php-openaiHow to use OpenAI API and PHP and cURL?
OpenAI API can be used with PHP and cURL to access the OpenAI API. The following example code shows how to use cURL to make a request to the OpenAI API:
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "https://api.openai.com/v1/engines/davinci/completions",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => "{\n \"prompt\": \"The quick brown fox\",\n \"max_tokens\": 50\n}",
CURLOPT_HTTPHEADER => array(
"Authorization: Bearer <YOUR_API_KEY>",
"Content-Type: application/json"
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $response;
}The output of the example code will be a JSON response from the OpenAI API.
