how to format json with array of json - php

Question

I want output in json like this
response:{url="www.google.com/raj.png", size=12.344KB},{url="www.google.com/raj2.png", size=12.344KB},{url="www.google.com/raj4.png", size=12.344KB}
But currently i am getting
"url=> www.google.com/img1.png size => 12.344 KB,url=> www.google.com/img2.png size => 12.344 KB"

Answer 1

//Using some loop here
{
$response[] = array('url' => 'url_value','size' => 'file_size');
}
//without loop hardcoded values:
$response = array ( array('url' => "www.google.com/raj.png",'size' => "12.344KB"),
array('url' => "www.google.com/img2.png",'size' => "10.344KB") );
return json_encode($response);

Answer 2

$out= Array(
Array('url'=>'www.goog', 'size'=>'12KB'),
Array('url'=>'moogle', 'size'=>'13KB')
);
echo Json_encode($out);

Answer 3

Not sure how you are formatting your array, but if you define it like this it should do the trick:
$response_array = array(
'response' => array(
array(
'url' => 'www.google.com/raj.png',
'size' => '12.344KB',
),
array(
'url' => 'www.google.com/raj.png',
'size' => '12.344KB',
),
array(
'url' => 'www.google.com/raj.png',
'size' => '12.344KB',
),
),
);
$respose_json = json_encode($response_array);
echo($response_json);
For looping through some results, try something like this:
$response_array = array('response' => array());
foreach($result_set as $result_item) {
$response_item = array();
$response_item['url'] = $result_item['url'];
$response_item['size'] = $result_item['size'];
$response_array['response'][] = $response_item;
}
$respose_json = json_encode($response_array);
echo($response_json);
With the $result_set above being whatever data you've pulled from a DB, server, etc.
