With the rapid development of artificial intelligence technology, more and more innovative applications are emerging, and AI art is one of the most prominent ones. Midjourney is a leading AI art platform that allows users to generate unique artworks based on text or images. In this article, we will introduce how to use PHP to integrate with Midjourney API and develop a simple AI art application.
Before starting, ensure that you have installed the PHP environment and a compatible web server. If PHP is not installed, you can download it from the official PHP website and follow the instructions for installation.
To use Midjourney's API service, you need to register an account on Midjourney. Once registered, log in to your account.
Go to the account settings on Midjourney and find the API key section. Copy the API key, as you will need it in your PHP code later.
Create a new PHP file in your project directory and name it “index.php”. This file will handle the communication with Midjourney API.
To communicate with Midjourney, we will use PHP's cURL library. Below is the PHP code that sends a POST request to the Midjourney API:
<?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;
?>
Make sure to replace “YOUR_API_KEY” with the API key you obtained from Midjourney.
Next, we will create a simple HTML page for the user to input the text they want to be turned into art. Here’s a basic form example:
<!DOCTYPE html>
<html>
<head>
<title>AI Art Application</title>
</head>
<body>
<h1>AI Art Application</h1>
<form method="POST" action="index.php">
<label for="text">Enter the text you want to draw:</label><br>
<input type="text" id="text" name="text" required><br><br>
<input type="submit" value="Generate Artwork">
</form>
<div>
<?php echo $response; ?>
</div>
</body>
</html>
Save and close the “index.php” file, then upload the entire project to your web server. Visit your PHP application in the browser, input the text you want to turn into art, and click the “Generate Artwork” button. After a short wait, you will see the artwork generated by Midjourney.
This tutorial showed how to use PHP to integrate with Midjourney API and develop a simple AI art application. Through this guide, you learned how to send HTTP requests with PHP and process the API responses. Although this is a basic example, you can expand and optimize it to develop more complex and interesting AI applications.
