phone'=>$row['phone'],
'card'=>[
'name'=>$row['name'],
'email'=>$row['email'],
'mobile'=>$row['mobile']
]
]
];
It should work, didn't check it out thou.
