I have the following code and it is not working, I just get string(0) "" This code is a copy of a DeepL curl script that creates a glossary which works perfect, I just changed the url and options in DATA. I'm also not getting any errors if I change the auth. code.

<?php
$text = 'Hi there';
$source_lang = "en";
$target_lang = "de";
$glossary_id = "";
$tag_handling = "xml";
$ignore_tags = "x";
$formality = "";
$url = ";;
$authKey = "hidden";

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

$headers = array(
   "Authorization: DeepL-Auth-Key .$authKey",
   "Content-Type: application/json",
);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);

$data = <<<DATA
text=$text&source_lang=$source_lang&target_lang=$target_lang&tag_handling=$tag_handling&ignore_tags=$ignore_tags&formality=$formality&glossary=$glossary_id
DATA;

curl_setopt($curl, CURLOPT_POSTFIELDS, $data);

//for debug only!
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);

$resp = curl_exec($curl);

// Check for errors and display the error message
if($errno = curl_errno($curl)) {
    $error_message = curl_strerror($errno);
    echo "cURL error ({$errno}):\n {$error_message}";
}

curl_close($curl);
var_dump($resp);
?>

• You also need to check curl_getinfo($ch, CURLINFO_HTTP_CODE) == 200 – shingo Commented Mar 17 at 6:11
• Thanks, the Unexpected HTTP code: 403, so is that the DeepL server issue or at my end? – Peter Commented Mar 17 at 8:01
• 1 @Peter, if you don't believe this is your issue, then you may contact deepl and report this bug. BTW you set content type to application/json but sent application/x-www-form-urlencoded data. – shingo Commented Mar 17 at 8:44
• 1 And you should use http_build_query() to properly build $data. – Olivier Commented Mar 17 at 9:04
• 1 Why application/xml? You're not sending XML. – Olivier Commented Mar 17 at 9:31

Can you try below updated code,

<?php
$text = 'Hi there';
$source_lang = "en";
$target_lang = "de";
$tag_handling = "xml";
$ignore_tags = "x";
$formality = "";
$url = "https://api.deepl/v2/translate";
$authKey = "hidden";

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

$headers = array(
   "Authorization: DeepL-Auth-Key $authKey",
   "Content-Type: application/json",
);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);

$data = json_encode([
    'text' => [$text],
    'source_lang' => $source_lang,
    'target_lang' => $target_lang,
    'tag_handling' => $tag_handling,
    'ignore_tags' => $ignore_tags,
    'formality' => $formality
]);
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);

//for debug only!
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);

$resp = curl_exec($curl);

// Check for errors and display the error message
if ($errno = curl_errno($curl)) {
    $error_message = curl_strerror($errno);
    echo "cURL error ({$errno}):\n {$error_message}";
} else {
    echo "Response:\n";
    print_r(json_decode($resp, true));
}

curl_close($curl);
?>

The following works perfect and was put into production yesterday, thanks to all.

<?php
$authKey = $_POST["auth_key"];
$_text = $_POST["text"];
$target_lang = $_POST["target_lang"];
$formality = $_POST["formality"];
$glossary_id = $_POST["glossary_id"];

$source_lang = "en";
$tag_handling = "xml";
$ignore_tags = "x";

$url = "https://api.deepl/v2/translate";

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

$headers = array(
   "Authorization: DeepL-Auth-Key $authKey",
   "Content-Type: application/x-www-form-urlencoded",
);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);

$data = array(
    'text' => $_text,
    'source_lang' => $source_lang,
    'target_lang' => $target_lang,
    'tag_handling' => $tag_handling,
    'ignore_tags' => $ignore_tags,
    'formality' => $formality,
    'glossary' => $glossary_id
);
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data));

//for debug only!
//curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
//curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);

$resp = curl_exec($curl);

// Check HTTP status code and display the error message
if (!curl_errno($curl)) {
  switch ($http_code = curl_getinfo($curl, CURLINFO_HTTP_CODE)) {
    case 200:  # OK
      break;
    default:
      echo 'DeepL Error: Unexpected HTTP code: ', $http_code;
  }
}

// Check for errors and display the error message
if($errno = curl_errno($curl)) {
    $error_message = curl_strerror($errno);
    echo "DeepL Error: cURL error ({$errno}):\n {$error_message}";
}

curl_close($curl);
echo $resp;
?>
