$key = "sk-CcbPkD9...................";

$prompt = $_POST['prompt'];

$data = [

        "model" => "gpt-3.5-turbo",

        'messages' => [

               "content" => $prompt
           ]
        ],
        'temperature' => 0.5,
        "max_tokens" => 200,
        "top_p" => 1.0,
        "frequency_penalty" => 0.52,
        "presence_penalty" => 0.5,
        "stop" => ["11."],

How to Integrate and Use ChatGPT in PHP?

It is a process of integrate ChatGPT in any PHP Project. You need a ChatGPT API key and some PHP development skills to integrate ChatGPT and use it in PHP project. This guide will tell step-by-step methods in simple way so that anyone integrate without any difficulty.

Create an HTML form with text input and a submit button.
Create a form in First Step
Create form using post method with a text input for prompt and a submit button. Code is:
<form method=”POST”>
<label>Prompt</label>: <input type=”text” name=”prompt” id=”prompt”></br>
<input type=”submit” value=”Submit” name=”submit”>
</form>
Create variables for the API key
Step Two
Create a variable to store the API key value. Receive prompt as a input text using POST method. and $data array variable. You will get this data from ChatGPT itself.
Here is the code:
$key = "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";
$prompt = $_POST['prompt'];
$data = [ "model" => "gpt-3.5-turbo",
'messages' =>
[
[ "role" => "user", "content" => $prompt ]
],
'temperature' => 0.5,
"max_tokens" => 200,
"top_p" => 1.0,
"frequency_penalty" => 0.52,
"presence_penalty" => 0.5,
"stop" => ["11."],
];
Note: Use your API key, this API key is just for demo.
Use CURL
Step Three
In this step use curl to connect and communicate with ChatGPT. Initialize CURL, and fetch the URL. Encode the $data variable of STEP 2 using json_encode function. Then pass headers and execute it and receive the response in $response variable.
Here is the code:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://api.openai.com/v1/chat/completions');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
$headers = [];
$headers[] = 'Content-Type: application/json';
$headers[] = 'Authorization: Bearer '.$key; curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$response = curl_exec($ch);
Close the CURL and Display the Output
Step Four
Close CURL, and decode the data using json_decode function. The decode data is the response of ChatGPT against the user input prompt.
Here is the code:
if (curl_errno($ch))
echo ‘Error:’ . curl_error($ch);
curl_close($ch);
$response = json_decode($response,true);
echo “<pre>”;
print_r($response[‘choices’][0][‘message’][‘content’]);
