php - Create a JSON array with objects

Question

I am trying to create a JSON array through PHP in that format:

{
 "Commands":[
 {
 "StopCollection":true
 },
 {
 "Send":false
 },
 {
 "HeartbeatSend":60
 }
 ]
}

The closest I got to do that is: by using JSON_FORCE_OBJECT

 $commands = array();
 $commands['Commands'] = array();
 array_push($commands['Commands'],array('StopCollection' => true));
 array_push($commands['Commands'],array('Send' => false));
 array_push($commands['Commands'],array('HeartbeatSend' => 60));
 $jsonCommands = json_encode($commands, JSON_FORCE_OBJECT);

Which outputs

{
 "Commands":{
 "0":{
 "StopCollection":true
 },
 "1":{
 "Send":false
 },
 "2":{
 "HeartbeatSend":60
 }
 }
}

And using (object)

 $commands = (object) [
 'Commands' => [
 'StopCollection' => true,
 'Send' => false,
 'HeartbeatSend' => 60
 ]
 ];
 $jsonCommands = json_encode($commands);

Which outputs

{
 "Commands":{
 "StopCollection":true,
 "Send":false,
 "HeartbeatSend":60
 }
}

Both are close but I need Commands to be an array of objects without a key. How do I do that?

• Ralph Thomas Hopper: you solved your own issue, as you said, you need commands to be an ARRAY or objects :)

Answer 1

If you want to remove indexes from $commands Try,

json_encode( array_values($commands) );

• parpar: If I understand it correctly, this should be the answer

Answer 2

You can just do this

$commands = array(
 'Commands' => array(
 array('StopCollection' => true),
 array('Send' => false),
 array('HeartbeatSend' => 60)
 )
 );
$jsonCommands = json_encode($commands);
print_r($jsonCommands);

Answer 3

Here you go:

$arr["Commands"] = [
 ["StopCollection" => true],
 ["Send" => false],
 ["HeartbeatSend" => 60],
];
echo json_encode($arr);
