How to create this JSON in PHP? - php

Question

Sorry for the bad title, but I don't know how to create following JSON in PHP:
{
"id":"1",
"method":"getData",
"params":{
"options":{
"element":{
"id":"1a_ext",
"type":1,
"keyType":"externalkey"
},
"moreInfo":true,
"userFields":[
"id",
"name",
"longname",
"externalkey"
]
}
},
"jsonrpc":"2.0"
}
I don't know to do the part after "params" (how do I "put" options "into" params) - for the other parts I know what I have to do:
public static function getData(){
$json = array(
"id" => self::id(),
"method" => "getData",
"params" => array(
"id" => self::$userid,
"type" => self::$type
),
"jsonrpc" => "2.0"
);
$json = json_encode($json, true);
return self::request($json);
}
I would really appreciate your help, thanks!

Answer 1

You directly can assign to the params keys like
$json['params']['options'] = $your_options;
Full version of your code as an example
public static function getData(){
$json = array(
"id" => self::id(),
"method" => "getData",
"params" => array(
"id" => self::$userid,
"type" => self::$type
),
"jsonrpc" => "2.0"
);
# add something to param index
$json['params']['options'] = $your_options;
$json = json_encode($json, true);
return self::request($json);
}

You can create the this in array format in PHP and then JSON encode:
$arr = [
'id' => 1,
'method' => 'getData',
'params' => [
'options' => [
'element' => [
'id' => '1a_ext',
'type' => 1,
'keyType' => 'externalKey'
],
'moreInfo' => true,
'userFields' => [
'id',
'name',
'longname',
'externalKey'
]
]
],
'jsonrpc' => '2.0'
];
$json = json_encode($arr);

Instead of spoonfeeding, i would like to help related, Whenever if you find difficulties to create an array representation of a JSON then you should use var_export(array, true) the second parameter must be true to return the variable representation instead of outputting it
<?php
$json_str = '{
"id": "1",
"method": "getData",
"params": {
"options": {
"element": {"id": "1a_ext", "type": 1, "keyType": "externalkey"},
"moreInfo": true,
"userFields": ["id", "name", "longname", "externalkey"]
}
},
"jsonrpc": "2.0"
}';
$json_arr = var_export(json_decode($json_str, true), true);
print_r($json_arr);
check the output here https://paiza.io/projects/eUZZDsTsSFSM4m9WMl05Ow
$json_arr is an array representation for your JSON, now you can dynamic the array values
