I’m attempting to create a string $contacts_data that holds all of the data in the correct format required to be passed in my CURLOPT_POSTFIELDS property. However, my page is bombing with this current setup.

Here is the current output of my $contacts_data:

['email' => '[email protected]',],['email' => '[email protected]',],

However when I try to echo that data into my CURLOPT_POSTFIELDS, the site breaks:

<?php

$json = file_get_contents('current.json');
$contacts = json_decode($json, true);

$contacts_data = "";

for ($i = 0; $i < count($contacts); $i++) {
    $contacts_data .= "[";
    $contacts_data .= "'email' => '" . $contacts[$i]['Email'] . "',";
    $contacts_data .= "],";
}

print_r($contacts_data);


$curl = curl_init();

curl_setopt_array($curl, [
  CURLOPT_URL => "https://test.api-us1.com/api/3/import/bulk_import",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS => json_encode([
    'callback' => [
        'requestType' => 'POST',
        'detailed_results' => 'true',
        'url' => 'test.com'
    ],
    'contacts' => [ echo $contacts_data; ]
  ]),
  CURLOPT_HTTPHEADER => [
    "Api-Token: 1234567890",
    "Content-Type: application/json",
    "accept: application/json"
  ],
]);

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}
