Zero Basic Introduction: A simple tutorial on using PHP to connect Midjourney to develop AI painting applications

Introduction:
With the development of artificial intelligence technology, more and more innovative applications were developed. And AI painting application is one of them. Midjourney is a platform that provides AI painting services, which can generate unique art paintings based on text or pictures input by users. This article will introduce you to how to use PHP to write code and connect it to Midjourney to develop a simple AI painting application.

Preparation:
First, make sure that the PHP interpreter and a compatible server environment have been installed on your computer. If it is not installed yet, you can download the installation package from the PHP official website and follow the instructions to install it.

Step 1: Register a Midjourney account
First, we need to register a Midjourney account. Visit the Midjourney official website and click the registration button. After filling in the necessary personal information and successfully registering, log in to your account.

Step 2: Obtain API Key
In the Midjourney account, we need to obtain an API key to be able to use their services. In your profile or settings page you should be able to find the API key and copy it to save it.

Step 3: Create PHP file
Create a new php file in the PHP project directory of your choice and name it "index.php".

Step 4: Connect to Midjourney API
First, we need to introduce PHP’s cURL library. Add the following code at the beginning of the index.php file:

<?php
function send_post_request($url, $data){
    $handle = curl_init();
    curl_setopt($handle, CURLOPT_URL, $url);
    curl_setopt($handle, CURLOPT_POST, true);
    curl_setopt($handle, CURLOPT_POSTFIELDS, http_build_query($data));
    curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
    $response = curl_exec($handle);
    curl_close($handle);
    return $response;
}

$api_key = "YOUR_API_KEY";
$text = $_POST['text'];

$data = array(
    'api_key' => $api_key,
    'text' => $text
);

$url = "https://api.midjourney.com/ai-painting";
$response = send_post_request($url, $data);

echo $response;
?>

Please note that "YOUR_API_KEY" is replaced with the API key obtained previously. In the above code, we define a function named "send_post_request" to send a POST request to Midjourney. Then, we defined some variables that contain the API key and user-entered text.

Step Five: Create HTML Page
In the index.php file, we will add some HTML code to create a simple user interface. You can design it according to your own preferences. The following is a basic example:

<!DOCTYPE html>
<html>
<head>
    <title>AI绘画应用</title>
</head>
<body>
    <h1>AI绘画应用</h1>
    <form method="POST" action="index.php">
        <label for="text">请输入你想绘画的文字：</label><br>
        <input type="text" id="text" name="text" required><br><br>
        <input type="submit" value="生成画作">
    </form>
    <div>
        <?php echo $response; ?>
    </div>
</body>
</html>

Step 6: Test the application
Save and close the index.php file, and deploy the entire project directory to the server. Enter your project's URL into your browser, and you'll see a simple form prompting you to enter the text you want to draw. After inputting, click the "Generate Painting" button, wait a moment, and you will see the painting results returned by Midjourney.

Summary:
This tutorial introduces how to use PHP to connect with Midjourney to develop an AI painting application. With this simple tutorial, we learned how to use cURL to send requests and handle responses. I hope this article can help you and encourage you to explore more interesting artificial intelligence applications. Although this is just a simplified example, it can serve as a basis for your further expansion and optimization.
