I was upgrading from PHP 7.4 to PHP 8 and suddenly this errors appears in my cURL request:
JavaScript
x
Fatal error: Uncaught ValueError: curl_setopt_array(): Argument #2 ($options) contains an invalid cURL option in ...
I use the following code to build the curl:
JavaScript
$options = array (
"CURLOPT_POST" => true,
"CURLOPT_HEADER" => true,
"CURLOPT_URL" => "https://example.example.com/api/example.php",
"CURLOPT_FRESH_CONNECT" => true,
"CURLOPT_RETURNTRANSFER" => true,
"CURLOPT_FORBID_REUSE" => true,
"CURLOPT_TIMEOUT" => 10,
"CURLOPT_FAILONERROR" => true,
"CURLOPT_POSTFIELDS" => $this->buildPostFields($postData),
"CURLOPT_HTTPAUTH" => "CURLAUTH_BASIC",
"CURLOPT_SSL_VERIFYPEER" => false //REMOVE IN PRODUCTION, IGNORES SELFSIGNED SSL
);
$ch = curl_init();
curl_setopt_array($ch, $options);
The targeted file is always an php extensions. ‘buildPostFields’ returns an array of the data.
Probably this errors accours because of my php upgrade to version 8, but I cannot find any hints in the documentation. I tried removing every line and then tried again. But it didn’t help.

Answer
The error is because you wrapped the constants with double quotes.
curl_setopt_array ( CurlHandle $handle , array $options ) : bool
options
An array specifying which options to set and their values. The keys should be valid curl_setopt() constants or their integer equivalents.
So it should be CONSTANT_NAME => value
JavaScript
$options = array (
CURLOPT_POST => true,
CURLOPT_HEADER => true,
CURLOPT_URL => "https://example.example.com/api/example.php",
CURLOPT_FRESH_CONNECT => true,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_FORBID_REUSE => true,
CURLOPT_TIMEOUT => 10,
CURLOPT_FAILONERROR => true,
CURLOPT_POSTFIELDS => $this->buildPostFields($postData),
CURLOPT_HTTPAUTH => CURLAUTH_BASIC,
CURLOPT_SSL_VERIFYPEER => false //REMOVE IN PRODUCTION, IGNORES SELFSIGNED SSL
);
$ch = curl_init();
curl_setopt_array($ch, $options);
