Create your own ChatGPT prompt with PHP
The news is out, yesterday OpenAI released the ChatGPT API. This means that anyone can integrate their models into their own apps and websites. This has the following advantages:
- You won't get locked out when its busy
- Its cheaper than ChatGPT Plus
- 10x cheaper than GPT3
- You can whitelabel it for your own brand
- You can customise it to make all kinds of stuff
- It's pretty cool
I recently used the ChatGPT API to create a book recommender for those who can't decide which book to read next, but the possibilities are endless.

How to create your own prompt
I've been playing around with this API and have created my own prompt which can be integrated into any static webpage which supports PHP.
The first step is to create an API key. This is super simple to do, just create an openAI account and go to https://platform.openai.com/account/api-keys to create your key.
Simply copy the following code into a blank HTML page and put paste in your API key:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Homemade chatGPT prompt</title>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=Edge">
<meta name="description" content="Create your own chatGPT prompt">
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
</head>
<body>
<h1>chatGPT Prompt</h1>
<p>Ask a question to chatGPT</p>
<div class='result'>
<p>
<?php
session_start();
// Set your API key and the endpoint URL for the OpenAI API
$api_key = '[ADD-URL-KEY']; //add API key here
$endpoint_url = 'https://api.openai.com/v1/chat/completions';
// Check if the form has been submitted
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
// Get question
$input = $_POST['input'];
// Set up the request data for the OpenAI API
$data = array(
//'temperature' => 0.5,
'max_tokens' => 60,
//'frequency_penalty' => 0,
//'presence_penalty' => 0,
'model' => 'gpt-3.5-turbo', // Specify the model to use
'messages' => [
[
'role' => 'user',
'content' => $input
]
]
);
//add chat history to data input array
if (isset($_SESSION['history'])) {
array_unshift($data['messages'], ...$_SESSION['history']);
$data['messages'] = array_values($data['messages']);
//echo json_encode($_SESSION['history']) . "<br><br>"; //un-comment to show chat history
//echo json_encode($data) . "<br><br>"; //un-comment to show data input array
}
// Set up the HTTP headers for the request
$headers = array(
'Content-Type: application/json',
'Authorization: Bearer ' . $api_key
);
// Send the request to the OpenAI API using cURL
$ch = curl_init($endpoint_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$response = curl_exec($ch);
curl_close($ch);
// Parse the response from the OpenAI API
$result = json_decode($response, true);
$answer = $result['choices'][0]['message']['content'];
// Output the answer to the user
echo $answer;
//save to message history
$user_input = array([
'role' => 'user',
'content' => $input]
);
$user_output = array([
'role' => 'assistant',
'content' => $answer]
);
$history = array_merge($user_input, $user_output);
if (isset($_SESSION['history'])){
$_SESSION['history'] = array_merge($_SESSION['history'], $history);
} else {$_SESSION['history'] = $history;}
}
?>
</p>
</div>
<div class="prompt-form">
<form method="post">
<input type="text" name="input" id='input' placeholder="Ask chatGPT" required="">
<input type="submit" name="submit" value="Ask chatGPT">
</form>
</div>
</body>
</html>
As well as answering your prompts, this will save your message history for the duration of your session so you can go down that familiar rabbit hole with the chat bot.
Enjoy!!
