php how to send this data threw curl - php

Question

I have to send this data threw curl:
-d '{"payer": {
"default_payment_instrument":"BANK_ACCOUNT",
"allowed_payment_instruments":["BANK_ACCOUNT"],
"default_swift":"FIOBCZPP",
"contact":{"first_name":"First",
"last_name":"Last",
"email":"first.last#example.com"
}
},
}'
How am I supposed to save those data into fields variable?
$fields = {
"payer": {
"default_payment_instrument":"BANK_ACCOUNT",
"allowed_payment_instruments":["BANK_ACCOUNT"],
"default_swift":"FIOBCZPP",
"contact":{"first_name":"First",
"last_name":"Last",
"email":"first.last#example.com"
}
},
};
$field_string = http_build_query($fields);
curl_setopt($process, CURLOPT_POSTFIELDS, $field_string);

Answer 1

This is GoPay right?
Do something like this:
$fields = [
"payer" => [
"default_payment_instrument" => "BANK_ACCOUNT",
"allowed_payment_instruments" => ["BANK_ACCOUNT"],
"default_swift" => "FIOBCZPP",
"contact" => [
"first_name" => "First",
"last_name" => "Last",
"email" => "first.last#example.com"
]
]
];
$json = json_encode($fields);
curl_setopt($ch, CURLOPT_POSTFIELDS, $json);

Ok, posting stuff with cURL. Here you go...
<?php
$target_url = "http://domain.dev/post-acceptor.php";
$data_to_post = array(
"payer" => array(
"default_payment_instrument" => "BANK_ACCOUNT",
"allowed_payment_instruments" => "BANK_ACCOUNT",
"default_swift" => "FIOBCZPP",
"contact" => array(
"first_name" => "First",
"last_name" => "Last",
"email" => "first.last#example.com"
)
)
);
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $target_url);
curl_setopt($curl, CURLOPT_POST, count($data_to_post));
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data_to_post));
$result = curl_exec($curl);
curl_close($curl);
Notes:
you might try to turn your JSON into an PHP array by using json_decode()
