使用curl将json数据添加到现有数组

Question

I'm using PHP to send an HTML post request using curl. I want to add more data to an existing JSON array at an URL. If I post a request, does it replace the data or does it add it to the existing array? Currently, I'm writing:

// Setup cURL
$ch = curl_init('http://www.barn-door.co.uk/wp-json/geodir/v1/farms'); 

curl_setopt_array($ch, array(
CURLOPT_POST => TRUE,
CURLOPT_RETURNTRANSFER => TRUE,
CURLOPT_HTTPHEADER => array(
    'Authorization: '.$authToken,
    'Content-Type: application/json'
),
CURLOPT_POSTFIELDS => json_encode($postData)
));

// Send the request
$response = curl_exec($ch);

// Check for errors
if($response === FALSE){
die(curl_error($ch));
}

// Decode the response
$responseData = json_decode($response, TRUE);

// Print the date from the response
echo $responseData['published'];

where $postData is my data in json format.

Thanks :)

Answer 1

you can merge your data before sending

// original data
$data = array("firstname" => "Foo");

// your new data
$additionalData = array("surname" => "Bar");

// merge/overwrite
$data = array_merge($data, $additionalData);

//result print_r($data); will output array("firstname" => "Foo", "surname" => "Bar")
