Php array of arrays to json in loop - php

Question

I am new in php, please help with my code.
I am trying to create PHP json for IOS app. Json should looks like this
{"items": [
{
"ID":12,
"name1":"some name",
"name2":"some name2"
},
{
"ID":13,
"name1":"another name",
"name2":"another name2"
},] }
Here is my PHP code part
$keys = array(ID, name1, name2);
while ($row = mysqli_fetch_array($result))
{
extract($row);
$values = array($row['ID'], $row['name1'], $row['name2']);
$response = array_combine($keys, $values);
header('Content-Type: application/json, charset=utf-8');
echo json_encode($response, JSON_UNESCAPED_UNICODE);
}
This gives me result like this
{
"ID":12,
"name1":"some name",
"name2":"some name2"
}
{
"ID":13,
"name1":"another name",
"name2":"another name2"
}
Can anybody help me with this?
Thanks in advance.

Answer 1

You need to build your array, and then encode the JSON outside of the loop for a start;
$keys = array(ID, name1, name2);
$items = array();
while ($row = mysqli_fetch_array($result))
{
extract($row);
$values = array($row['ID'], $row['name1'], $row['name2']);
$item = array_combine($keys, $values);
$items[] = $item;
}
header('Content-Type: application/json, charset=utf-8');
echo json_encode(array("items"=>$items), JSON_UNESCAPED_UNICODE);
Here we build up an array of your items into $items, and then encode them all outside of the loop.

Seems you are new or really don't know something about json yet
but i'll try to help you
just simply stored it in associative array an assign items as it's index
$response = array(
'items' => array_combine($keys, $values)
);
header('Content-Type: application/json, charset=utf-8');
echo json_encode($response, JSON_UNESCAPED_UNICODE);
