Answer 1

What you actually need to do is produce an array of results, which you can do by pushing values into an array in the loop, and then json_encode the array after the loop:
$print = array();
foreach($resultdata as $data){
$print[]= array(
"id" => $data['id'],
"username" => $data['username'],
"text" => $data['text']
);
}
print json_encode($print);

I don't get the point of having ',' but I'm guessing you want a valid json output. If so I guess that your result data is an array:
<?php
$result = [ 'data' => [
[
"id" => "17996292388215089",
"username" => "hanikfadhilah",
"text" => "Loh kapan ini huuu pengen"
],
[
"id" => "17877856039348099",
"username" => "titan_kdk",
"text" => "Mntb"
],
[
"id" => "17860767967398064",
"username" => "explorecentraljava",
"text" => "Terbaik fotonya lur"
]
]
];
so all what you need to do in order to get it as a valid json is:
print json_encode($result['data'], JSON_PRETTY_PRINT);
that produces output:
[
{
"id": "17996292388215089",
"username": "hanikfadhilah",
"text": "Loh kapan ini huuu pengen"
},
{
"id": "17877856039348099",
"username": "titan_kdk",
"text": "Mntb"
},
{
"id": "17860767967398064",
"username": "explorecentraljava",
"text": "Terbaik fotonya lur"
}
]
no need for any foreach loop.
json_encode()
